Pact of the Perfidious
Prerequisite: non-good non-lawful alignment
At 3rd level, your patron favors your attempts to convince, deceive, or mock, as you prefer.
Choose one of Deception, Intimidation, or Persuasion, you gain proficiency with the chosen skill if you do not already have it. Once per turn you may re-roll a failed check with the chosen skill; this benefit can be used a number of times equal to your proficiency bonus per long rest.
Additionally, you gain Friends as a free cantrip that does not count against your limit and is a warlock spell for you. You may cast this spell as an action at will, without need of a spellcasting focus or spell components. When cast by you, Friends has a duration of Concentration, up to 10 minutes, and when the spell ends the target must make a Charisma, Intelligence, or Wisdom saving throw (their choice) against DC 12 + half your warlock level (rounded down). On a failed saving throw the target does not realize that you used magic to influence their mood. You may not replace this cantrip with another.
Eldritch Invocations
The following eldritch invocations are available to warlocks with this Pact.
Perfidious Attack
Prerequisite: 5th level, Pact of the Perfidious feature
You know how to strike subtly and exploit a foe’s distraction. Once per turn, you can deal an extra 2d6 damage to one creature you hit with an attack if you have advantage on the attack roll.

The attack must use a finesse or a ranged weapon. If you have the Sneak Attack feature as well, this invocation is equivalent to and compatible with that feature (i.e., the extra damage stacks).
