From the publisher:
Savage warriors of the Scarlet Axe tribe stalk the flinty uplands of the Black Hills. Guardians of the Yith's ancient, crumbling fortresses, the minotaurs wage unending bloody war against the centaurs claiming the surrounding desolate, windswept moorlands.
Minotaurs of the Black Hills presents:
Alternate class features for the sorcerer and ranger
Four new feats
Four new spells
Two new magic items used by powerful tribal members
Seven stat blocks (ranging in CR from 5 - 13)
Details of the Yith – an all but extinct ancient race of bat-like humanoids that yet dwell in the Black Hills.
Minotaurs of the Black Hills is designed to complement Centaurs of the Bleak Moor, but ownership of that supplement is not necessary to place this tribe in a GM’s personal campaign.
