Ability Haste

Reduces ability cooldowns.

Quando você precisa

Mages & bruisers for rapid spell rotations.

Formula: reduction = AH / (AH + 100). 100 AH = 50% CDR.

Dodge their key skillshots — if they whiff, AH doesn't help. Build MR/Armor for extended trades.

Mages (Lulu, Lux, Karma) and supports, Spellblade fighters (Sett, Riven).
