Wait, didn't Dad Aurion warn about Arcane and Blood Magic being dangerous if you aren't careful? (meaning, keep it well away from Sam!)
Wind spirit magic...I don't know why but I have this image of Siofra summoning one, then the MC summoning one and they argue over which one is better/cuter and instead of the multipart fight it's a pokemon-style fight where the better wind spirit wins! If it's Siofra she does this "YES!!! I'm better, neener neener", she takes youe wind spirit, then you have to fight her as normal!
