Voice of Authority

You can cast the command spell at first level a number of times equal to your warlock level. You regain all expended uses when you complete a long rest. At fifth level in this class, you can do so at will. Your command spells can affect undead and those who cannot understand you so long as they can hear you.

Further, you gain proficiency in the persuasion skill, you add double your proficiency bonus to checks you make with it.

Objection!

At 6 level you gain the power to annul the fates themselves, whether to undo a wrong, or right an injustice. Whenever you or a creature you can see within 60 feet succeeds on a saving throw or ability check, or hits with an attack roll, you can use your reaction to force a reroll on the saving throw, ability check, or attack roll.

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

Court Order

Starting at 10th level, your mastery of Mystic Law allows you to exert your authority over other creatures and bind them to your will.

You can cast the gaes spell without expending a spell slot. If you do, you cant do so again until you complete a long rest. You can cast gaes as an action, if you do, its duration becomes 30 minutes. 

Further, you can cast gaes at a higher level by expending your Mystic Arcanum of that level to do so.
