HUNGER & SHIFTING FLESH.

The Shapeshifter Grimoire is a bestiary and campaign supplement for Dungeons & Dragons 5e, packed with the cursed, the feral, and the uncertain. It is a complete guide to were-creatures, transformation, and the quiet horror of not knowing whose skin you wear. Inside are fully realized NPCs, new magic items, and a library of DM tools built to turn any campaign into a story of infection, instinct, and identity.

Whether your party hunts beasts beneath a bleeding moon, hides among villages where faces change overnight, or becomes the very monsters they once feared, this Grimoire provides everything needed to make shapeshifting a living, breathing part of your world instead of a one-note curse.

What’s Inside The Shapeshifter Grimoire?

SHAPESHIFTING LORE

Study the six great lineages of transformation: Amphibian, Avian, Insect, Mammal, Reptile, and Sea. Each explores origin, instinct, and hierarchy: frogspawn ambushers from drowned ruins, feathered watchers who strike from above, hive-minded predators that think in numbers, and apex mammals who wear their hunger like faith. Learn their rivalries, their mutations, and what happens when they breed or feud.

SHAPESHIFTER INDEX

A complete roster of 72 shapeshifters, each with full humanoid tokens and stat blocks covering all forms.

4 Were-Amphibians like the Werefrog and Werenewt.
11 Were-Avians like the Werefalcon, Werevulture, and Wereeagle.
10 Were-Insects like the Werelocust, Werescorpion, and Werebeetle.
27 Were-Mammals like the Wereboar, Werejackal, and mighty Wererhino.
9 Were-Reptiles like the Werepython, Werekomodo, and deadly Werecrocodile.
11 Were-Sea Creatures from the Werecrab, Werebarracuda, and terror of the deep Wereshark.

Every shapeshifter features unique abilities, vivid lore, and dynamic artwork. These are not generic lycanthropes.
They are personalities, predators, and potential player mirrors.

MAGIC ITEMS

20 original items of mutation, mimicry, and metamorphosis. From cursed totems and shifting armors to relics that grant temporary control over the beast within, each reinforces the themes of change, temptation, and consequence.

WHY THE SHAPESHIFTER GRIMOIRE?

Because the horror of shapeshifting isn’t the claws... it’s the uncertain.
It’s not about the beast in the woods. It’s about the one in the mirror.

This Grimoire gives you tools to build campaigns where the line between ally and monster dissolves, where transformation is both power and punishment, and where every moonlit night asks the same question:

Who are you when the skin splits?

72 shapeshifters. 20 magic items. 15+ DM tool systems. One infection that never stops spreading.
The moon is up. The hunt begins.
