@Willbachbakal: For such cases there are two options, in both cases the effect is applied either On-Hit (Be this on a autoattack or an active ability that applies on-hit effects) or an ability.


 * An effect with a static cooldown that decreases its cooldown by a certain amount for a specific condition, commonly basic attacks but could be aswell by spells, instances of damage or a specific kind of CC.


 * An effect with a static cooldown that is applied once per a certain amount of casts.
