You uncork the vial and speak the old words. The smoke issues from the bottle and wraps itself around your hand, turning it into smoke as well.
With a successful touch attack, you deal 2d12 points of damage. For every three caster levels, the smoke lasts for another round (to a maximum of 4 additional rounds at 12th level), dealing another 2d12 points of damage per round.
