Base Class: Warlock
The Masked Crown is not a singular being, but a mantle passed between those that share its distinct power. It is a lawful being that punishes those that break its rules, exposing those that hide themselves to meet the judgement of its council. It, however, will use its laws to complete whatever goals it so desires, changing the law on a whim to suit their needs. The Masked Crown always follows the laws; The ones made by it.
Crowned Chaos
Starting at 1st level, the bond with your patron allows you to utilize a piece of their power to alter the world around you with volatile, unpredictable magic. Whenever you cast a spell of 1st Level or higher, you must make a DC 8 Wisdom Saving Throw. Whenever you succeed on this saving throw, the DC increases by 1 to a maximum of 15. When you fail this saving throw, roll on the Wild Magic table; The DC for the saving throw then resets.
Invoke Chaos
Starting at 6th level, your link with your patron allows you to summon their chaotic presence to your realm. As an action, you can summon a visage of your patron in an unoccupied space within 60 feet of you. For 1 minute, you have advantage on Wisdom saving throws to against your Crowned Chaos feature. Additionally, for the duration, all creatures within 30 feet of the image are under the effects of your Crowned Chaos feature and must make a Wisdom saving throw against the DC for the feature whenever they cast a spell of 1st Level or higher. This feature can only be used once per long rest.
Rewrite Reality
Beginning at 10th level, your patron has begun to whisper its secrets in your ear, spinning the works of its power for you to hear. As a reaction when a creature within 30 feet of you fails a saving throw or check, you can make a DC 8 Wisdom saving throw. If you succeed, that creature can make the saving throw or check again and uses the new roll. Additionally, whenever you succeed on using this feature, the DC increases by 3 to a maximum of 20 and resets when the saving throw is failed.
Law of the Crown
Beginning at 14th level, your bond with the Masked Crown has given you a seat at their side and a share of their power. You can use the effects of the spell, Counterspell, once per short rest. Additionally, if you interrupt a creature's spell with this feature, you can make a Wisdom Saving Throw with a DC equal to 8 + the spell level. If you succeed, you can cast that spell once on your turn, losing the ability to cast it using this feature immediately after casting it. Alternatively, you can hold the spell for 1 minute and for that duration, the creature you interrupted cannot use the spell. You cannot cast the spell during the duration if you decide to hold the spell and you cannot cast the spell at the end of the duration. If you fail the saving throw, roll on the Wild Magic table with disadvantage.
