The Deranged

A Powerful and Deranged being has chosen you to be their champion, and that typically entails carrying out deeds to incite madness and to revel in dementia and mania, all while using it to further your own powers.

The Deranged Expanded Spell List

The Deranged lets you choose from an expanded spell list of spells when you learn a warlock spell. The following spells are added to the warlock spell list for you.

 1st Level: Hideous Laughter, Chaos Bolt

2nd Level: Tasha’s Mind Whip, Phantasmal Force

3rd Level: Speak with Dead, Bestow Curse

4th Level: Confusion, Phantasmal Killer

5th Level: Modify Memory, Mislead

Sicken the Mind

At 1st level, your patron gives you the power to spread their maddened influence. Whenever you expend a warlock pact slot or cast a leveled enchantment spell, you may expend your bonus action to have a creature you can see within 30 ft make a Charisma saving throw equal to your spell save DC, if they fail they roll on the short-term madness table from the DMG except the effect lasts until the start of your next turn instead of 1d10 minutes. You can use ability a number of times equal to your proficiency bonus, and resets on a short rest.

Indulge in Insanity

At 6th level, you become a manipulator of the psyche of others, learning the secret magics that let you send others into mania or dementia. When you use the Sicken the Mind feature, you may choose Mania or Dementia to use an additional effect. You can use this effect equal to your proficiency bonus per long rest

Mania: You can target an additional creature with Sicken the Mind equal to your Charisma modifier (minimum of 1).

Dementia:The creature you target with Sicken the Mind, their save is done at disadvantage, and if they fail by 5 or more, they roll on the long term madness instead. This effect lasts for 1 minute.

Lingering Madness

At 10th level, your exposure to the insane has made you callous to its effects, but not without coming out a little twisted yourself. You gain your choice of an indefinite madness trait on the indefinite madness table from the DMG. You also gain resistance to psychic damage, and any attempt to invade your mind are now easier to assess. If you have to make a saving throw to resist an invasion of your mind, your roll is done at advantage, but if the invader must make a saving throw or attack roll to invade your mind unwillingly, those rolls are done at disadvantage.

The Deranged Mystic Arcanum

Additionally, the following spells are added to your Mystic Arcanum as options:

6th Level: Otto’s Irresistible Dance

7th Level: Mirage Arcane

8th Level: Antipathy/Sympathy

Conduit of Chaos

At 14th level, you no longer need an arcane focus to cast spells with material components that don’t require the material to be consumed. Whenever you use sicken the mind, you may instead have the target/targets and you roll on the Wild Magic Table and undergo the effects. You may use this ability a number of times equal to your proficiency bonus per long rest.
