Martyrdom ability: 500 range unit-targeted ability on the Zealot creep, targeting either an enemy or ally unit. When cast, the creep sacrifices itself, firing a projectile at 1000 speed at the target unit, dealing damage if it's an enemy or healing if it's an ally. Damage is 25 + 20% of the Zealot's health at the moment of the cast, and healing is 50% of these values
