Fuse Spells

Level 20

You can combine lower-level spell slots to cast higher-level spells. As part of casting a spell, you can spend 1 Resolve Point to exchange a number of unused spell slots for a single spell slot of a higher level; this expends the lower-level spell slots. Add up the levels of the expended slots to determine which higher level of spell you can cast (maximum 6th). For instance, you could exchange three 1st-level slots to cast a 3rd-level spell, or you could exchange two 3rd-level slots to cast a 6th-level spell. If you combine spell slots to cast a 6th-level spell, it doesn’t count as such for resolve attunement.
Furthermore, you can spend 2 Resolve Points to combine two 6th-level spell slots to cast wish.
