A few spelling mistakes: acCio, episkEy, expelliaRmus, impedimEnta, orchideUS, serpenSORTIA, stupEfy. You might want to change the definition of "Cave inimicum", it is a magical warning against enemies ("cave" in Latin means "beware of"). Otherwise, great and challenging quiz!
ACCIO not acio
ESPISKEY not espisky
EXPELLIARMUS not expelliamus
IMPEDIMENTA not impedimanta
STUPEFY not stupify
Nice quiz :)
