Collapse [R] Trigger The Kagaian skeleton is critically hit; Effect

Flurry of Claws [>] (flourish) As the monk's Flurry of Blows class feature. The Kagaian 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 As the monk feat. The Kagaian skeleton can Stride along vertical surfaces, such as walls, as long as it begins and ends its movement on a horizontal surface.

Water Step As the monk feat. The Kagaian skeleton can Stride across liquid surfaces. If it ends its movement on a liquid surface, it falls in as normal.

Whirlwind Kick [>>] The Kagaian skeleton makes a single Strike and compares the result to the AC of all creatures within its reach, dealing damage to each creature hit.
