Smite (Tier 0)

Smite (Tier 0) is obtained as a drop from each faction's minions in the Battle of Lumbridge. A player can "Drink" this item and it is used immediately one time to hit 20% of the target's maximum health in damage.

Instead of dealing the damage instantly, it seems to hit for 4% of maximum health 5 times over 3 seconds, in non-ability magic damage.
