Can Ariel use Silvery Barbs on that? :hmm

You can indeed use Silvery Barbs on one of those rolls. ^_^ 
It will consume a spell slot.

Yes, I know. I'm just making sure I'm doing correct DnD combat choices... since I only have a little time before I have head to work.

One more question, I just need to roll 1d6 for a short bow attack? Wait I need to roll something to see if it hit, right?

Whoops. Sorry! ^^"

But yes, roll a 1d20+4 (Dex mod + Proficiency Bonus) to see if the short bow attack will hit, and if it does, then you can roll a 1d6+2 (Dex Mod).
