Arcane Fusion

5-level Transmutation

Effectively, when you use arcane fusion you cast two other spells using arcane fusion’s 5th-level spell slot. When you cast arcane fusion, choose any 1st-level spell you have prepared and any 4th-level or lower spell you have prepared. Neither spell can have a casting time longer than 1 action. Both spells take effect in the order you choose, as though you had cast each of them in that order. You don’t expend any spell slots to cast those spells. Each of the chosen spells has its normal effect, including range, target, area, duration, saving throw, etc. If either spell requires a material component or other special cost, these must be used or paid as part of casting arcane fusion.
