Interrupt abilities
Abilities that stop an enemy's action mid-cast — canceling a spell, stunning a channel, silencing a caster — turning timing and target prioritization into an active combat skill. World of Warcraft's interrupt rotations in raid healing checks and Final Fantasy XIV's tank-and-DPS interrupt assignments both make 'who interrupts what, and when' a core coordination puzzle in group content. Designers use interrupts to create readable, punishable enemy telegraphs (a cast bar you can react to), to reward attentiveness and communication in groups, and to give otherwise-passive damage dealers proactive defensive tools. Key decisions: interrupt cooldown length (frequent enough to matter, rare enough to require prioritization across multiple threats), whether interrupts lock out the school of magic interrupted or just the current cast, telegraphing clarity (visible cast bars and audio cues), and diminishing returns to prevent chain-interrupt-locking a boss into never acting. Pitfall: interrupts on abilities with no visible telegraph feel like guessing rather than skill — the whole mechanic depends on the interruptable action being clearly readable in advance.
