Purchasing this item gives you a clicky in your inventory that can be used to summon a pink or red heart-shaped fan onto the cursor of your current target. They can hold it in their primary hand to see one of several corny messages:
Raid With Me
U Mezz Me
Neck Romancer
Be My Pet
U Slay my <3
Lay on Hands
UR Epic!
My Erollisi
The fans also radiate tiny red heart particles. They are temporary and placeable, so the real "utility" of this item is to decorate your home or guild hall for Erollisi Day.
