Circle of The Rot

You accepted the Rot God deal

Scarlet Aeonia

You channel the essence of Rot to summon a Scarlet Aeonia within 120 feet of you. This Aeonia creates a 40-foot radius of Scarlet Rot, which poisons the air and ground, forcing each creature beside you to make a constitution saving throw at the beginning of their turn or take [roll]{{(classlevel/2)@rounddown}}d6[/roll] necrotic damage and have their movement speed halved.

Child of The Rot

Also at 2nd level, your physical form begins to show signs of your devotion to The Rot. This can manifest as viny, beautiful scarlet blooms manifesting anywhere on your body, or your skin tinting a sickly shade of red, or even your hair falling out.

Additionally, while your Wild Shape feature transforms you, the essence of rot carries into this form, allowing you to deal an extra d8 of poison damage when you attack in your wild shape.

Command Over Rot

You gain the ability to use your Scarlet Aeonia's aura of Rot to either assist your friends or harm your foes. You may choose 3 Scarlet Incantations, and while your Scarlet Aeonia is active, you may use a charge of your wild shape to perform any of these incantations.

Chosen Corruption

The Children of the Rot do not turn on one another.

You're allies are given advantage on saving throws against your Scarlet Aeonia, and only take half damage on a failed save.

Decayed Healing

You use the death of some to grant life to others. 

If your Aeonia has caused a creature to take necrotic damage this round, you may use your bonus action to grant yourself or one of your allies temporary HP equal to half the damage that creature had taken.

Dehabilitating Disease

Your Rot seeps into your enemy's beings, causing them to struggle to even breathe.

Whenever a creature takes damage from your Scarlet Aeonia, you can use your reaction to cause that creature to have disadvantage on any attack rolls they make during their turn.

Diseased Strike

The Rot seeps in through open wounds.

Whenever you deal damage with a melee or ranged attack, you can use your bonus action to deal additional necrotic damage equal to your Scarlet Aeonia's Aura of Rot's damage.

The Rot is not just about disease, but also about revitalization.

Whenever an ally is in your Aura of Rot they gain +10 to their movement speed.

Exposing Disease

Rotted enemies struggle to avoid attacks.

Whenever a creature takes damage from your Aeonia's Aura of Rot, you may use your reaction to have the next attack against that creature to be at advantage.

Paralyzing Decay

The Rot slowly takes over the bodies of the diseased.

Whenever a creature takes damage from your Aeonia's Aura of Rot, you may use you're reaction to cause that creature to be for half of your proficiency bonus's amount of rounds.

During your turn, you can use your action to add your proficiency bonus to the armor class of any ally within your Aeonia's Aura of Rot for the next round.

Rotted Ground

The Rot reshapes any land.

During your turn, you can use your action to cause the ground within your Aeonia's Aura of Rot to become difficult terrain for your proficiency bonus ({{proficiency}}) amount of rounds.

Rotten Puppetry

Just because a creature's life ends doesn't mean it is no longer useful.

Whenever a creature falls to 0 HP in your Aeonia's Aura of Rot, you can use your reaction to command its corpse to make a melee attack against any creature within range.

Thriving Blooms

Starting at 10th level, your connection to the Rot is thriving, filling your being with life and granting you additional control over your scarlet Aeonia.

You gain immunity to Poison damage.

Rebirth Through Decay.

Whenever an ally falls in combat, you can use your action to immediately bring them up to half health, curing any status conditions they have. You can use this ability once per long rest.
