Well I was thinking it'd be an immediate infliction on all enemies, not something based on being hit by a basic. At that point, it's not really going to do much of anything since most basic attackers don't do large AoEs. Infliction chance upon taking any damage from someone, however, would be fine IMO.

EDIT: Maybe even infliction chance for hitting any of your allies. Because why not.

EDIT 2: I just realized after re-reading that you probably meant on the Papilion's basics, not the enemy's. This is why I shouldn't be allowed to multitask. Either way.
