Baykok
About
A skeleton with skin stretched over it, thin enough to see the shape of everything underneath, and eyes burning back in the sockets. It hunts warriors and only warriors, and it takes the liver and leaves everything else. You hear the bow. That is all the warning there is - a bowstring, close, in the dark, and then somebody in the line is on the ground with no wound on them at all.

Special Attack
Invisible Arrow: 120 ft, no line of sight required if it can hear its target. Save Dex Quick, fail save roll 2d8+3 - and DR does not apply, because nothing physical arrives. The wound cannot be found. Cooldown 1 round. Club: bludgeoning, melee 5 ft, +4 to hit, 2d8+3, used to finish those already down.
Special Defense
Hunts Warriors: it will not target a creature that has not taken up arms in its life, and it can tell. Non-combatants are ignored entirely, walked past, and left alive to describe it. Paralysing Cry: the first time it shrieks in an encounter, every creature that has killed must save Wis Mind or lose its next turn.
