Special Traits

  • False Appearance. While the trapper is attached to a ceiling, floor, or wall and remains motionless, it is almost indistinguishable from an ordinary section of ceiling, floor, or wall. A creature that can see it and succeeds on a DC 20 Intelligence (Investigation) or Intelligence (Nature) check can discern its presence.
  • Spider Climb. The trapper can climb difficult surfaces, including upside down on ceilings, without needing to make an ability check.


  • Buffet. Melee Weapon Attack: +12 to hit, reach 10 ft., one target. Hit: 18 (2d8 + 9) bludgeoning damage.
  • Envelop. One Large or up to 4 medium creatures within 5 feet of the trapper must succeed on a DC 15 Dexterity saving throw or be grappled (escape DC 15). Until the grapple ends, the target takes 17 (4d6 + 3) bludgeoning damage plus 3 (1d6) acid damage at the start of each of its turns. While grappled in this way, the target is restrained, blinded, and can’t breathe.
