Miasma and Monsters is a TTRPG inspired by the Knave hack, Glaive, but it is its own game entirely. It offers a class-less system that lets players customize their character as they advance in levels. It should be compatible with any Old School content with some light conversion.
There are two major elements that make this game unique:
Class-less characters that are created by picking Traits when leveling up
Rules for spreading Miasma within an existing world, spawning Sources of Evil, creatures with mutations, and adding instant exploration sites for the party
