the eldritch horror

an unspeakable horror sutch as a void or Satan has given you power or you gained it somehow, these powers are heavy on your heart but provide unearthly powers.

brimstone

starting at 1st level, you can channel your souls magic into a powerful blast. as an action on each of your turns, you can harness the power of your deity. if you spend 4 actions total in a single combat doing this, on your fourth you release a beam of hatred and fear from you. its a 200ft range beam that spurts form you and deals 7d6 + 20 force, fire or necrotic damage to all in its range, you can also choose if you want the creatures who got hit to make a wisdom save (spell save dc) or be frightened by you for 1 minute. once this ability is used, it cannot be used in the same combat. hostile creatures who see you charging the beam get a sense of impending dread and understand its power.

shrouded

at 6th level, as a bonus action you can make a thick mist surround you for 30 seconds, to a bystander you are completely covered by this 10ft by 10ft mist that moves with you, you can choose one of the abilities for this mist.

TERROR: any creature that looks at you must make a wisdom save at disadvantage or be frightened for the mists duration. if the creature chooses not to look at you, it acts like it has the blind condition to just you

CHANNEL:  the mist goes a color of your choice as the mist helps you channel your faith to your deity. all personation, religion and performance checks done to talk, or serve your deity are done so with advantage.

SURROUND: the mist forms crystals that swirl around as the mist does. anyone who gets within 10 feet of you, must succeed a Dex save or take 5d4 slashing damage and take 1d4 damage on subsequent turns as the crystals get lodged in their skin and cause mass bleeding until the mist disapears.

PROTECT: the mist turns night black and attempts to cover every part of you. while the mist is in effect, you count as behind half cover, you are covered in magic darkness but can still see, and when charging brimstone, no one is alerted to it as long as your behind this mist

you can use this effect as many times as your proficiency bonus per long rest.

fire and brimstone

at 10th level, your bond between your deity and you thicken, it now takes 4 actions in a combat to charge brimstone. all your eldritch evocations now apply to your brimstone now as well.

possession

at 14th level, your eldritch being can open an ever so brief portal to your mind and enter your body if you allow it, you can choose how much your deity possesses you and gain the following benefits for 5 turns:

FULL BODY POSSESSION: in a moment of desperation, you give your whole body up to your being, they will gladly accept and take full control for the duration. while kicked out of your body, you must make death saving throws with advantage, if 3 saves are achieved, you reinhabit your body at the end of your duration, otherwise you are killed. while your deity in your body, you gain the following abilities: + 5 and advantage to all saves and checks. shrouded ability is immediately activated. can do brimstone every turn as long as eldritch blast action was expended. you gain + 3 to ac and resistance to all piecing slashing and bludgeoning damage. all your attack rolls and damage rolls increase by + 5 . if your deity has a flying speed, you gain it. once this effect has ended, if you made your 3 saves you return to your body with 5 points of exhaustion. if you died during possessions,  your deity retreats to its last plain and your body explodes in a gory mess. every creature withing 30 ft must make a dex save or take 20 necrotic damage as festering blood chunks melt their skin.
