Brief mass combat idea

Here is a brief mass combat idea meant for old school D&D or OSR games. I'm using ascending AC in my examples because that's what I use in my games.

Here is the idea:

10 1st level fighters count as a single fighter with a +10 attack bonus until the end of the round.

They attack as one. They deal one die of damage (say, 1d8 if they're using swords).

They add one point of damage for each point over the AC (if using ascending AC).

By Dean Spencer

Let's say 10 bandits are attacking your 5th-level  PC, who has AC 17. They roll 9. Adding a +10 bonus, this means 19, two points more than needed to hit. They deal 1d8+2 damage.

The best part about this idea is how it vastly simplifies things.

If you decide only 4 or 6 fighters can attack the PC at a time, just reduce the bonus to +4 or +6.

If the PC slays a couple of bandits, reduce the bonus to +8. And so on.

In some cases, you can just add up all HD. If your PC is attacked by a 3rd level fighter and 3 bandits, they can make one single attack with +6.

It also makes goblins, etc., dangerous though all levels. If your PC in magical plate and shield gets attacked by ten goblins, it is VERY LIKELY that ate least one of them will get a good stab!

This will probably be useful when PCs have multiple henchmen too. One roll, period.

Is this similar to actually rolling each attack individually? Well, it varies a lot depending on AC, number of foes, etc. Apparently, the bigger the group, the smaller the damage each individual adds (which might be explained by fewer people being able to attack at the same time). 

Let's try with six goblins attacking a fighter in plate [AC 16], using B/X (or OSE) rules. The usual damage per round (DPR) would be around 5.25. With my proposed rule, it would be about 4.4. 

If the fighter is unarmored, DPR is also similar (11.55 versus 9.78, more or less). Not bad.

And if the fighter has plate, armor, and some magic bonus to AC? Let's say AC 20? An extreme case, but... Then damage doubles from about 1.05 to 2.28. So the rule works as intended!

(These numbers were calculated with the help of AI... let me know if they're wrong!)

I probably wouldn't use such a rule if you're fighting a couple of giants, for example; just for low-level foes. Likewise, allowing 15 goblins to attack you at once sounds unwieldy; I'd keep the limit at 10 for now, and you ever fight 20 goblins at once they cannot attack you as a single unit (treat them as two groups).

I probably COULD use this idea for huge mass battles, just adding a few zeroes when needed.

Say, a force of 90 knights clash with 50 enemy knights. The 90 knights attack with a +9 bonus, etc. They deal 1d8 damage (or whatever) plus the margin of success. Then just multiply damage (or casualties) per 10, and reduce the opposing force equally.

I haven't played-tested this. But I have a good feeling about it...

I want LESS!

Most of my time playing and reading RPGs has been ruled by the “undisciplined pursuit of more.”

I played several RPGs and took pride in trying new ones. I favored "universal" systems where I could create endlessly detailed PCs and do anything I wanted. I also collected monster manuals for my D&D-ish needs.

This process has been somewhat useful in helping me discover my tastes and needs.

However, there has also been much waste. I read only a fraction of the RPGs I buy and play an even smaller fraction of the RPGs I read. Nowadays, I'm embracing "the disciplined pursuit of less."

In other words, I want less: fewer monsters, fewer spells, fewer magic items, fewer stats, and simpler systems.

This partly reflects my appreciation for minimalism, but it goes beyond that. I believe that having fewer elements makes each one more important and meaningful.

While having a multitude of monsters is fun, each Monster Manual contains more creatures than entire worlds like Middle-earth, Barsoom, Lankhmar, or the Hyborian Age (not to mention most horror and sci-fi settings). It becomes virtually impossible for PCs to understand each individual monster with any depth.

Take dragons, for example. The dragons of mythology and literature are often unique individuals, like Smaug, Fafnir, Tiamat, Drogon. Each is distinct and memorable. But the 2e MM (my favorite!) has about more than a dozen dragon types. If a D&D party sees Smaug, it is just another red dragon (they don't even need to interact to know that he is chaotic, since he is red; but this is another issue).

[Another thing I've been considering is how adding more monsters to a game doesn't make it any different from "standard" D&D, but replacing existing monsters creates a completely new kind of setting. Take Curse of Strahd, for example: it includes few "demihumans," and even the elves are distinct from the familiar elves we're used to. This seems to hold true for most of my favorite settings and modules, and I think I might never run an adventure containing orcs again.]

