Hecate

Worshippers of Hecate - often misunderstood, are complex, passionate, and dangerous forces of nature. Often conflated with worshippers of demons and other hellish creatures, the servants of Hecate instead worship an ancient deity of magic, moonlight, doorways, and creatures of darkness. For every bit that Hecate is the night, she is also the moonlight that illuminates the dark. For every dark, hellish guardian blocking the way on her behalf, she creates a door to escape.

The Night's Puissance

Starting at 1st level, when you cast a spell that deals radiant or necrotic damage, you add your charisma modifier (minimum 0) to the damage dealt by that spell.

Death's Door

Starting at 6th level, you have learned how to briefly cross through the realm of the dead to escape a deadly fate. Whenever an enemy hits you with an attack, you may use your reaction to teleport 30 feet to an unoccupied space you can see.

When you do, the attack deals no damage to you, but you instead take 1d8 psychic damage. You cannot use this ability again until you finish a short or long rest.

Nyctophile's Elusivity

Also at 6th level, you gain proficiency in stealth if you are not already proficient. Also, you may use your Charisma bonus instead of your Dexterity bonus when making a Stealth skill check in dim light or darkness.

Maid, Mother, Crone

Starting at 10th level, you have learned to take on one of the more eerie and terrifying aspects of Hecate.

When you cast the Mirror Image spell, Illusory copies cannot be perceived as illusions, except with truesight. Also, you can use a bonus action to create a new copy (maximum 3), as long as the spell is still active.

You can cast Mirror Image once without using a spell slot. When you do, you can't do so again until you finish a long rest.

The Ferryman

Starting at 14th level, you gain the power to open a door to the underworld to summon forth a powerful undead ally. As an action, you may cast the Summon Undead as if cast at 7th level, without using a spell slot.

When you cast the spell in this way, you do not need to use concentration to maintain the spell and the creature gains, "This creature deals an amount of necrotic damage equal to your proficiency bonus each time it hits an enemy with an attack."

You cannot use this ability again until you finish a long rest.
