Swords & Wizardry
Complete Rulebook, RevisedCore Mechanic
Roll a d20 with attack modifiers and meet the target number for the chosen Armor Class system. Ascending Armor Class allows a direct roll against AC; descending Armor Class uses attack tables. Saving throws use a single class-based d20 target number with bonuses against particular hazards.
Best For
Groups seeking dangerous dungeon expeditions and open wilderness campaigns. Higher-level characters can establish strongholds and govern surrounding settlements.
Highlights
One class-based saving throw target replaces separate hazard categories. Treasure grants experience points, rewarding successful expeditions even when monsters are avoided. Stronghold construction and settlement taxes support campaigns that grow into territorial rule.
Considerations
Low starting hit points and death below zero make early combat dangerous. Damage during casting interrupts a prepared spell and expends it. Nonhuman ancestry restricts available classes and level advancement.
