Collapse

Trigger The Iroran skeleton is critically hit

Effect The Iroran skeleton collapses into a pile of bones and the attack deals damage for a hit, rather than a critical hit.

The skeleton can reform in a standing position as an action, but until it does, it is Immobilized and Off-Guard.

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 45 feet

Melee Claw +24 (agile, finesse, unarmed), Damage 4d6+12 slashing

Flurry of Claws (flourish)

The Iroran skeleton makes two claw Strikes. If both hit the same creature, the damage is combined for the purpose of resistances and weaknesses.

The multiple attack penalty applies to the Strikes as normal.

Wall Run

The Iroran skeleton can Stride along vertical surfaces, such as walls, as long as it begins and ends its movement on a horizontal surface.

Water Step

The Iroran skeleton can Stride across liquid surfaces. If it ends its movement on a liquid surface, it falls in as normal.

Whirlwind Kick

The Iroran skeleton makes a single Strike and compares the result to the AC of all creatures within its reach, dealing damage to each creature hit.