Magic items are the same: Excalibur or Stormbringer are memorable, and so is Sting. In D&D, a first-level party often has dozens of magic items. Eventually, they discard some of them as they reach higher levels. This abundance devalues magic items and magic in general.

I feel the same way about rules.

I’ve run a few 5e campaigns. 5e is a more "complete" game than B/X. However, it requires ten times the page count to achieve this. So, I’ve been asking myself: is 5e ten times more complete than B/X? And the answer is no. Same goes for AD&D.

[Sure, I could use a one-page RPG. In the end, this ultimately comes down to a matter of taste.]

Spell selection has also been a headache, leading to imbalance and analysis paralysis.

I like customizing characters, but I don’t need dozens of classes and races. I really enjoy the simplicity of being able to say the bandit leader is a "fighter 5" and leaving it at that.

When you have fewer elements, you can connect them more meaningfully. For example, elves resist ghouls. The undead are raised by demons. All aberrations come from other dimensions, while monsters are created by mages. Etc.

And to be honest, this would make way more likely that my players would even REMEMBER most of this stuff.

In short, many of my current issues with D&D could be solved by just having less.

Goodman Games

In addition to the amazing Dungeon Crawl Classics RPG (DCC RPG), I really like The Dungeon Alphabet, The Monster Alphabet and The Cthulhu Alphabet. They are near system-less and full of awesome stuff to inspire your games. I still haven't read How to Write Adventure Modules That Don't Suck but it is also on sale. All of them 40% off.

They also publish awesome adventures; alas, few are on sale, but fortunately Doom of the Savage King, the one I am currently running, is 40% off! Recommended! Same for Jewels of the Carnifex, which I reviewed here.

Necrotic Gnome

Several Old School Essentials titles are also on sale in addition to Old-School Essentials Classic Fantasy: Rules Tome. I really like Old-School Essentials. It is basically a concise, well-organized version of my favorite D&D (B/X). The SRD is great. the version that interests me the most is the advanced version - it is NOT an AD&D clone, but B/X with many new options taken from AD&D, dragon magazine, etc. For players and DMs.

Sine Nomine Publishing

Worlds Without Number is 40% off. I have only read the free version briefly, but seems very good overall, and I've appreciated many other titles form the same author, including Scarlet Heroes and Silent Legions (maybe my favorite OSR take on horror and Lovecraft).

I think that's it for now. If you know any other books on sale that you'd recommend (especially if it is 40% off), let me know in the comments and I'll add it to my list. Feel free to promote your own products!

Monster taxonomy and organization

It seems that the new 2025 Monster Manual organizes EACH  monster alphabetically. This means a "Green Dragon" is found under "G". In the 2014 Monster Manual (and most MMs before that), all dragons were found under "D", for dragon. The same happens with giants, demons, etc.

I think this is an awful decision.

Not that this is simple. One reason there's so much debate over monster classification (and issues like orcs being inherently evil) is that taxonomy itself is complex. In the real world, we classify living beings into categories like Domain, Kingdom, Phylum, Class, Order, Family, Genus, and Species. Can a green dragon interbreed with a red dragon? There is no "right" answer, but I'd guess they can. What about a gold dragon? Applying real taxonomy to fantasy creatures is not easy or ideal.

But let's look at this from a practical standpoint

Should we have one single entry for each species? That is impossible because we need many entries for humans (bandits, clerics, druids, etc.).

Besides real taxonomy, how can we organize monsters?

One alternative I really like is monster type. This is one of the main points of my Teratogenicon. Undead have LOTS in common to each other, and if you ever want to create your won, looking at existing undead is more useful than calculating CR.

There are other practical reasons to use monster type.

First, let's assume you are new to D&D, and you don't really know the difference between demons and devils. Or maybe you vaguely remember playing 2e and you don't even KNOW there are monsters called either of these things.

You go looking for an explanation in the MM. You turn to "D" and... there is nothing.

Can you see the problem?

On the other hand, let's say you're an experienced DM and you want to build your own dungeon! This is going to be a hellish cave, full of demons... Now let's find some o populate it! Where do you look for them? Again, you've got nothing. At best, the MM has a list of "fiends" that include demons, devils and others.

And what if - unimaginable though it is - you forget the name of a particular demon you once saw and want to use as the villain?

The only way this is useful is if you use strictly for reference. You never create your own adventures, but maybe you're running a module that lists "1d4 green dragons" on the encounter table and you have to check it in the MM (that is not great either; most adventures should provide you with the relevant stats to avoid page-flipping and book-flipping, but modern D&D is so crunchy that this is nearly impossible).

