Description: A field of thick, 10 foot long rubbery tentacles rises from the ground. Each is capable of grappling a target doing CLd3 Bludgeoning damage. Tentacle AB is (5/6 CL) + (caster modifier / 2) + (Conj foci * 3). If successful, the target must then make a fortitude saving throw or become paralyzed by the grappling tentacle.

Notes

The tentacles are randomly spread out over the area of effect allowing no more than half of the tentacles to reach a single target in any given round. The inability of the tentacles to target small creatures makes all small creatures completely immune to the spell's effects.
Though this spell is not mind-affecting, immunity from mind-affecting effects still blocks the paralysis.
This spell can be devastating when used in conjunction with the empower spell feat. This is because the 50% bonus applies to both the number of tentacles from the die roll and the number of tentacles deriving from caster level, as well as applying to the damage each dealt by each tentacle.
