Blindsight: 120 ft (blind beyond this radius)

Acidic Blood. A creature that deals bludgeoning, piercing, or slashing damage to the xenomorph while standing within 5 feet of it must make a DC 15 Dexterity saving throw, taking 14 (4d6) acid damage on a failed saving throw, or half as much acid damage on a successful one.

Biomechanical Camouflage. The xenomorph has advantage on Dexterity (Stealth) checks made to hide in mechanical and industrial terrain.

Echolocation. The xenomorph can’t use its blindsight while deafened.

Pack Tactics. The xenomorph has advantage on an attack roll against a creature if at least one of the xenomorph’s allies is within 5 feet of the creature and the ally isn’t incapacitated.