This might be a radical, but I think a good MM could be divided in 20ish chapters, including the 14 monster types with a few subdivisions. For example:

Aberration

Beast

(Giant beasts)

Celestial

Construct

(Golems)

Dragon

(True dragons)

Elemental

(True elementals)

Fey

Fiend

(Explaining differences between demons, devils, etc.)

Giant

(True giants)

Humanoid

(maybe separate species from professions)

Monstrosity

Ooze

Plant

Undead

(maybe corporeal/incorporeal)

To clarify, "true" dragons, elementals and giants have that word in their names: e.g., Green Dragon, Hill Giant. To make things even clearer, D&D could use different names for wyverns and trolls. For example, "draconians", "dragon-like", "draconic creatures", "gigantic humanoids" (notice that troll is a "giant" but "giant bat" is not).

Calling a wyvern a "dragon" makes the idea of "natural language" impossible, since you'd have to explain (or assume) the meaning of the word "dragon" every time you find a "dragon-slaying sword", etc.

There are a few obvious problems to this approach.

First, the monstrosities are so numerous that the alphabetical approach just feels easier. In addition, they are not always easy to separate from aberrations (gricks and grells - what are they?). In fact, when I wrote Teratogenicon I had to go back to 3e to find a good definition of aberrations.

Some subdivisions would need further reflection. Should dragons be listed alphabetically, or should chromatic dragons be separated from metallic? Not sure.

But, from a learning or world-building approach, this would be nearly perfect. 

It also gives the MM a more "in universe" feel. When an average peasant sees a "dragon", "green" is not the first thing that comes to mind. Similarly, a "death knight" is an undead first, and for the untrained eyes it is not that different than other ghosts or apparitions. People will just run and call this place "cursed"!

The "monster type" division, therefore, is also teleological.

In addition, you could easily create an alphabetical index of each creature for easy referencing (with page numbers, of course), and this list could include both "dragons" and "green dragons", under D and G. You could add page numbers to modules and encounter tables too, but maybe that'd be too much to ask...

In conclusion, I dislike the new organization. It makes it more difficult to find some monsters and put them into proper context. It makes the game less coherent and more difficult to learn. I will not say I have the perfect answer, but I can say I find the former approach preferable to the current mess.

Yam-Shaped Campaigns

This is not my idea; the term may have been created by Sly Flourish but I couldn't find the exact source. In any case, I think it is a concept worth discussing and spreading.

Many people discuss "railroad" campaigns and "sandbox" campaigns as if they are opposite choices. I don't think this is entirely accurate. In any case, there is a third alternative that is probably my favorite: the "Yam-Shaped Campaign."

A "Yam-Shaped Campaign" is "narrow at the beginning and end but wide in the middle". In other words, it has a clear beginning (possibly with clear goals) and one (or preferably, a few) explicit endings. However,  HOW and IF you'll get there is up to the PCs.

In 5e D&D, Tomb of Annihilation (ToA) and Curse of Strahd (CoS) are good examples. In B/X, my favorite is probably B10 Night's Dark Terror.

Instead of adding a picture of a yam to this post, let's try this.

The PCs start the game at point A, in an exact place and time. Although this might seem to be the case for all campaigns, it is not. For example, if you're running a random wilderness, the PCs might be in a world of quantum randomness.

Points B and C are two possible "endings": let's call them the good ending and the bad ending.

In this kind of campaign, the PCs will usually have, at the very least, a vague idea of B or C. Conversely, they might have a vague idea (or a few options) on where to go NEXT and they eventually find out about B or C as the campaign progresses.

The black lines represent the multiple paths the PCs can take. The grey lines represent possible paths that lead the PCs away from the proposed ending.

Let's try some concrete examples.

In Curse of Strahd, the PCs begin near the village of Barovia. They know one possible "bad ending": they get stuck in there forever. This is unlikely to actually happen, because both the PCs and the villain are unlikely to sit and wait. So they have a clear goal instead: get out of there.

With that in mind, they can wander around looking for an exit, and they'll eventually realize that the only way to do that is to face Strahd. This is "point B". When they face Strahd, they can defeat him, join him, replace him, etc. 

The book even contains a page describing what may happen next, but this is beyond the scope of the campaign. Having this is very common and useful, because you might want to continue playing after Strahd has been "resolved".

