Sacrifice

Sacrifice is a basic ability, one of three abilities released with the second world event, The Bird and the Beast. It is purchasable at the event with 21,000 renown and a gold event token, and requires level 10 Constitution to use.

When Sacrifice is used, the player deals up to 100% weapon damage to their target regardless of protection prayers, and is healed by a quarter of the damage dealt, or 100% if the target dies.

Sacrifice is a basic ability, but it only gives +2% adrenaline when used.

Because it's an ability with a 30 second cooldown, the Warpries of armadyl and the Warpriest of bandos armours can shorten the abilitys cooldown period.

Unlike nearly all combat abilities, Sacrifice will always deal 100% weapon damage if it hits, derived from the user's damage stat. Sacrifice's consistent damage can be used by players to test the strength of damage buffs, which is a more accurate method than ability criticals, which are mildly randomized.

Trivia

 * Upon release, Sacrifice could not hit targets with Magic. This has yet to be fixed.
 * Because Sacrifice is a guaranteed 100% weapon damage, it is unaffected by Dharok or Verac's set effects. It is affected by potions, prayers, power armour, and Void Knight equipment.
