Causes a deadly gas to form over the target area, dealing 1d4 CON damage/round and bestowing deathwatch for 2d3+1 rounds. Targets who already have deathwatch must make an additional death save or else collapse. No effect on unliving targets. If caster has greater spell focus: conjuration, instead lingers for 3d3+1 rounds. Like all gases, it will be dispersed if any part is affected by gust of wind.
