WARNING: This is a Work-in-Progress.

If links are missing, it is because work isn't complete!

Octas is probably not fully-playable at this stage. It is definitely not properly play-tested for balance.

Bare with me: doing a project like this largely alone is not quick!



Octas is a Table Top Role-Playing game system based on the use of two 8-sided dice, numbered 0-7. It ostensibly uses the octal (base-8) numeric system, although this is largely hidden from players behind some simple conversion maths. It also uses a 'destructive stats' mechanic whereby combat damage temporarily (or in extreme cases permanently) reduces character scores directly, resulting in a game mechanic representation of fatigue.

A playable base game is available for free use here. Hard-copy books and related accessories are unlikely as I don't expect that amount of interest in my downright-quirky little TTRPG!
