Wondrous Recall allows the caster to restore to memory two previously cast spells from their spellbook.
Higher level spells will take priority in the restoration queue over lower level spells. Since the spell simply checks the spellbook for used up spells, you can even pick different spells than the ones you've cast, and the Wondrous Recall will still restore them. You can even pick spells during the casting animation.
