Urn of Shadows

Provides 30 health regeneration when cast on allies, and deals 25 damage per second when cast on enemies. Lasts 8 seconds. If the unit is attacked by an enemy hero or Roshan, the effect is lost. Gains charges every time an enemy hero dies within 1400 units. Only the closest Urn to the dying hero will gain a charge.

Empty urns gain 2 charges. If used on a hero with Soul Release already active on them, it will refresh its duration. Does not trigger spell block or spell reflect.
