Basic attacks and basic ability casts generate 1 and 2 stacks of Anticipation for the rest of the round, respectively, stacking up to 40 times. For each stack, increase your ultimate ability's damage by 3% and gain 2 ultimate haste, up to 120% increased ultimate damage and 80 ultimate haste.

Anticipation stacks multiplicatively with other sources of damage amplification.
Anticipation's stacks are gained at the start of a cast time.
