Inquisition Domain, (Grim Hollow Subclass)

The Inquisition domain reflects the order of the multiverse and the rejection of tainted magic, at least so far as certain celestial powers see it. Only the divine casters are pure and fit for use. Since arcane magic is strong enough to challenge the gods, divine beings of this domain, such as the Arch Seraph Empyreus, demand that magic-using mortals be kept in check. Most zealots root out all arcanists, while some strike fragile truces when complete removal isn’t feasible.

Bonus Proficiency

When you choose this domain at 1st level, you gain proficiency with martial weapons and heavy armor.

Witch Hunter's Strike

Channel Divinity: Spell Shield

Starting at 2nd level, you can use your Channel Divinity to bestow a temporary resilience to arcane harm.
As a bonus action, you present your holy symbol and choose a creature you can see (including yourself) within 30 feet. The chosen creature gains temporary hit points equal to 1d10 + your cleric level. While a creature has temporary hit points granted by your spell shield, it has resistance to damage from spells and advantage on saving throws against spells. The creature loses any remaining temporary hit points after 1 hour.

Rebuke Invoker

Starting at 6th level, as a reaction when a creature you can see within 60 feet casts a spell, you can force the creature to make a Constitution saving throw. On a failure, the creature takes force damage equal to 1d8 per level of spell slot expended casting the spell + your Wisdom modifier. Cantrips are considered first-level spells for this ability. On a successful save the creature takes half as much damage instead. You can use this feature a number of times equal to your Wisdom modifier (a minimum of once), regaining all uses upon completion of a long rest.
divine strike

Divine Strike

At 8th level, you gain the ability to infuse your weapon strikes with the power of celestial order. Once on each of your turns when you hit a creature with a weapon attack, you can cause the attack to deal an extra 1d8 force damage to the target.

When you reach 14th level, the extra damage increases to 2d8.

Supernal Safeguard

Starting at 17th level, when you use your Spell Shield feature, you can choose a number of creatures up to your Wisdom modifier (minimum 2) instead of choosing only one.
