The AC/DC Hack

This is a rules-light OSR framework where AC (armor class) doubles as DC (difficulty class) for all checks, not only in combat. The more worn down by armor, the harder it is to pull off awesome feats.

Features:

• Quick, gear-centric character creation
• one-column rules for checks, saves, combat, spellcasting and recovery
• 20 spellbooks
• Bestiary guidelines
• D66 tables to keep things fresh

Made for the One-Page RPG Jam 2026.
