The Liar

The Lord of the Lies, the Master of Misleading, the Duke of Deceit. He goes by many names, none of which are likely to be true. What is true about your patron is that they are an embodiment of deception and falsehoods. Warlocks to this patron will never tell the truth, no matter how hard they're pushed, and gain additional magic means of lying.

I'd like to give a special thank-you shout out to user Jayne_of_Canton for helping me decide on the higher-level abilities for this subclass. Without their help, this subclass would not be where it is today.

Life of Lies

Starting at first level, you are incapable of making a true statement due to your arrangement. This also applies to writing. You can communicate without deception by way of questions, but you cannot make a true statement. This grants advantage to all deception roll, and a proficiency in deception. If you are already proficient in deception, you may select another skill to add your proficiency to.

Cloak of Deception

Starting at 6th level, your lies can protect you even when your body fails. When you fail a saving throw against elemental or physical damage, roll a deception check against the save DC. If your deception check succeeds against the save DC, you teleport up to 15 feet and avoid the damage entirely.

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

Dishonest Thoughts

Starting at 10th level, your mind becomes slippery, sometimes fooling even yourself. You are immune to the Zone of Truth spell. You have advantage on saving throws against being charmed or frightened and against any spells that try to discern your thoughts or emotions. Once per day, you may cast False Life at 5th level.

Power of Deceit

The power of your ill intent seeps into the weave of magic itself. You gain expertise in Deception if you do not already have it. If you already have it, you may gain expertise in another skill.

When you cast any spell that targets a single creature and that spell fails to hit or the creature saves against the effect, you may choose to immediately re-target the magic to a different creature close to the original target. A ranged spell may re-target a creature within 30 feet and a touch spell may re-target a creature within 5 feet. The spell then proceeds as normal but you may not re-target again if the spell fails to hit or the new creature saves against the effect. Once you use this feature, you cannot use it again until you finish a long rest.
