Any Dota players?

Starts with 0 charges. Each time an enemy hero dies near you, it gains a charge. The first charges increments by 2, so it goes 0/2/3/4/5/etc

Each usage of the item decreases the charge by 1.

Each hero death can only charge up one of these items per death, so more than one hero having this will not increase the charges for both of the items.

Can be cast on an ally to heal, dispels on non-creep damage. Can alternatively be cast on an enemy hero to do half the heal (200) as damage over 8 seconds.
Heal: 400 HP over 8 seconds
