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.

Actions

• 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.

ABOUT

Trappers are thought to be distant relatives of the lurker above. Unlike their relatives, however, trappers mimic the floor of a building, dungeon, or other structure. By manipulating their body structure while covering the floor, trappers can form a box that resembles a small trunk or chest. This is usually enough to lure would-be-adventurers to their doom.
