5e-Demonology Domain-Thoughts?

Demonology Domain

Theology and Demonology have always been two sides of the same coin. For as long as scholars have studied the divine, others have studied the profane. Clerics that study demons are forced to walk a fine line between salvation and damnation. Will you use this knowledge to fight back corruption, or will you take the easy way to power?

Demonology Domain Spells
Cleric Level Spells
1st Chaos Bolt, Protection from Good and Evil
3rd Shatter, Flock of Familiars
5th Magic Circle, Summon Lesser Demons
7th Banishment, Summon Greater Demon
9th Planar Binding, Contact Other Plane

-Demonic Knowledge: When you choose this Domain at 1st level, you have a rudimentary knowledge of demonic lore. You are able to speak, read, and write Abyssal fluently. Additionally, you gain proficiency with 2 of the following skills: Arcana, Religion, Investigation, History, or Insight.

-Bound Underling: At 1st level, you gain the Find Familiar ritual spell. This spell always summons a Quasit. This counts as a Cleric spell for you, and does not count against the number of spells that you can prepare each day.
If you wish to conceal your familiar you may, as a Bonus Action, absorb your familiar into your body. If your familiar is reduced to 0 HP you may also absorb it as a Reaction. Expelling the demon back into physical form requires no action. If you die while joined you will both die.
While absorbed you can hear your familiar’s voice in your mind, and if you will it, allow it to speak through you.

-Channel Divinity: Chastise Fiends: Starting at 2nd level, you can use your Channel Divinity to turn or command the damned.
As an Action, you present your unholy symbol, and one Fiend of your choice that is within 30 feet of you must make a Wisdom saving throw, provided that the creature can see or hear you. If the creature fails its saving throw, it is turned for 1 minute or until it takes any damage.
A turned Fiend must spend its turns trying to move as far away from you as it can, and it can't willingly end its move in a space within 30 feet of you. It also can't take reactions. For its action, it can only use the Dash action or try to escape from an effect that prevents it from moving. If there's nowhere to move, the creature can use the Dodge action.
At 5th level, whenever a Fiend fails it’s saving throw against your Chastise Fiends feature, the Fiend is Charmed for 1 minute. After the Charm expires the Fiend knows that it was charmed, and who charmed them.

-Damnable Will: At 6th level, your connection to your demonic familiar allows you to call upon its strength of will to aid your own. While absorbed, the presence of a second mind grants you advantage on saves against charm and fear effects. While your forms and minds are bonded, you also have advantage on saves to maintain concentration on spells.

-Unholy Strikes: When you reach 8th level, you are blessed with unholy might in battle. When a creature takes damage from one of your cantrips or weapon attacks, you can also deal 1D8 Necrotic damage to that creature. Once you deal this damage, you cannot use this feature again until the start of your next turn.

-Tongue of the Black Speech: At 17th level, you gain the ability to speak a few words of the foulest demon lord’s curses. You gain Disintegrate, Power Word: Pain, Power Word: Stun, and Power Word: Kill as bonus spells. You add these spells to your list of Domain Spells, and like other Domain Spells, they are always prepared and count as Cleric spells for you. These spells require on the verbal components for you.

Spell List
Chaos Bolt feels weird. Otherwise no big comments.

Demonic Knowledge
Demonic is not a language in 5E. Abyssal is what you're looking for, methinks.
What happens if you already have four or five of the skills listed?

Bound Underling
Find Familiar lets you stick them in a pocket dimension already. Is the hide in your body in addition to or instead of that?

Channel Divinity
At level two, feels weak. Compare to Turn Undead hitting ALL undead within 30'.
But at level five, hoo boy. That feels REALLY strong.

Damnable Will
Neat.

Unholy Strikes
Okay.

Tongue Of The Black Speech
Seems reasonable, if a little dull.

Updated original post:
-Replaced some domain spells
-Fixed the language to Abyssal-Honestly I’m not sure what kind of brain fart happened there I know better than that lol
-Modified Channel Divinity (the possibility of dominating a balor at lvl 5 mighta been a bit much.


As for the absorbing quasit, just thematic to a demonologist. A little pseudo-possession. Carrying him around in your body just keeps you from having to cast and recast the ritual.
