The ideal rebuttal against expelliarmus
Certain spells in Harry Potter appear to be absolutely ineffective. Others, on the other hand, appear to be simply fantastic. When we first discovered the franchise, we considered expelliarmus to be one of the best. It scatters your opponent’s wand, preventing them from casting spells.
That sounds fantastic! However, we can’t help but wonder why no one thought to just put a wristband on the wands. Isn’t that going to make expelliarmus useless? It’d be similar to the Wiimotes bands. It’s good enough for Hogwarts if it’s good enough for Nintendo.
