Willo item
Willo is an unlockable familiar in Revelations, a mod for The Binding of Isaac.
Description
Grants a familiar that bounces around the room diagonally and has a purple aura around it.
Being inside the aura grants Isaac homing tears and ×1.3 damage multiplier, and also acts as a warming aura in frozen rooms.
The familiar very slightly moves away from Isaac when approached.
When Isaac takes damage, Willo shoots 5 homing spectral tears at the enemy that hurt him.
Willo will shoot at anything that is a valid entity, including 
Blood Donation Machines. It can even shoot at Isaac if he takes self-damage, but won't actually damage him.
The damage of Willo's tears is equal to DamageStat - (DamageStat - 3.5) × 0.5.
How to unlock?
Activate a 
Pact of Frost.
