Urdefhan Lasher

CREATURE 7

Trained from a young age with the strange and powerful shauth lashes, urdefhan lashers would rather die than retreat from combat.

Translucent-skinned scourges of the Darklands, urdefhans are remorseless killers and foot soldiers of the world's end.

Greater Darkvision

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.

Necrotic Decay (divine, void)

When an urdefhan dies, its invisible flesh quickly rots away and sublimates into a foul-smelling gas that fills a 5-foot emanation around the body.

This gas deals 7d6 void damage to creatures in this area as their flesh curdles and rots as well (DC 24 basic Fortitude save).

Void Healing

A creature with void healing draws health from void energy rather than vitality energy. It is damaged by vitality damage and is not healed by vitality healing effects. It does not take void damage, and it is healed by void effects that heal undead.

Speed 25 feet

Melee Shauth Lash +18 (deadly d8, trip), Damage 2d8+7 slashing plus Grab plus Wicked Bite

Melee Jaws +17 (unarmed), Damage 2d6+7 piercing plus Wicked Bite

Divine Innate Spells DC 22, attack +14; 3rd Paralyze; 2nd Death Knell; 1st Feather Fall (At Will) (Self Only), Ray of Enfeeblement

Constrict

1d8+7 slashing damage, DC 25 basic Fortitude

The monster deals the listed amount of damage to any number of creatures Grabbed or Restrained by it. Each of those creatures can attempt a basic Fortitude save with the listed DC.

Shauth Seize

The lasher gains the Grab ability with a shauth lash and can use their Wicked Bite through magical shauth weapon Strikes.

Wicked Bite

Requirements The urdefhan damaged a creature with a jaws Strike on its last action

Effect The urdefhan maintains contact, turning the creature's flesh translucent around the site of the injury. The urdefhan chooses one of two options, each of which requires a fortitude save. If the jaws Strike was a critical hit, the creature suffers both effects, using the same save result for both.

Drain Blood DC 25 Fortitude The urdefhan drinks some of the creature's blood. On a failed save, the creature is Drained 1 and the urdefhan regains 10 healing HP (or, on a critical failure, it's Drained 2 and the urdefhan regains 20 healing HP).
Drain Vitality (necromancy) DC 25 Fortitude The urdefhan draws out some of the creature's vital essence. The creature becomes Enfeebled 1 for 1 hour on a failed save (or Enfeebled 2 for 1 hour on a critical failure).

Grab

Requirements The monster's last action was a successful Strike that lists Grab in its damage entry, or the monster has a creature Grabbed or Restrained

Effect If used after a Strike, the monster attempts to Grapple the creature using the body part it attacked with. This attempt neither applies nor counts toward the creature's multiple attack penalty.

The monster can instead use Grab and choose one creature it's grabbing or restraining with an appendage that has Grab to automatically extend that condition to the end of the monster's next turn.
