Companion abilities
AI-controlled party members have their own distinct skills, spells, or combat roles that the player can trigger, combine with, or rely on independently. Mass Effect 2's squadmates each bring a unique power (biotic pulls, tech overloads) that synergizes with the player's own kit, while Dragon Age: Origins builds tactical depth from managing a full party's ability rotation. Designers use companion abilities to expand the tactical toolkit beyond what one character could hold, to make party composition a strategic choice, and to give each companion mechanical identity alongside their narrative one. Key decisions: how much direct control the player has (issuing commands versus autonomous AI), ability synergy design (combos across companions), whether companions can be built/customized or are fixed, and AI competence (a companion who uses abilities badly undermines the whole system). Pitfall: companion AI that wastes abilities or acts unpredictably erodes trust — players need to be able to predict or direct what their allies will do.
