Wall of Tentacles

Effect: You spend approximately 1 hour adorning the floor and adjoining walls of the area with sigils drawn in Kraken Ink. At the end of this time, you lay the Kraken tentacle at the center of the area and begin to chant. During this time, the tentacle swells, growing until it creates a wall of fleshy, writhing tentacles.

You create an animated, fleshy wall of tentacles to serve as a barrier. Creatures you designate at the time of casting (which could broad such as a particular race or a specified list of creatures) can pass through the wall unhindered, as if traveling through a viscous, pudding-like substance. All other creatures will encounter a solid wall that will animate once touched or attacked. The animate wall functions as the simple monster below, grasping and attacking all creatures within its reach. Once activated, the wall will continue to flail and grasp until it is destroyed, dismissed by you, or 1 phase have passed without an attack or touch from an undesignated creature.
