  • Pack Tactics. The arachnomorph has advantage on attack rolls against a creature if at least one of the aberration’s allies is within 5 feet of the creature and the ally isn’t incapacitated.
  • Spider Climb. The arachnomorph can climb difficult surfaces, including upside down on ceilings, without needing to make an ability check.
  • Spider Silk. The arachnomorph can attach one end of sticky silk thread to a wall and lower itself at a speed of its choice, from 0 to 50 ft. The silk thread cannot extend further than 150 ft.


  • Multiattack. The arachnomorph makes two slam attacks, or one slam and one tentacle attack.
  • Slam. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 8 (2d4 + 3) bludgeoning damage.
  • Tentacle. Melee Weapon Attack: +5 to hit, reach 10 ft., one target. Hit: 5 (1d4 + 3) bludgeoning damage, and the target is grappled (escape DC 13). Until this grapple ends, the target is restrained.
  • Acid Vomit (Recharge 5-6). The arachnomorph spews out a cone of acidic vomit in a 15-foot cone. Each creature in that area must make a DC 14 Dexterity saving throw, taking 13 (3d8) acid damage on a failed save, or half as much damage on a successful one.
