Components: V, S
Casting Time: 1 standard action
Range: 10 ft.
Area: 10-ft.-radius emanation centered on you
Duration: 10 min./level (D)
Saving Throw: None or Will negates; see text
Spell Resistance: Yes
Spell Points: 7
You create an invisible barrier to hold back vermin.
A vermin with 3 Hit Dice or less cannot enter within the radius of the emanation. This includes all swarms consisting of vermin, regardless of the swarm’s total number of Hit Dice.
A vermin with more than 3 Hit Dice can penetrate the barrier if it succeeds on a Will save. Even so, crossing the barrier deals the vermin 2d6 points of damage, and pressing against the barrier causes pain, which deters most vermin.
Augment: For every 2 additional spell points you spend, the emanation prevents the entry of creatures with one additional Hit Die, and the damage dealt to higher HD vermin who manage to cross is increased by one die (d6).
