Developer Comments:
When an enemy minion dies, it will drop a coloured potion, showing you which reward Ruffles will go to collect.
Ruffles jumps off the tower, and runs to the potion, spending a moment to pick it up. If he takes any damage he will retreat and the potion disappear.
Upon acquiring the potion, Diona will gain the benefit, and Ruffles will enter the “unready” state on the Tower for 10 seconds. His cooldown if you will.