In the diagram above, I used "time" as an axis. This can be some type of "STRICT TIME RECORD" or something more abstract. Strahd has no clear timeline, but the confrontation gets closer and closer. Tomb of Annihilation has a strict time limit: if enough time is passed, the PCs simply fail and everyone is doomed (IIRC).

Both approaches are possible, but I think SOME time pressure is needed in this type of campaign or the PCs might wander around aimlessly.

In any case, there is at least two possible endings; probably more. I think of point B as some kind of "final showdown" that can result in victory or tragedy (C).

Even if the "endings" are clear, the GM might have to choose what to do if they are skipped. What happens if there is a TPK, for example (all PCs die?). Do they start again with new PCs? Turn back time? Find a new campaign? Or maybe advance the time line a few years, and create PCs that must serve/oppose the (now victorious) antagonist?

What if the PCs leave the continent or ignore the villain? Same thing. Most decent campaigns will at least give you an idea on what to do next, but you're mostly on your own.

When I wrote my own adventure, I didn't know this "Yam-Shaped Campaign" terminology. But I did include an "aftermath" section that I'll add here as an example, as it includes:

- Two possible "boss" endings.

- What happens if the adventurers just fail or leave.

- Ideas for more adventurers if they succeed.

These three possibilities are the bare minimum, I think, to include in a yam-shaped campaign. Here is how it looks:

Aftermath

Here is what happens after the end (or in the middle, in some cases) of the adventure.

If Malavor is slain, the bee-people will immediately destroy the remaining demons. The Queen (now free from mental slavery) will telepathically ask the adventures for death, but she will resurrect from its own carcass (as an ordinary bee) in less than one minute and fly away. The fortress will collapse within 1d6+6 days. The demons in the underground will be buried alive. Some might survive.

If the Queen dies, bee-people will disperse immediately. It will take Malavor 3d6 days to summon another avatar or come up with a new use for his fortress. His success is not guaranteed. He might try a different plan. In any case, the hive will still be a menace as long as Malavor lives.

If both the Queen and Malavor are still alive, the hive expands. In 2d4 weeks, the number of demons and bee-soldiers is doubled, and the hive’s defenses are reinforced. In another 1d6 weeks, Malavor manages to mutate himself into a bee-demon, half-insane, but with full control of the bee-people. The bloated and sick avatar dies after a while, but this no longer affects the bee-soldiers, that can now be cloned in the underground. Three months after the characters left, Malavor unleashes his army against the nearest village.

The underground is a different matter. The underground is currently running its own schemes. It supports Malavor but only because he lets them do their own stuff. If Malavor leaves the hive, they will quickly take it. They will seal all doors to the outside, leaving a couple of secret passages. They might demolish the towers to avoid getting attention from the outside, and cover the whole fortress in dirt to transform it into a mound. They are digging their own underground tunnels, leading to somewhere miles away… or miles below. There are more demons in the Abyss that spawned Malavor and the biomancers.

In addition, unless Zothaq and more than half the biomancers working underground are killed, the underground keeps expanding until it becomes some kind of megadungeon, full of demons and hybrid life forms. The forest around the ruins of the hive becomes progressively weirder, with mutant beasts prowling around. Fortunately, they have no plans of conquering neighboring towns right away (the idea here is that the characters find this out and come back after a while, hopefully when they are a bit stronger).

In conclusion, I have run multiple campaigns. Some could be described as "Railroads," others as "sandboxes," but lately, I have realized that Yam-Shaped Campaigns are my favorites. 

In my sandbox campaigns, I have noticed that the PCs (Player Characters) often get lost easily and have no clear direction. As a DM, I then have to decide abruptly where the game should end, or I let it fizzle out. Conversely, railroad campaigns feel terrible: it is like the PCs have no choice and I have the sole responsibility of taking the game to the end.

Yam-Shaped Campaigns give me the best of both worlds: the PCs are free to wander around and surprise me, but I always have an idea about what is going to happen next and we can even have an epic  - or tragic! - ending before moving on.

Tehanu, A Maze of Death, Fouché, White Nights, Sacculina (micro reviews)

Here are some very short reviews of some books I've read lately. The one-sentence summaries (in italics) are not mine, but copy-pasted from AI to save you a few clicks.

I gave each book a rating, but to each might have been influenced by my expectations - so my judgement of Dostoevsky (one of my favorite authors) is probably a lot harsher than Fracassi, which I haven't read before. Highly subjective, of course.

