Unofficial Advanced Dungeons & Dragons Players Handbook

A compilation of house rules for an early fantasy role-playing system, revising character creation, combat, races, classes, and equipment. Armor class starts at 10 and increases with better protection, with attack rolls adjusted to match. Initiative is resolved by segments, and movement and weapon ranges are given in feet rather than inches. Human characters can multiclass, while demihumans have no level restrictions. Additional playable races and classes are included, along with a revised bard presented as a thief subclass. Alignment language is removed, and class restrictions and multiclass options are more clearly defined.
