It's a fantasy role-playing game.

DM: You are Tiberius Stormwind, a dragonborn sorcerer . You are the member of the famous group of adventurers. Previously, The explosion rocks the vicinity, toppling the cart. A glass container that was in the back of the cart shatters.
DM: -- due to the darkness in this room it's very hard to see, other than the slight glow from the lava. So you fire all three rays, and you see them streak through, and each one gives off just enough light from the actual flaming ray to glow to the vicinity, but not the actual target. You see them both streak off and slam the wall on the opposite side.
Player: Wait, do I add my dex on those?
DM: You add your spell modifier.
Player: (whispers) What's my spell modifier?
DM: It's on top of your spell page!
Player: Oh! Oh, no, I'm sorry, 20-- plus nine on all that.
DM: Good to know.
Player: Yeah, sorry.
DM: All three hit. Go ahead and roll damage.
Player: Okay.
DM: There you go.
Player: Okay, first one does five--
DM: It's his first time casting spells, guys. (mouths) It's not.
