Druid: Circle of Blood (Homebrew: Grim Hollow)

The Circle of Blood is a keeper of old ways. They remember how ancient druids performed sacrificial rituals under a blood-red moon to appease the uncaring forces of nature. The Circle of Blood druid trades blood for life in a delicate balance to bolster their allies and destroy their enemies.

Circle Spells

At 3rd, 5th, 7th, and 9th level you gain access to the spells listed for that level in the Circle of Blood Spells table.
Once you gain access to one of these spells, 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, the spell is nonetheless a druid spell for you.

Blood Boon

When you choose this circle at 2nd level, when a creature you can see within 60 feet of you dies, you can use your reaction to claim the last vestiges of its vitality. You regain one previously spent Hit Dice. When you do, you can grant a creature you can see within 60 feet of you a number of temporary hit points equal to your druid level. You can use this feature a number of times equal to your Wisdom modifier, regaining all expended uses at the end of a long rest.

Rite of the Blood Moon

At 6th level, you learn a rite that invokes the power within a creature’s blood. As an action, you can expend one use of your Wild Shape class feature to drive yourself or a willing creature within 5 feet of you into a blood frenzy that lasts for 1 minute. The affected creature gains the following benefits:

• It gains resistance to bludgeoning, piercing, and slashing damage against weapons which are not magical.
• It gains darkvision to a range of 60 feet and advantage on Wisdom (Perception) checks.
• It can roll a d8 in place of the normal damage of its unarmed strike. When it takes the Attack action on its turn, it can make one attack with its unarmed strike as a bonus action.
• Its speed increases by 10 feet.
• It can’t speak or cast spells.

Only one creature at a time can be affected by your Blood Rite. If you use the Rite of the Blood Moon on another creature, the effects of the Rite end for any other creature.

Blood Lust

Starting at 14th level, when a creature you can see within 60 feet of you dies, you can use your reaction to fully exsanguinate its corpse, conjuring a water elemental composed of its blood and bound to your service.
Roll initiative for the elemental, which has its own turns. It obeys your verbal commands. The elemental remains in your service for 1 hour or until it is reduced to 0 hit points, at which point it collapses into a pool of blood.
Once you conjure an elemental with this feature, you can’t use the feature again until you finish a long rest.
