The Trinity of Witches

Your patron is a trinity of three powerful witches. The trinity holds great power and they do not part with it freely. Tasks are liberally handed out by each of the three witches with little regard to the desires of the other two. Warlocks of the Trinity often times find themselves pulled in multiple directions as each member of their collective patron sets them to task seeking out arcane knowledge or objects of power. The three witches who make up the Trinity are The Child, The Mother and The Crone. The child is a master of Evocation and Transmutation magic magic, quick to anger and constantly chasing after temporary fascinations. The Mother is a master of Divination and Abjuration magic, somber and contemplative she looks to both the future and past for answers .The Crone is a master of Necromancy and Conjuration magic, she is the most powerful of the three but jealously guards her secrets.

Arcane Coven

Starting at 1st level, when you complete a long rest you may form a Coven with up to two willing spellcasters. When you establish this bond each coven member chooses one spell from their spell list to add to the coven list. Spells must be of a level which all members of the coven can cast. Coven members may cast spells off the shared coven list as if they were on their own list. 

Additionally, when casting a spell from the Coven list your Spell Save DC and Spell Attack Modifier increases by half your proficiency bonus, rounded down. 

 

Coven Spell Breaking

Starting at 6th level, your Patrons have shared with you the secrets of untangling magic. When you make an check to identify, counter or dispel magic, you may add a d6 to your roll. You may do so after seeing the initial roll but before any of the roll’s effects occur.

You may use this feature a number of times equal to your charisma modifier, you regain all uses after finishing a long rest.

Coven Bonus: When you attempt to dispel or counter magic targeting a coven member they may also roll a d6. You choose which one of these rolls you wish to add.

Fickle Dedication

Starting at 10th level, you may choose one of the Trinity to dedicate yourself to with when you finish a long rest. The Child: Evocation, Transmutation. The Mother: Abjuration, Divination. The Crone: Necromancy, Conjuration.

Upon doing so you gain a special spell slot that may only be used to cast spells of the school associated with your choice, you regain this slot on a short rest.

Additionally you gain the following benefit based on your choice:

The Child: Your spells deal additional damage equal to your half level, rounded down.

The Mother: You gain a bonus to saving throws and AC against spells equal to half your proficiency modifier rounded down.

The Crone: When you cast a spell you gain temporary HP equal to it's level, if the spell reduces an enemy to zero HP you also heal a number of hit points equal to the spells level. 

Coven Effect: You may expend your reaction to grant the associated benefit to a Coven member when they cast a spell, are target by a spell or are forced to roll a saving throw against a spell. The Coven member must be within 60 feet and you must be able to see them.

Unbreakable Coven

Starting at 14th level, you and your Coven share an unbreakable arcane bond.  When you cast a spell from your Coven List you may choose to allow other members of the coven to expend their reaction. Doing so allows them to immediately cast a spell as well provided it is on the Coven list, has a casting time of 1 action or 1 bonus action and the caster has the required level of spell slot. Each caster chooses the target of the spell individually and follows all other spell rules as normal.

If One or more Coven member casts a spell this way you have advantage on your spell attack roll and creatures have disadvantage on saving throws against your spell this turn.

Once you use this feature, you can’t use it again until you finish a long rest.
