Bunny Prime Ballista enables

  • On Cast

    This effect triggers the instant a unit casts its ability. Items like Lich Bane and Innervating Locket reward you for landing as many casts as possible.

  • On Takedown

    Effect fires when a unit secures a kill or assist. In Set 17, Kai'Sa's passive "On takedown, gain 10 mana" is a clean example, and Seeker's Armguard stacks +20 Armor / MR / AP per takedown.

  • Crit

    Scales with crit chance and crit damage from items like Infinity Edge and Jeweled Gauntlet. By default abilities cannot crit — the sibling Precision mechanic is what lets spell damage roll crits, so crit-on-spell builds need a Precision source before crit chance and crit damage actually apply to abilities.

  • Precision

    Keyword reworked in patch 17.1. The first Precision source on a unit still flips the unlock that lets ability damage roll critical hits; every additional Precision source after that grants +10% Damage Amp instead of the +10% Critical Strike Damage it used to give pre-17.1. Sources include Infinity Edge, Jeweled Gauntlet, the Fateweaver trait innate, and a few crit-focused augments — layering them stacks Damage Amp under the new rule.
