Something based on Evard's black tentacles, upsized a bit.
Conjuration (Creation)
Level: Sor/Wiz 8
Components: V, S, M
Casting Time: 1 standard action
Range: Medium (100 ft + 10 ft/level)
Effect: Wall of tentacles whose area is up to one 5 ft square/level (S)
Duration: Permanent
Saving Throw: See text
Spell Resistance: No
You call into existence a wall of pitch black darkness. The wall blocks line of effect and line of sight, but only in one direction; it is translucent and transparent to spell effects and physical attacks in the other direction. Tentacles lash out from the wall and automatically grapple any creature that approaches within 10’, except for those designated by you (see the hallow spell for how to designate creatures). The wall’s grapple check bonus is equal to your caster level +14. A successful grapple inflicts 3d6 points of damage on the grappled creature. Further, any creature grappled for 3 consecutive rounds must make a Reflex save or be dragged into the wall, where it automatically takes 5d6 points of damage each round.
The wall is immune to all types of damage, with the exception that a disintegrate stops it grappling for 1 round. It cannot be dispelled, but a break enchantment or limited wish will destroy it.
Material component: a black pearl worth 500 gp.
