Here is a playtest option for that feature: The Godcore Patron. The Godcore You made a pact with an entity that exudes aversion to authority, even to itself. They live within the gray place, the inbetween, the middle planes beyond the material, yet not in the higher or lower planes. It has given you power to break the order of the world, to strive to be your truest self, but not at the cost of others. It guides you, but does not lead you. It helps you, but does not coddle you. It empowers you, but does not intervene. You are a breaker of chains, an ear to the unheard, and a voice for the repressed. The more you strive to unlock the potential of the individual the more power will be rewarded to you. Godcore entities derive from the original eight creators of the blessed forms of metal, known as: the Puppet Master, the Maiden of Iron, the Rot Queen, the Blind Wolf, the Slayer, the Twisted Witch, Roach Father, and the Lord of Mayhem. Expanded Spell List The godcore you have chosen lets you choose from an expanded list of spells when you learn a warlock spell. Please select the spells from the Godcore Patron Spell Table. Ward of Solitude 1st-level Godcore Patron feature When there is no friendly creature within 15 feet of you, you may add 1 to your saving throws (up to a max of 4) for each hostile creature within 15 feet of you. At level 6 add this bonus to your AC. At level 10 add this bonus to your attack rolls. At level 14 add this bonus to your damage rolls. Banshee’s Wail 6th-level Godcore Patron feature You may use your action to unleash a devastating wail in one direction. In the direction of your choice, a 15 foot cone of destructive energy extends out from where you are. Any creature caught in the cone must make a strength saving throw against your spell save DC. Any creature that fails is deafened for a number of turns equal to your charisma modifier and is thrown 1d4 * 5 ft away. If they hit any solid object, they take 1d6 points of bludgeoning damage for every 10 ft they were thrown. Any creature that succeeds is deafened until the end of their next turn. At level 14, any creature that fails the saving throw also takes 2d10 points of necrotic damage and half as much if they succeed. Increase the number of dice by 1d10 for each level beyond level 14 your character currently is. At level 20, any creature killed by this feature rises as a zombie under your control unless the humanoid is restored to life within 1 minute or its body is destroyed. You can only control a number of zombies equal to your charisma modifier. You may use this spell a number of times a day equal to your charisma modifier. You regain all uses of this feature after you take a long rest. Beguiling Essence 10th-level Godcore Patron feature Whenever you cast a spell of level 1 or higher for each target of the spell you may choose to expend an additional spell slot equal to or greater than the level the spell was cast at. If you do so each target must make a wisdom saving throw against your spell save DC. If any fail, they are considered charmed by you for a number of rounds equal to your charisma modifier. This ability does not stack with other spells that cause the creature to be charmed, like charm person. If any target is immune to the charmed condition, this feature simply fails when used against them. Brutal Retribution 14th-level Godcore Patron feature If an attack from a hostile creature would cause a friendly creature to drop below 0 hit points, and you can see both of them, you may use your reaction to prevent that damage. If you do so you instead lose hit points equal to half the damage that would have been dealt, and deal half that damage back to the original attacker. Any damage dealt in this way is cannot be prevented or reduced by any feature. If the loss of hit points would cause you to drop to 0 hit points or less, you still deal the damage back to the original attacker. After you use this feature you must take a long rest in order to use it again.
