Feywildcraft

Gesturing to the spirits of nature and the Feywild, you create one of the following effects within range:

• You make a melee spell attack on an undead creature, stealing some of it's spirit and cleansing it from taint, and storing the power stolen from the undead creature in a Wildseed. The attack does 1d8 radiant damage + your spell attack modifier. A successful attack adds 1 charge to your Wildseed.
• Once a Wildseed has 10 charges of spirit stolen from an undead creature is is considered fertilized, you may instantly plant a Wildseed with this spell and have it start to grow, creating a sapling of a plant known to the user that exists in the Feywild. By planting the Wildseed, it creates a new domain of the Feywild or expands an existing domain of the Feywild in a radius of 30 feet centered on the Wildseed.
• You may release the charges within a Wildseed. This heals any one Fey or Fey ancestry-like creature or plant of your choosing (including Elves) within a 30 feet for 1d8 per charge. 

At higher levels: When you cast this spell using a spell slot of 2nd level or higher, increase the damage done to an undead creature by 1d8, and increase the charges stored in the Wildseed by 1 for each per spell slot above 1. Using a higher level spell slot to release charges from a Wildseed does not change the amount of healing the spell does.
