B/X random encounter/travel generator

So I've made a small dice roller / random encounter/ travel generator for B/X, OSE and other "Basic" games.


This is a tool I wanted to have for my own games; I realized it takes too long to roll during the game. Now I can do most of the work with a click (or a few clicks; see below).


I've tried several solutions, including rolling 1000 (!) encounters for my games, many of which I used with great success - they are in the Basic Wilderness Encounters book.

But I also wanted an automated tool for weather (I often forget to roll/describe it) and encounter checks. The weather checks are just descriptive unless they roll terrible weather. I created them inspired by the reaction table.

This isn't as complete as Basic Wilderness Encounters (which also includes NPC names, number and type of monsters appearing, etc.). It is more agnostic, however; you can combine it with your favorite random encounter table, table of random names, etc.

Here are some fine tools for OSE. I've seen some other tools out there in the format of apps and spreadsheets, but I prefer having one link, that I can "roll" with one click.

And it is very transparent, you can ignore any roll you want, add Charisma to the reaction check, let PCs roll for surprise, etc.

I might fix some stuff if I had similar tools formatted for perchance. I especially wish I had a generator that also gave me the number appearing immediately; the rest is often not as important, because the PCs can sometimes choose to ignore the encounter, for example.

I hope this tool helps you experiment running B/X or OSE encounters as originally written, taking distance, surprise, reaction, etc., into account.

This has LOTS of room for improvement, but it takes work. Anyone can edit it (give me credit if you find it appropriate), and I hope there are other generators out there which we can use, add, remix, etc. 

Please let me know! I'd love to have a good perchance generator for B/X or AD&D encounters that I can incorporate to this one!
