Call of the Bone hunt (edited)

Many tribes and clans that live in monster infested area's face constant danger, and with the danger comes the need to adapt to their environments, gaining power from it. through the ancient rites and chants of the tribe, bards of the bone hunt use their methods of hymns and tribal performances to commune with the spirits of their slain monsters, and gain their strength. This is done in two methods, warriors and shaman, who preform the ancient rites for different results.

Warriors of bone sing their ancient chants to commune with the spirits of monster they've slain to bolster their power, gaining greater strength and power to defend the tribe. Shamans commune and command the spirits of monsters to bolster their spell work to aid the tribe.

Regardless of how, all must heed the call of the bone hunt, and hope they do not become the hunter's prey
