You weave two spells together in your mind and release them in a single burst of magic.
When you cast this spell, choose any one 1st level spell you know and any 4th level or lower spell you know. Neither spell chosen can have a casting time longer than 1 Action. Neither spell can have a Concentration effect. Both spells take effect in the order you choose, as if you had cast them one after the other, using only one standard action, but you do not expend any additional spell slots to cast these spells. No upcasting effects take place, the spells are cast at the base level of the spells chosen.
Effectively, you cast two other spells, using this spell's 5th level slot.
Each of the chosen spells have their normal effect, including range, target, area of effect, duration, saving throw, and spell resistances as appropriate to the spell's level. If either spell requires a material component or other special cost, these must be used or paid as part of the casting of arcane fusion.
(* Whatever is required in the spells chosen.)