I avoided the number 7 because it is too easy to choose 7 when you're unsure, so I forced myself to choose between 6.5 and 7.5 when that was the case.

Tehanu by Ursula K. Le Guin (rating 5/10): This fourth book in the Earthsea series follows the story of Tenar, now a middle-aged widow, and her journey of self-discovery and empowerment. 

I really like LeGuin and I'd recommend everyone to read A Wizard of Earthsea. However, Tehanu almost bored me to tears. There is little to no action. By the end of the book the protagonist meets failure because... she cannot get the lord of the land to help with the dishes.

It's curious because "From Elfland to Poughkeepsie", another text I really like by the same author, seem to point in the exact opposite direction: making fantasy fantastic, not mundane.

Anyway. Read A Wizard of Earthsea and keep reading until you stop liking it. Books 2 and 3 are decent, but the first is my favorite. This fourth book is probably for hardcore Earthsea fans only, and it will not please them all.

A Maze of Death by Philip K. Dick (rating 6.5/10): A complex and thought-provoking sci-fi novel where a group of colonists on a distant planet must unravel the mysteries of their existence. 

Far from my favorite PKD novel, still interesting in the exploration of themes like religion and shared realities and fantasies. As it often happens with this author, his vision still looks relevant decades later. The ending is... very peculiar to say the least, but maybe not great.

If you like PKD, you'll probably enjoy it.

Fouché: The Unprincipled Patriot by Stefan Zweig (rating 9/10): This biography of Joseph Fouché delves into the life of the cunning and enigmatic French politician who navigated through the turbulent times of the French Revolution and Napoleonic era. 

Such an awesome book! A short, fun read for anyone, and it is also full of ideas you can use for your role-playing games. His story is full of war, intrigue, violence, and backstabbing. Fouché is an amazing character - he would make an amazing villain or patron - maybe both!

Of course, if you are interested in the French Revolution, this is a must read.

(Sidenote: Zweig also wrote a Dostoevsky's biography that I didn't enjoy as much and will not review).

White Nights by Fyodor Dostoevsky (rating 6.5/10): A melancholic yet hopeful tale of a lonely dreamer who falls in love with a mysterious woman over the course of four nights.

This is one of Dostoevsky's earliest works. I have never read anything bad by Dostoevsky. This is not his best, but already shows some signs of an author who would soon become one of the greatest (if noyt the best). It reads like a silly love story at first but manages to get deeper as you go.

Overall, a short, enjoyable read.

Sacculina by Philip Fracassi (rating 7.5/10): A gripping horror novella about a group of friends who encounter a terrifying and parasitic creature while on a fishing trip. 

A pleasant surprise! This is a decent horror novella by an author I didn't know. Reads like an exciting good script for an one-hour movie. A quick, exciting read.

It has echoes of H. P. Lovecraft and Algernon Blackwood ("The Willows"). If that is what you like, you'll probably enjoy this one.

More glancing blows (and near-saves)

 A quick rule for any D&D game. I'm certainly not the first one to suggest the "half damage" part.

---

Glancing blows

When you roll the exact number needed to hit the target's AC, this is a glancing blow.

You damage is halved.

If the target has more than 1 HP before the hit, the glancing blow can reduce it to 1 HP, but no less.

---

This is the gist of it, but we could change the specifics. 

Instead of half damage, for example, I might do "one third of your maximum damage" to save myself a roll (and further differentiate 1d6+1 from 1d8 damage). 

Likewise, the "1 HP" part probably needs a few exceptions, but it would be fun if even a peasant has a 5% chance to survive being hit by a powerful monster and live to tell the tale (even if unconscious, maimed, etc.  -the idea is that a glancing blow doesn't kill).

You could extend the same reasoning to saving throws. This is somewhat similar to what I've been doing in my games. When the MU casts an 8d6 fireball, I make a roll even if the target is a group of goblins, allowing a natural 20 to save some of them. I might call this rule "there is always a save".

D&D 4e had minions rules that worked in a similar way: "minions" had only 1 HP but wouldn't be killed if they made a successful save. 

I think my version feels a bit less artificial. No goblin should resist TWO 8d6 fireballs! Also, REDUCING a foe to 1 HP is a great opportunity of surrender, retreat, parlay, etc.

I also like making glancing blows a common concept so my players can finally accept I'll eventually tell them the monster's AC, so they might as well stop asking if they hit!

Anyway, for now this is just a random thought.
