From publisher blurb:
The first Prestige Class for 5E from the Realm Scribe!
The Evolutionist uses arcane manipulation and inspiration from nature itself to alter the forms of the creatures of the world, but only through experimentation on a willing being; themselves. Whether it is becoming a flying monkey, an elephant with tentacles coming out of its back, or a crocodile that breathes lightning and can burrow through the earth, evolutionists specialize in becoming creatures with strange amalgams of traits.
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 shapeshifting druid with an experimental wizard, and requires high intelligence and wisdom, levels in both the druid and wizard 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.
