Amulet of the World Tree

Forged from the roots of the World Tree, this amulet imbues its wearer with primal energy, granting them the ability to assume various roles in combat. By drawing on the raw power of nature, the barbarian can transform into different combat roles, gaining unique abilities and buffs for the duration of the encounter.

Properties

Once attuned, the barbarian can use the Amulet of the World Tree to assume a combat role by rolling a d8 at the start of combat. The role determined by the roll lasts until the end of the encounter or until the barbarian chooses to change roles by spending a bonus action to roll the d8 again. Each role comes with distinct buffs and a unique ability that enhances the barbarian’s power.

The amulet has 6 charges, regaining 1d4+2 expended charges at dawn. If all charges are expended, the amulet becomes dormant until it regains at least 1 charge.
