My favorite spells and why starting from the most favorite.

Accio: it can find lost things, bring things from lost places and in some cases be a disarming spell

Expecto Patronum: it's a reflection of your soul, can ward off those pesky dementors, and it looks beautiful. Plus it can be used as a messenger.

Lumos: brings light to dark places

Imperio: u can control people to do your bidding or just make them humiliate themselves 😆

Expelliarmus because it's my signature spell

Lumos

My favorite spell is Expelliarmus because it can make the wands fly away from the opponent before it can cast a spell

Wincardium leviosa...i would love to make things fly...
