A flumph can spray a 20-foot line of foul-smelling liquid every 1d4 rounds. This spray functions like the stench universal monster ability, except it only affects creatures struck by the spray, which must make a Death save or be sickened for 5 rounds. Alternatively, the flumph can concentrate the spray on a single target within 5 feet. To use this version of its stench spray, the flumph must succeed at a ranged attack. If the target is hit, it must make a save or become nauseated for 5 rounds; otherwise, it is sickened for 5 rounds. The odor from this spray lingers in the area and on all creatures struck for 1d4 hours, and can be detected at a range of 100 feet (creatures with the scent ability can smell it at double this range).
