You finish the spell, and a burst of fog appears among your enemies. Tendrils of the gas seem to cling to them and seek out their mouths and nostrils.

The spell produces a toxic fog that deals 3d4 points of nonlethal damage. Creatures in the area that hold their breath are still subject to the effect. Creatures that are immune to poison are not affected by this spell.

Any creature which takes damage is disoriented for 1 round.

Augmentation:
