Circle of the desecrated

Like many druids you are part of a small community hidden in the wilderness. unlike many druids your community is a coven of occultists, and other worshipers of monsters. Your coven is not evil, instead believing that monsters, and other corrupted creatures are equally natural. Many types of outcasts are drawn to this small chapter, like werewolves, damphir, witches, warlocks, and monster lovers. The taboo nature of your relationship with death has forced your coven to work under the cover of darkness. You have come accustomed to the foggy, cold, dark nights used by the coven to practice their rituals. Your stewardship of monsters, fiends, aberrations, and the undead has given your coven unique abilities beyond the typical druid. Blood, decay, and death will come to your command, ripping vitality from the land and fueling creatures of darkness, restoring the balance of life and death. 

Deadshape

When wild shaping into a beast you instead transform into an undead creature of the same type. You retain all abilities, stats, and senses of the wild shape, with the additions:

While in wildshape, you cannot benefit from magical healing done by a player other than yourself.

At 2nd level when your wildshape hit points are dropped to 0, you role a d6, on a 1 the wild shape remains with hit points equal to 1+ your constitution modifier. If your wildshape took more damage that it had, then the damage carries over to your trueform, even if the wildshape remained due to this ability. At level 10 the wild shape will also remains on a 2.

Vampiric shape

Starting at 6th level, you can gain life energy by ripping the life force from an enemy, reinforcing the strength of your wild shape. On a turn that you kill an enemy of CR 1 or higher, you can instead drain the body of it's blood and life force. Anytime in the next 24 hours you can wild shape with spend 2 charges to increase your maximum wild shape CR to a third of your druid level rounded down.

Monstrous shape

Starting at 10th level, in addition to beast shape, you can use your action to magically assume the shape of a monstrosity that you have seen before. Your druid level determines the monstrosities you can transform into, as shown in the monstrosity Shapes table. If the creature you wildshape into has weapons, you do not have them while as that creature, likewise, if the creature has spell casting you do not gain those spells. Otherwise your abilities during monstrous shape are the same as during beastshape.
