Moon Dregs

Your technique forms a poison unique to you and comes with your own shikigami to help manifest it.

Cursed Energy
Starting at 1st level, you can harness your negative feelings into a usable source of energy, called cursed energy. These feelings can be harnessed into attacks or abilities. The number of cursed energy you possess is based on your class, some classes use a modifier that being charisma or wisdom (Player’s choice)

Your cursed energy DC is 8 + user cursed energy ability modifier + proficiency bonus.

Lunar Jellyfish
Starting at 1st level, you can use your action to summon a Jellyfish shikigami, which lasts for 8 hours and uses your proficiency bonus. You can spend 1 additional cursed energy to change the shikigami’s size between tiny and large as an action. Moon Dregs only takes the dodge action unless you command Moon Dregs using your bonus action each turn. You can summon Moon Dregs for free once per long rest and again for 5 cursed energy. When Moon Dregs is destroyed, it cannot be summoned again for 1 minute.

Poisonous Cursed Energy
At 3rd level, your cursed energy has toxic properties which seep into Moon Dregs and empower it. Once per turn, when you or Moon Dregs hit a creature with a melee attack on your turn, you can spend 1 cursed energy to cause the attack to deal an extra 2d6 poison damage. This increases to 4d6 at 6th level, 6d8 at 11th level and 6d10 at 18th level. This damage is not amplified by a critical hit.

You can replace any of your attacks on your turn with an attack from Moon Dregs.

Noxious Poison
At 6th level, your cursed energy has become more corrosive and noxious, further seeping into Moon Dregs. When you use Poisonous Cursed Energy, a creature must make a Constitution saving throw or be poisoned for 1 minute. They can repeat the saving throw at the end of their turns, ending the effect on a success. While poisoned in this way, the target has a temporary level of exhaustion.

Moon Dregs can now make two attacks when it takes the attack action and can grant a creature three quarters cover while occupying a creature’s space, and full cover at 11th level.

Cleansing of Purity
At 11th level, you can add your Cursed Energy modifier to Moon Dregs’ AC as well as its Strength, Dexterity, and Constitution scores. Moon Dregs now makes three attacks when it takes the Attack action.

Domain Expansion: Liberation Rite of Water and Land
Finally at 18th level, you have created a domain embedded with your technique. The air is filled with toxins and appears as if you are underwater, counting as difficult terrain unless you have a swim speed. Creatures are still able to breathe normally.

At initiative 20, all creatures in your domain take 8d6 poison or acid damage. Moon Dregs attacks are imbued with your guaranteed hit and there are a number of tiny jellyfish shikigami swimming around equal to your cursed energy modifier that are also imbued with your guaranteed hit. You can command them as an action. They count as Moon Dregs, can only make 1 attack, and have 30 hitpoints.
