You are a blade of ruin clad in flesh, your strikes rot, your blood burns, and your will binds death to your cause. Whether wielded for vengeance, justice, or dominion, the dark answers your call.

Level 3: Umbral Essence

You gain resistance to necrotic damage.

Once per turn when you hit with a melee weapon attack, deal an extra 1d8 necrotic damage.

You can also inflict Scarlet Rot. The target must succeed on a Constitution saving throw (DC = 8 + your proficiency bonus + your Constitution modifier) or be poisoned until the end of your next turn. While poisoned, your weapon attacks deal an additional 1d8 necrotic damage to that creature.

You can use Scarlet Rot a number of times equal to your Constitution modifier (minimum once). Regain all uses on a long rest.

Level 7: Bone Shield

You can now use Second Wind on an ally within 30 feet instead of yourself.

When you do, the target also gains temporary hit points equal to half the healing (rounded down).

Level 10: Acidic Blood

You gain resistance to acid damage.

When a creature within 5 feet hits you with a melee attack, it takes acid damage equal to your Constitution modifier.

It must also succeed on a Constitution saving throw or be poisoned until the end of its next turn. On a success, it is immune to this effect for 1 hour.

Level 15: Horrid Strikes

Once per turn when you hit with a melee weapon attack, you can replace Umbral Essence’s damage with one of the following:

• Leeching Strike: Expend a Hit Die and heal for the total rolled + your Constitution modifier.
• Imposing Strike: Target makes a Charisma save or is frightened of you until the end of their next turn.
• Dread Cleave: Gain the Cleave mastery for this strike. If you already have it, apply Cleave again to another target within reach.

Level 18: Resilient Rot

While you have temporary hit points from Bone Shield, you have resistance to all damage except radiant.

Once per short or long rest, you can activate this resistance for 1 minute.
