Charge. If the rhinoceros moves at least 20 feet straight toward a target and then hits it with a melee attack on the same turn, the target takes an extra 9 (2d8) bludgeoning damage. If the target is a creature, it must succeed on a DC 15 Strength saving throw or be knocked prone.

As its name implies, this mammalian quadruped is visually striking for its colossal and impressive horn that, in adults, can grow to a length in excess of two feet. Aside from being a formidable natural weapon, rhinos with larger horns are seen as more suitable mates by others of their species.
Aside from its goring protrusion, these mammals are visually distinct from the more common rhinoceros by the coarse, blue fur that covers most of its otherwise leathery body. This, combined with fat reserves, aids its ability to dwell in the frigid landscapes and winter plateaus in which it primarily dwells.
These wild beasts make for prized game. Their great horns, thick exotic furs, and rich meats are all valuable commodities.
