DM: You are Nott the Brave, a goblin rogue . You are the member of the famous group of adventurers. Previously,  Before this happened, as a part of a journey towards this Tri-Spire, both Caleb and Jester made their way there. Caleb unsuccessfully entering a nicer district of the city that did not seem to believe or respect his presentation.
DM: So (fwoosh), and as you throw your orb, it skitters up the wall. You almost hit it, but it pulls out of the way before it shatters, the orb splattering acid across the stonework, burning through whatever outer layer of thick liquid has congealed there.
Player: From where I'm hidden to where it was when it appeared, how far is that?
DM: From where it appeared? That would've been 40 feet from you.
Player: So I have to roll with disadvantage?
DM: Yes, you do.
Player: Ooh, not as good. 11.
DM: Goes wide, no impact, unfortunately. That ends the spider's turn. Beau, Molly, you're up.
