Spirit Vessel Aura
Spirit Vessel is a Support item purchasable with items from the Home Shop and Secret Shop.
Heals HP over time for friendly units, and deals damage over time for enemy units. The healing effect is lost if the affected unit takes player-based damage, or is hit by Roshan. Gains a charge every time an enemy hero dies nearby. If the Vessel is empty and has no charges, it gains 2 charges instead. Only the closest Vessel to the dying hero will gain a charge.

- Total damage:
- 280 + 40% of current health
- Multiple casts on the same target will refresh the duration instead of stacking.
