The Codex Transigma

The Book of Transformation

The Chronicle of Nature And Change

While this book resides on the Prime Material Plane, transforming an unwilling creature into a new form requires a saving throw and concentration. Additionally, if the book does not reside on the Prime Material Plane, polymorph spells have a 25% chance of being permanent.

Friendly Neighborhood Mimic

Once per short rest, as a bonus action you may transform this book into either:

• The form of a simple or martial weapon. While in this form, you have a +3 bonus to attack and damage rolls made with the weapon.
• The form of any magic item with rarity uncommon or below.
• The form of any creature of CR ½ or lower.

This effect lasts for 10 minutes.

Call of the Wild

Once per day, you can cast Stampede in a 100’ radius
Stampede (battle magic): Range: 120’. Attack +12. Power +15. You summon allies from the Feywild to take the form of great powerful beasts. These beasts stampede through the battlefield, dealing damage to enemy units but leaving ally units untouched.

Identity Thief

This item contains 3 unreplenishable charges. While attuned to the codex, you may use an action to expend a charge and cast the spell shapechange.

Pseudodragons Are A Wizard’s Best Friend

If this book is ever not attuned to, it will transform into whatever object, creature, beast, or being it needs to in order to find someone new to attune to it.
