At 10th level, a stygian slayer can transform into an inky black cloud of mist. This ability functions as gaseous form, except it also obscures vision as fog cloud. The slayer can use this ability for a number of minutes per day equal to his level. The duration does not need to be consecutive, but must be used in 1-minute increments. This ability replaces the advanced slayer talent gained at 10th level.
