Circle of Death

The vast majority of druids believe in the circle of life and how it is not to be interrupted but protected. Druids of the circle of death believe in manipulating the circle of life to their making. These druids believe that all life ends in death and so the circle remains unbroken by their dark magic. Due to these conflicting interests, druids of the circle of death are often outcast or even hunted by other circles.

Death Begins

At 2nd level you can drain energy from creatures. You gain a pool of d6s equal to your druid level. Whenever you succeed on a melee or spell attack against a single creature, you can spend these d6s to deal necrotic damage to the target. You can also heal 1 hit point per dice spent. You regain all expended dice on a long or short rest.

Circle Spells

Your mystical connection to death infuses you with the ability to cast certain spells. At 3rd, 5th, 7th and 9th level you gain access to circle spells connected to your understanding of life and death.

Once you gain access to a circle spell, you always have it prepared, and it doesn't count against the number of spells you can prepare each day. If you gain access to a spell that doesn't appear on the druid spell list, it is nonetheless a druid spell for you.

Druid Level Circle Spells 3rd blindness/deafness, gentle repose 5th bestow curse, vampiric touch 7th evard's black tentacles, phantasmal killer 9th negative energy flood, raise dead

Reject Death

Starting at 6th level, you gain the abilty to cling to life. When you are reduced to to 0 hit points but not killed outright, you instead drop to 1 hit point. You can't use this ability again until you finish a long rest.

Additionally, instead of stabilising after you succeed on a death saving throw, you can spend a number of hit dice equal to your Wisdom modifier and heal the amount rolled.

Shape of Death

At 10th level, you can use your Wild Shape ability to become a Will-o'-Wisp. Alternatively, you can expend two uses of Wild Shape at the same time to transform into a Wraith.

Unnatural Warrior

At 14th level, whenever you touch anything made of metal, you take 1d10 radiant damage and make your next attack roll or ability check with disadvantage. Also, you no longer need to eat, sleep or breathe, you don't have a heartbeat and your creature type becomes undead.

Life Ends

Also at 14th level, you can touch a creature in an attempt to kill it instantly. If the target has 10d10 or fewer hitpoints, it dies without making any death saving throws. Otherwise, this ability is wasted. You can't use this ability while wildshaped and regain this ability after a long rest.
