Pact of the Cauldron

You have a magical cauldron granted by your patron. You can use your cauldron to create a number of potions up to your Charisma modifier (a minimum of 1) over the course of 10 minutes. When consumed, you can use your reaction and expend a warlock spell slot to empower the potion, otherwise the consumer must succeed on a Constitution saving throw against your spell save DC or be targeted by the disguise self spell (you determine the consumer’s new appearance). A creature can choose to fail this saving throw without rolling. If you expended a spell slot, choose any warlock spell you know with a range of Self or Touch and the creature who consumed the potion is affected as if they were the target of the chosen spell. Once you create a number of potions equal to your Charisma modifier (a minimum of 1) with this feature, you can’t create any more until you finish a long rest. Potions made with your cauldron become inert and impotent after 8 hours. If you ever lose your cauldron, you can perform a 1-hour ceremony to receive a replacement from your patron. This ceremony can be performed during a short or long rest, and it destroys the previous cauldron. The cauldron melts into sludge when you die.
