Anti-Plant Shell

The anti-plant shell spell creates an invisible, mobile barrier that keeps out all creatures or missiles of living vegetable material. Thus, the caster (and any creatures within the shell) is protected from attacking plants or vegetable creatures such as shambling mounds or treants.
Any attempt to force the barrier against such creatures shatters the barrier immediately.
