Thanatos’s bloodline

You trace you lineage back to the god of death, Thanatos. And you use Constitution as your spell casting ability.

Chthonic Ancestor

At 1st level, you gain proficiency with the scythe and all martial and ranged weapons and necromancy spells use no spell slots at all.

Chthonic Resilience

As magic flows through your body, it causes physical traits of thanatos to emerge. At 1st level, your hit point maximum increases by 1 and increases by 1 again whenever you gain a level in this class.

Additionally, parts of your skin are covered by a thin sheen of pale skeletal bones. When you aren’t wearing armor, your AC equals 23 + your Dexterity modifier.

 You also gain critical advantage on initiative. [roll]3d20ad[/roll]

Chthonic Affinity

Starting at 6th level, When you cast a spell that deals damage of necrotic damage, you can add {{modifier:con}} to all damage rolls. At the same time, you gain immunity to necrotic damage

Etherial step

At 14th level, you gain the ability to cast misty step as a bonus action by spending 1 sorcery point to teleport and make nearby creatures afraid of you and nearby creatures must succeed a DC 26 (16 + CON) Constiution saving throw or become so frighted they throw up or faint.

Chthonic Presence

Beginning at 18th level, you can channel the dread presence of your ancestor Thanatos, causing those around you to become frightened. As an action, you can spend 2 sorcery points to draw on this power and exude an aura of fear to a distance of 300 feet. For 1 minute, each hostile creature that starts its turn in this aura must succeed on a DC 26 Constitution saving throw or be frightened until the aura ends. A creature that succeeds on this saving throw is immune to your aura for 24 hours.
