Its a cast "on touch" or "on self" not really a "on target" kind of wand.

It's, "leviosaaaaaaaaaaahhhhhhhhhhnnnnngggg".

RTFM

I put on my robe and wizard hat

It's great for casting "spell of weak legs"

If you know the somatic component, you can cast Discombobulate.

If you're casting it on someone else, verbal components can heighten the spell, but the exact incantation varies by target.

Pairs well with a Rabbit though.

Give it some time to do its job and it'll cast Power Word: STUN, no saving throw.
