The Contractor

Your patron is an entity tasked with upholding promises throughout the cosmos. These beings can range from a Maruts to Archanaloths. Such creatures have great power of compulsion over lesser creatures.

Expanded Spell List

The Contractor 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.

Contractor Expanded Spells

SPELL LEVEL	SPELLS
1st	command, detect evil and good
2nd	warding bond, zone of truth
3rd	glyph of warding, sending
4th	compulsion, divination
5th	planar binding, telepathic bond

Oathsworn

At 1st level, you and your allies can swear an oath of protection to one another. When you finish a long rest, choose a number of willing creatures equal to your proficiency bonus (this can include you) to become an Oathsworn. As a reaction, you can spit the damage taken by one of the Oathsworn between another Oathsworn.

This effect lasts until the end of your next long rest or until you die.

Arcane Transaction

When reaching 6th level, you have learned to apply your contracting to the arcane arts. Oathsworn can donate knowledge of spellcasting until the Oathsworn feature ends. The donor can expend spell slots with a combined level of 5th or less, and the receiver gains those spell slots. The donated spell slots can only be used to cast spells from the donors spell list.

Sealed Mind

Starting at 10th level, you have become highly adept at guarding yourself from being compelled. You gain advantage on Intelligence, Wisdom, and Charisma saving throws against mind-affecting abilities or spells.

Binding Words

Starting at 14th level, you hold a creature to the bond of its word. As an action, choose one creature within 60 feet of you that has stated intent to do something. This creature must make a Wisdom saving throw against your Warlock spell save DC. On a failed save, the creature must perform the action they stated to the best of their ability or attempt to do the action starting on their next turn. At the end of each of its turns, the target can make another Wisdom saving throw. On a success, the effect ends on the target. This effect lasts for a number of turns equal to your Warlock level or until they have completed the action. 

Once you use this feature, you can't use it again until you finish a long rest.
