Spellcasting (Willpower)

Charisma is your spellcasting ability for your spells. You use your Charisma whenever a spell refers to your spellcasting ability. In addition, you use your Charisma modifier when setting the saving throw DC for a spell you cast and when making an attack roll with one.

You must use a wand as a spellcasting focus for your spells. Your spell slot progression is the standard for full casters.

Additionally, when you gain a level in this class, you can choose two of the cantrips or spells you know and replace them with two new cantrips or spells, which also must be of a level for which you have spell slots.
