Dharculus

After a successful grab, a dharculus can try to attach its remaining tentacles with a single grapple check. The opponent can escape with a successful grapple check or Escape Artist check, but the dharculus gets a +2 circumstance bonus for every tentacle that was attached at the beginning of the opponent's turn. A dharculus's dual-plane existence provides it exceptional protection against its prey, while it is free to attack most potential victims with impunity, first by establishing a hold with a small mawed tentacle, then by bringing its otherwise intangible ethereal bite into play. Extraplanar Subtype A subtype applied to any creature when it is on a plane other than its native plane. A creature that travels the planes can gain or lose this subtype as it goes from plane to plane. This book assumes that encounters with creatures take place on the Material Plane, and every creature whose native plane is not the Material Plane has the extraplanar subtype (but would not have when on its home plane). An extraplanar creatures usually has a home plane mentioned in its description. These home planes are taken from the Great Wheel cosmology of the D&D game (see Chapter 5 of the Dungeon Master's Guide). If your campaign uses a different cosmology, you will need to assign different home planes to extraplanar creatures. Creatures not labeled as extraplanar are natives of the Material Plane, and they gain the extraplanar subtype if they leave the Material Plane. No creature has the extraplanar subtype when it is on a transitive plane; the transitive planes in the D&D cosmology are the Astral Plane, the Ethereal Plane, and the Plane of Shadow.
