A high level caster could effectively encircle a small city with such a wall, should she choose. The wall rises to a height of only ten feet, but is extremely effective in keeping land based creatures out. The roses are unaffected by non-magical burning, Any creature trying to force or hack it’s way through the roses will take 2d10 +1 per caster level points of damage to do so, as the vines tend to swing when disturbed and it is impossible to protect oneself against them. It takes 1d3+1 rounds to wade your way through the wall. Note that the wall will snake it’s way around pedestrians when forming, so you can not simply cast this spell onto an opposing army, slaying them all in one fell swoop.
The material component of this spell is a single live rose blossom.
