Willful Possession

As one of the most devoted followers of your faith, you are willing to make any sacrifice to your deity to accomplish their will. You become an avatar for your deity, and while transformed you gain the following benefits:

• You have advantage on all D20 Tests
• All creatures have disadvantage on D20 Tests imposed by you
• Casting spells of 6th level or lower does not require spell slots or material components
• You are immune to all damage inflicted by other creatures
• You can use your reaction to cast a spell, ignoring normal rules restricting the number of spells cast per turn

Maintaining this form strains you greatly. At the start of each of your turns, you can choose to dismiss this form. If you do not, your maximum hit points decreases by 15 points that cannot be reduced in any way. On a long rest, you recover 15 points of your hit point maximum. If this decrease reduces your hit point maximum to 0, you instantly die as you are erased—mind, body, and soul—from existence.
