Wall of Crabs (3.5e Spell)

''I've got a big wall of crabs here! I'm gonna trap you in their grip, oh yeah! I'm gonna cast this spell around on market day! Everyone look at me and see my really big wall of crabs!''

This spell creates a swarm of crabs stacked on top of each other and crawling all over each other, providing a semi-solid barrier to entry and a danger to those passing near or through it as their sharp legs and pinching claws tear at open flesh. Any creature forced into or attempting to move through the wall of crabs takes 4d6 of magic slashing and piercing damage (Reflex negates) from the supernatural crab swarm, and their movement is reduced to 5 feet a round (no save on the speed reduction). freedom of movement negates the speed decrease, but not the damage.

The crabs are also actively hostile to enemy creatures standing nearby. They threaten out to 5 feet in range, and creatures which provoke an attack of opportunity must make a Reflex save or take 4d6 damage, save negates.

You can make the wall as thin as 5 feet thick, which allows you to shape the wall as a number of 10-by-10-by-5-foot blocks equal to twice your caster level. This has no effect on the damage dealt by the crabs, but any creature attempting to break through takes that much less time to force its way through the barrier.

Any creature within the area of the spell when it is cast gets a Reflex save. If successful they move to a square not inhabited by the wall.

The wall of crabs has 10 hp per caster level and AC 10. It takes half damage from piercing and slashing damage. They remain immobile where they are. However if cast underwater and the wall is dispelled or a portion is destroyed, the wall will reform 1d4 rounds later. Despite its appearance, a wall of crabs is not actually a living creature, and thus is unaffected by spells that don't deal hp damage.

Material Component: A empty crab claw.
