Levaloch

A creature with greater darkvision can see perfectly well in areas of darkness and dim light, though such vision is in black and white only. A creature with greater darkvision can see through even forms of magical darkness.

A monster with telepathy can communicate mentally with any creatures within the listed radius, as long as they share a language. This doesn't give any special access to their thoughts, and communicates no more information than normal speech would.

A levaloch ignores the effects of non-magical difficult terrain. They take no damage from caltrops or from damaging terrain that deals physical, acid, or cold damage. A levaloch can move through liquids up to 5 feet deep at their full Speed.

All devils of equal or lower level adjacent to a levaloch gain a +1 circumstance bonus to their AC as the levaloch shields them from harm. Effect: Phalanx Fighter

A levaloch gains a +2 circumstance bonus to their Fortitude DC against being Shoved and to other saving throws to resist being moved against their will.

When a levaloch hits a creature with their barbed net, the net wraps around the target, which becomes Clumsy 1 and takes a -10-foot circumstance penalty to its Speeds. If the Strike was a critical success, the target is also Immobilized. When a creature Escapes, or if the Strike misses, the net crumbles into rust. Each time a creature attempts to Escape, it takes 1d6 slashing damage from the net's barbs, regardless of whether the attempt succeeds. Effect: Barbed Net

A levaloch reforges part of their barbed iron substance into a new +1 Striking trident or barbed net. Their previous trident crumbles to rust. When the levaloch is destroyed, any tridents or barbed nets they created crumble to rust.

When a levaloch hits a creature that has the Clumsy, Enfeebled, Immobilized, or Restrained conditions with a melee trident Strike, the Strike deals an additional 2d6 damage.
