Sharp Swords & Sinister Spells Automatic Monster Generator

I'm currently playing in a science fantasy game run by z_bill and we're using this cool, OSR-like system called Sharp Swords & Sinister Spells (hereafter referred to as SS&SS). The SS&SS Addendum includes a cool monster generator, and this is an automatized version of that generator. Both books are available for PWYW so I hope they don't mind me making this available publicly, but if not I'll pull it down. Hopefully people find this useful and it draws attention to this cool game. I may create a follow-up to this if it's well received, but for now it's a mostly straight translation of the generator from the book, which I would strongly encourage you to buy! If this post encourages you to check out the game, please comment below!

Note that some of the text refers to mechanics specific to SS&SS, but most of it can be easily converted to OSR or other systems. For instance, positive/negative die just means roll twice and take the better/worse result.

Generate Creature

Note that I have removed amalgam options and certain other options from the autogenerator for the time being but they are in the below tables. Additionally, the book lists a 'Mythological' Nature but I'm not finding it in the book, either because I'm going crazy 0.o or they forgot to include it or forgot to remove it, so I have added my own set of Mythological Characteristics.

  1. Great job integrating all of this stuff, you've definitely outdone yourself here

    1. Thanks! This is definitely the most involved HTML/javascript project I've done yet, although largely due to the sheer size of the tables than the complexity per se. If I have time I'd like to add in the amalgam options but that's just going to be a huge pain to code, even though I don't think it would be that complex per se :/. Anyway I'm hoping to use this as a skeleton for future projects, we'll see...

  2. I can't believe I haven't seen this before. This is great stuff!

    1. Sharp Swords & Sinister Spells is a great game :). I've got various other generators from other games, like Hubris, and also plenty of my own stuff on this blog.
