The Corrupt

You have made a pact with a forgotten, ancient being. They long for their name to be remembered, for the world to revere or fear them. The alignment and goals of this being should be discussed between you and the GM.

Expanded Spell List

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

Corrupt Expanded Spells

Spell Level	Spells
1st	bane, inflict wounds
2nd	blindness/deafness, wither and bloom
3rd	bestow curse, vampiric touch
4th	black tentacles, phantasmal killer
5th	contagion, dominate person

Tainted Weave

The source of your power is inherently corrupted, when you draw on the weave of magic to cast a spell some of the corruption bleeds through tainting your body. Whenever you cast a levelled spell, you gain 1 point of Corruption per level of the spell. Each point of corruption reduces maximum hitpoints by 3 but you gain an additional 1d4 to any spell damage you inflict.

If casting a spell would reduce you to less than 1 maximum hitpoint, you instead are dropped to 1. You only gain Corruption points for every 3 hitpoints removed.

You lose a number of Corruption points equal to your spell slots on a short rest and all Corruption points on a long rest.

Eternal Thrall

Starting at 6th level, you can call on your eternal thrall to serve you. You can summon the thrall at a point anywhere you can see within 30ft by expending all Corruption points. During combat, you use your bonus action to command the thrall to either attack or move. If you do not give it a command, it will take the dodge action. The thrall will take its turn immediately after yours.

The thralls hitpoints, attack and damage depend on the number of Corruption points spent. Any damage you take while the thrall is alive is halved and the thrall takes the same amount of damage as you. If the thrall is reduced to 0 hitpoints, the body turns to ash.

Empowered Corruption

The name of your Patron has spread wide, allowing them to access some of their former power. They grant you the following benefits:

Tainted Weave: The additional damage you deal goes up to 1d6 per point of corruption.

Eternal Thrall: When the thrall is below half its total hitpoints, you can cause it to detonate, dealing 6d6 necrotic damage to all creatures within 10ft. You regain hitpoints equal to the damage dealt.

Unshackled Corruption

Your Patron has unlocked more of their power, granting you additional benefits:

Tainted Weave: The additional damage dealt goes up to 1d8 per point.

Eternal Thrall: The damage goes up to 8d8 necrotic and the detonation is larger based on the amount of missing health below half.
