Occult Adaptation

Not all Warlocks ask their patron for known magic. Some instead seek to gather more knowledge of the occult and the unknown.

When you reach a Warlock level where you would gain a new Spell Slot (2nd, 7th, or 11th) you can instead learn two invocations.

Additionally when you gain a level in this class you can choose to reduce the number of invocations you know by two to gain a new spell slot. You cannot have more spell slots than are shown for your level in the Warlock Table
