I don't think it would be a specific spell, but it would probably be that I'd use Transfiguration spells more often. Melofors, Pullus, that sort of thing.

The Knockback Jinx

Levicorpus and Reducto

Muffliato

The Aveda Kadev...

I mean cruci...

Imper...

JUST ALL OF THEM

Scourgify. Because I hate washing clothes and utensils and even myself.

Expecto Patronum!

...because I'm shrouded in darkness and depression

Stupify because... I honestly don’t know, it’s just my go-to for some reason XD

Impedimenta or Everte Statum

Imperio-

Don't ask why
