Striker's Flail

Multiplicative bonus to all damage dealt — distinct from raw AD/AP because it applies after the type-specific scaling.

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.
