This magical pendant has upon it an etching of the legendary Yggdrasil world tree.

This item allows the wearer to absorb a spell's power that has been cast targeting the wearer and restore the wearer. When the wearer is targeted by a spell, they may use their reaction to absorb the spell, negating its effects, and store a number of charges equal to the level of the spell absorbed, to a maximum of 2 charges. Once absorbed, the charges may then be expended to restore to the user a spell slot of a level equal to the number of charges expended. Additionally, the wearer's skin is hardened, reducing damage and making them harder to hit. While attuned, the wearer's base Armor Class is 14, and if the wearer is equipped with armor their AC can never go below 14.

This magical item gains new properties as its attuned user levels up, gaining new powers as the wearer reaches levels 6, 10, and 15.

- At level 6, the item gains 2 additional slots for charges absorbed from a spell, increasing the maximum to 4. The AC base level is increased to 15. In addition, at the end of a long rest the wearer gains a number of temporary hit points equal to half their Druid level + their CON modifier.

-At level 10, the item gains another 2 charge slots, to a total of 6. The wearer's base AC is increased to 16. At the end of a long rest, the wearer gains the above number of temporary hit points. In addition, the wearer's CR limit for Wild Shape is increased by 1.

-At level 15, the item gains another 3 charges, to a maximum of 9. The wearer's base AC is increased to 17. At the end of a long rest, the wearer gains temporary hit points equal to their Druid level + their CON modifier. The wearer's CR limit for Wild Shape is increased by 2.
