Channel Stench

''You draw in a deep breath and expel it towards your opponents. Noxious odors are channeled through your breath and ejected in a vile cone of stench.''

All breathing creatures within the cone must make a Fortitude save. Those who fail become nauseated for 1d6 rounds. Those who succeed instead become sickened for 1d6 rounds. Creatures with 5 or more Hit Dice are immune to this effect.
