Bestiary 4 | Monsters | Devil | Drowning | Special Abilities | Heavy Aura
Whenever a creature enters the drowning devil's
heavy aura, it must succeed at a DC 18 Will save or reduce its speed as if carrying a load one step higher or wearing armor one category heavier (whichever is worse), and its armor check penalty increases by 2. A creature already carrying a heavy load or wearing
heavy armor that fails its save can't move as long as it remains in the affected area. A creature that saves against a drowning devil's
heavy aura is immune to that devil's aura for 24 hours. The save DC is Charisma-based.
