Caitlyn enables

  • Mark

    A status the unit applies to enemies, then later spends or counts to trigger a payoff. Examples: Kindred attacks build marks on a target and Wolf consumes them at 3 stacks for bonus physical damage; Doomer marks all enemies at combat start, and the mark is consumed on first damage to steal AD/AP for the strongest Vex.

  • Empower

    Generic enhancement — temporarily boosts an attack, ability, or stat beyond its baseline. Empower effects are usually one-shot bonuses tied to a single attack or cast (e.g., Caitlyn's Headshot passive empowers a chance-based attack — 15% per shot; Vex's Active fires 3 empowered strikes), not permanent stat gains.
