Dungeons & Dragons 3.5 Edition
Version 3.5Core Mechanic
Roll a d20, add relevant modifiers, and compare the total to a target number. An equal or higher total succeeds. Ability checks, skill checks, attack rolls, and saving throws use this framework. Combat uses initiative and defined action types, while damage dice are rolled after a hit.
Best For
Groups running fantasy campaigns that want class-based character advancement, prepared-spell resource planning, and position-sensitive combat. It also supports GMs who want encounter construction, monsters, treasure, and campaign procedures in the core set.
Highlights
Class levels, skills, and feats create distinct mechanical advancement paths for characters. Grid combat combines initiative, movement, action types, attacks of opportunity, and special attacks into positional decisions. The Dungeon Master's Guide and Monster Manual supply encounter, campaign, and creature-construction procedures alongside player rules.
Considerations
Character creation requires choices across race, class, ability scores, skills, feats, equipment, and spells. Spellcasting uses separate class lists, spell levels, daily spell counts, and preparation rules. Encounter design requires the GM to reconcile challenge ratings, creature statistics, treasure, and adventure procedures.
