Diversion

Description
For 6 seconds, the next time target foe uses a skill, that skill takes an additional 10...47 seconds to recharge.

Usage Notes
Diversion does not prevent the skill from being executed, it just dumps additional recharge time on top of the skill's innate recharge time. Which means that if you can catch enemy Healing-Spamming monks ( as if most enemy monks don't spam heals...), Diversion can kill off Orison of Healing for a good amount of time, minimum 11 seconds. 11 seconds is all you need to slaughter the enemies.
