Massacre is an ultimate Attack ability. It requires level 66 Attack to use, and for the player to be dual-wielding weapons. It has a cooldown of 60 seconds. When activated, the player deals 37.6-188% of ability damage to their target and causes the target to take additional damage over 6 seconds, dealing 5 hits of 62.6% ability damage (313% ability damage total). Massacre is one of five bleed abilities for the Attack and Strength skills, the others being Lesser Dismember, Dismember, Slaughter, and Blood Tendrils.

Unlike most abilities, the bleed damage caused has no damage range - it is always 62.6%, regardless of what the first hit is. This makes the overall damage range of the ability 350.9-501.3%, average 426.1%.

Unlike normal abilities, damage over time effects are not affected by:
Damage boosting prayers and ancient curses (aside from their accuracy bonus)
Damage boosting abilities: Berserk, Death's Swiftness, and Sunshine (with the exception of Metamorphosis)
Zaros Godsword's special attack
Berserker's Fury relic power
Most invention perks affecting variable damage, including Genocidal, Precise, Equilibrium, and Ruthless
Some items from the slayer (effect) groups, including: tuned Bane equipment, Salve amulet (e), Demon slayer equipment, Darklight
Critical hits
Slayer helmet and its variants

Damage over time effects are only affected by some modifiers, including:
Damage bonus from equipment
Visible combat skill boosts, from potions or other sources
Vulnerability or its lesser form, Curse
Berserker, Reckless, and Maniacal auras - however, while inside the effects of Berserk, Death's Swiftness, or Sunshine, the aura's invisible boost is negated
Mahjarrat and Dark magic auras - regardless of being inside the effects of Berserk, Death's Swiftness, or Sunshine
Among the Dragon slayer, Demon slayer, and Undead slayer effect groups, only the slayer invention perks and slayer abilities affect bleeds
Scrimshaws
Icy Precision effect granted by Wen arrows

The ranged equivalent of this ability is Deadshot; however, Deadshot does not require the player to dual-wield weapons and is unlocked at a much lower level, and additionally only has 30 seconds cooldown instead of 60 seconds.
