#### Codex Mutabilis Wondrous item, artifact (requires attunement) --- The codex mutabilis was first drafted by Zahra al-Atallah, the High Transmutor, Hazarite lord alchemist in the court of Khwaja ud-Dīn during the second century of the Age of Wonder. It extrapolates on her theory that law and chaos are both largely irrelevant to the true nature of the timescape, which only has one essential quality: change. Zahra al-Atallah and her students argued that there is no cosmic balance that should be preserved, but neither are events wholly random and unpredictable. This thesis became highly controversial, eventually leading to her exile and the loss of the book. *"All things are made of the same essential matter, therefore no real obstacles stand in the way of one thing becoming another, or of one person becoming another. In fact, we all change constantly, without even noticing."* The codex mutabilis's written language changes every 10 years. It is currently written in Infernal. A creature that attunes to the codex mutabilis and understands its secrets gains the following abilities. ***High Transmutor.*** While you carry the codex mutabilis, transmutation spells you cast are treated as if you used a spell slot one level higher to cast them (up to a maximum of 9th level). Additionally, you can touch a Tiny nonmagical object and change the properties of its materials. It takes 1 minute to change the properties of a cubic inch of liquid or solid material, such as turning a copper coin into gold, and 1 hour to change a cubic foot of liquid or solid material, such as turning a portion of a stone wall to dust, or a small cask of water into wine. ***Untethered Form.*** While you carry the codex mutabilis, you can cast the *shapechange* spell at will. In addition, you can cast the *plane shift* spell to send yourself or other creatures to Primordus, the Sea of Eternal Change. Charisma is your spellcasting modifier for these spells. Once you cast the *plane shift* spell using the codex, you can't do so again until you finish a long rest. ***One Space is the Same as Any Other.*** When you are targeted with an attack while you carry the codex mutabilis, you can use your reaction to teleport up to 300 feet to an unoccupied space you can see, causing the attack to miss. ***Chromatic Organum.*** While you carry the codex mutabilis, you can choose one damage type as a bonus action. You gain immunity to this damage type and all spells you cast that deal damage use this damage type instead of their normal type until the start of your next turn. ***The Wheel Turns.*** If you die while attuned to the codex mutabilis, you are automatically subject to the *reincarnate* spell, and your new body awakens somewhere else on your current plane of existence. The codex mutabilis is no longer attuned to you and vanishes, reappearing elsewhere in the timescape. ***Catastrophe Theory.*** As an action, choose one creature you can see within 120 feet of you and sacrifice up to half your maximum Hit Dice. The next time that creature takes damage, roll the sacrificed dice and add the result to the damage taken. ---
