Witchwarper: Quantum Thesis

You command the most potent magic and can cast spells of truly incredible power. Add two common 10th-rank spells of your tradition to your repertoire. You gain a single 10th-rank spell slot you can use to cast these spells, using Witchwarper spellcasting. Unlike with other spell slots, you can't use 10th-rank slots with abilities that give you more spell slots or that let you cast spells without expending spell slots. You don't gain more 10th-rank spells as you level up, but you can take the Quantum Research feat to gain a second slot.
