Why wouldn’t you just, like, spell-o-tape the wand to your hand? That’s the first thing I would do before a fight.
Nintendo came up with a solution so long ago
And no one in this magical world invented a magical way to attach the wand?
Remember Syriuses mother portrait?
Probably the same, but painful.
I always wonder what effect would the spell “Expellidentum” have.
Maybe a rubber band…
Expelliarmus isn’t a second year spell. They were taught it in second year in order to “prepare them” since, ya know, Voldemort had been to the school the previous year.
TBF, to combat Kedavra with a disarmer requires such a strong Expelliarmus that he might as well have returned a killing cirse
Imagine that hit someone directly, probably would have ripped the whole arm off.
