Gonna work on a post this weekend, don't worry
The system is quite simple: the Attack and Defense stats are used in combat as a 1d A vs 1d D. If attacker hits, deals 1d A damage.
The classes give various bonuses to Attack and Defense, or spells.
Strength, Agility and Mental are in case of puzzles requiring attributes: 1dx vs a set difficulty class.
I'm gonna update the ruleset soon too (I have loads more changes needed to balance the classes).
EDIT: Initiative increases your place in the turn order, and Stealth covers how hard to detect you are, and how much extra damage you deal if you perform a sneak attack.
Tiamat, you DO have one spell. Blinding Flash, look it up in your character sheet.
