Arcane Tradition: Demonology

### Arcane Tradition: Demonology

Demonologists are a group of wizards who focus their studies on demons, vile creatures who dwell in the Abyss. They possess formidable knowledge around everything about demons and the Abyss.

Demonologists are the only known group capable of some level of control over the demons. They also bend the flesh-twisting energies of the Abyss to enhance their demonic minion.

#### Dreadful Grimoire

*2nd-level Demonology feature*

___
The forbidden lore and corrupted arcane sigils contained within your spellbook have forged a connection between it and the Abyss, turning the book into an ancient grimoire. The grimoire acts as a normal spellbook with the following changes:

* You can use your grimoire as a spellcasting focus for your wizard spells.
* You can replace your grimoire by using unholy incantations to write Abyssal sigils in any book or a magic spellbook to which you're attuned for a duration of 1 hour. You can do this as a part of a short rest. At the end of the rest, the signs you wrote corrupt the book, removing any old non-magical writings and transferring your spells from your old grimoire into the new one, even if the original is destroyed. If the previous book still exists, it turns into a foul mess and is destroyed along with spells in it.

#### Demon Minion

*2nd-level Demonology feature*

___
Your research of abyssal powers contained within the grimoire has borne you an ability to summon a demonic minion. You perform a 10-minute ritual (it can be done during a short or long rest) to summon a demon of your choice: a lurker, a striker, or a ravager (see the stat block below). The demon remains by your side until its hit points are reduced to 0 or you dismiss it as an action.

The demon minion is unfriendly toward you and your party. It acts freely by its whims. It obeys your commands if they are aligned with its ethos; otherwise, it strives to twist your commands to achieve its own objectives.

In combat, the demon shares your initiative count, but it takes its turn immediately after yours. You must use your action to order the minion to use one of its actions. Otherwise, your demon can only move and take the Dash, Disengage, Dodge, Help, and Hide actions and reactions.
Once you summon your demon minion, you must finish a long rest to do so again.

#### Abyssal Enhancement

*6th-level Demonology feature*
___
You learn more fiendish secrets from the grimoire, expanding your demonology knowledge. Choose one of the following options. You can choose an additional improvement on level 10th and 14th.

***Abyssal Resilience.*** The demon’s hit points maximum is increased by 20. It also gains resistance against bludgeoning, piercing, and slashing damage from nonmagical attacks.

***Aura of Fear.*** Any creature of the demon’s choice that starts its turn within 15 feet of it must succeed on a Wisdom saving throw against your spell save DC or be frightened of it until the start of its next turn. On a successful saving throw, the creature is immune to this effect for 24 hours.

` ` ***Blazing Haste.*** When you are hit with an attack or a spell and the demon is within 120 feet of you and can see or hear you, the demon can take a reaction to instantly move up to 50 feet in any direction. When it does so, the demon can pass through other creatures that are then forced to make a Dexterity saving throw against your spell save DC. On a failure, the creature takes fire damage equal to half your wizard level and becomes blinded until the start of the demon’s next turn. A creature that succeeds on the save takes half damage and is not blinded. The demon can use its reaction in this way a number of times equal to your proficiency bonus before you finish a long rest.

***Consume Spell.*** When the demon hits a creature concentrating on a spell, the target makes Concentration check with disadvantage. On a failure, the demon gains temporary hit points equal to your proficiency bonus. In addition, its next attack deals an extra die of damage.

***Deteriorate Magic.*** The demon can use the Help action to grant a creature it can see within 15 feet of itself advantage on the first saving throw it makes against a spell or magical effect before the start of the demon’s next turn.

***Demonic Flight.*** The demon gains 30-foot flying speed.

***Fiendish Strikes.*** The demon can make two melee attacks when it takes the Attack action. In addition, the attacks count as magical for the purpose of overcoming damage resistance.

***Fortitude of the Abyss.*** The demon gains two saving throw proficiencies of your choice. It uses your proficiency bonus.

***Funnel Madness.*** Each creature of the demon’s choice that starts its turn within 5 feet of it must make a Wisdom saving throw. On a failure, it takes psychic damage equal to your proficiency modifier. On a successful saving throw, the creature is immune to this effect for 24 hours.

***Infinite Improvement.*** You can increase two of your demon’s ability modifiers by 1, up to the maximum of 5. In addition, the demon gains proficiency in two skills corresponding with each chosen ability. It uses your proficiency bonus.

***Sustenance.*** Whenever the demon or you regain hit points, the other regains half of the amount if you are within 30 feet of each other.

***Wicked Corruption.*** When you and the demon are within 30 feet of each other, you can use a bonus action to expend a spell slot. For 1 minute afterward, each creature hit by the demon’s melee attacks is corrupted. Until the start of the demon’s next turn, the corrupted creature must roll a d4 after each attack roll, ability check, and saving throw and subtract the result from the total.

#### Master’s Will

*10th-level Demonology feature*
___
You build a stronger connection with your demon minion. It becomes friendly towards you and your party. You don’t need to use your action to order your demon minion to use its action to perform an action other than the Dash, Disengage, Dodge, Help, and Hide actions.

In addition, when you use your action to cast a spell from the grimoire, your demon minion can deliver the spell as if it had cast the spell. The demon must be within 60 feet of you, and it must use its reaction to deliver the spell when you cast it. If the spell requires an attack roll, you use your attack modifier for the roll.

#### Fiendish Tyrant
*14th-level Demonology feature*
___
You learn the planar binding spell if you don’t already know it. You can cast it without expending a spell slot and as an action if you target a fiend. The fiend’s true name appears in your grimoire for the duration. You must finish a long rest to use this feature again.
