Lulu's E ability bugged

Its her w that polymorphs 😊

Lulu's E is NOT a polymorph, her W is.

Perhaps you are a bit confused since Lulu's W and E have differing effects based on whether or not you cast them on allies or enemies.

When cast on ALLYS: W - Gives move speed. E - Gives a shield

When cast on ENEMIES: W - Polymorphs them (they cannot attack or cast spells) E - Does damage, and gives vision
