The interdimensional strangler's spellcasting ability is Charisma (spell save DC 18, +10 to hit with spell attacks). It can innately cast the following spells, requiring no components: • At will: detect thoughts, dimension door, plane shift, ray of enfeeblement, scrying
A creature grappled by the tentacles of the interdimensional strangler is prevented from changing its location by using any means of dimensional movement, teleportation, or planar travel.
The interdimensional strangler can see and hear a particular creature that it is targeting with a scrying spell even if the target creature is not on the same plane as the interdimensional strangler.
The interdimensional strangler can extend its tentacles into any location that it has already seen. This location can be on any plane of existence. The interdimensional strangler can attempt to drag a huge size or smaller creature that it has grappled over to the place it currently inhabits, even if the target is on another plane of existence. A creature pulled through the dimensions this way must succeed on a DC 19 Strength saving throw. On a failed save, the creature is pulled from the other dimension and appears within 20 feet of the interdimensional strangler. When reaching to another plane and being separated from its body, a tentacle has AC 12 and 20 hit points. Any nondamaging spell or effect that targets the tentacle also targets the interdimensional strangler. Whenever a tentacle's hit points reach 0 hit points it is severed and the interdimensional strangler takes 10 hit points of damage. At the end of its turn, the interdimensional strangler grows a tentacle to replace the tentacle that was severed since its last turn. The interdimensional strangler regains 10 hit points for a tentacle regrown this way.
The interdimensional strangler has advantage on saving throws against spells and other magical effects.
The interdimensional strangler makes three tentacle attacks.
Melee Weapon Attack: +11 to hit, reach 20 ft., one target. Hit: 13 (2d6 + 6) bludgeoning damage, and the target is grappled (escape DC 16). Until this grapple ends, the target is restrained. The target creature must succeed on a DC 18 Constitution saving throw or be paralyzed for 1 minute. The target can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success. The interdimensional strangler has six tentacles, each of which can grapple one target.
