Kroshik

A Kroshik devilsaur can be found circling the filth-pool of Ihgaluk Crag. Nearby Skumblade tribe saurok will stop what they're doing and turn to face him if he is close.

Occasionally, Kroshik will die and will be dragged to the altar at on the beach to be torn into by most members of the tribe. A day or so later, a Kroshik egg will be tended at Progenitus' spawn position on top of the crag. A few days after that, a baby Kroshik will be born and can be found wandering the crag.

According to Akolik, Thok the Bloodthirsty is Kroshik, defiled and twisted.

Bowing before all four forms of Kroshik is the requirement of the Pandaria quest achievement When in Ihgaluk, Do as the Skumblade Do.

Hemet Nesingwary somehow tamed Kroshik. It can be summoned Nesingwary's Lost Horn on Ashran.

In Kroshik's adult form, it has 3,447,200 health and the following abilities:

Kroshik does not drop any loot or award any reputation with The Black Prince. It can, however, be tamed.

Speculation

 * Kroshik may have been the only devilsaur native to the Isle of Thunder. As the other devilsaurs on the isle were brought there by the Zandalari.
 * Kroshik may also be some sort of demi-god, considering how he keeps coming back after the Skumblade saurok sacrifice and eat his corpse.
 * Kroshik is considered to be a gift from Kros, whom is worshipped as a god by the Skumblade saurok. Kroshik might thus be the offspring of Kros.
