From publisher blurb:
A Prestige Class for 5E from the Realm Scribe!
The bestial soul becomes a beast in the throws of the life and death struggle of survival. When they become a beast, they enter into a primal rage and fight as though death is the only option for them if they lose. As they become more in-tune with the power of nature, they learn to infuse their druidic magic into their fury, casting it instinctually.
This class is for high-level campaigns that allow for multi-classing in order for a character to meet the requirements for this Prestige Class. It is designed to fuse together the idea of a raging barbarian with a shapeshifting druid, and requires high wisdom and strength, levels in both the barbarian and druid classes, and to be at least 10th level before taking a level in this class. Prestige Classes are very powerful and meant for high threat campaigns.
Included in this product are the rules for Prestige Classes (as imagined by the Realm Scribe), the class, and 5 new Beasts between CR 3 and CR 7 (these beasts are also included in The Evolutionist Prestige Class).
