It's a fantasy role-playing game.

DM: You are Vex Vex'ahlia, a half-elf ranger . You are the member of the famous group of adventurers. Previously, Then Tiberius uses Telekinesis to slam one ogre into the other and they are both knocked prone. Tiberius turns to Grog and yells,  They're all yours, buddy.
DM: Okay. You pull out your arrow and as you pull it back, a little bit of energy courses through your fingers, strikes through your arrow. You can now see this crackling energy as you're pulling it taut in your bow. You let it loose, roll for attack.
Player: Okay! 21!
DM: 21 hits.
Player: All right. Then I do something else. 1d8. Right?
DM: Yep. You do the damage of the arrow plus the damage of the spell.
Player: Holy moly! So that's this. 13 for the arrow and then 4d8 for the spell. (counting) 17!
DM: 17. Okay. The ogre that's been beaten, blasted by the fireball, it's getting up-- (grunt). It grabs its club, and it begins to get up on one leg as the Lightning Arrow slams into its chest. You can see it hits. Looks down for a second, and then the charge pulses through its entire torso. As it does, it screams out, "Ugh!" into the cavern, its whole muscle system locks tight and it falls forward again, onto its chest, smoke rising off of its whole upper area, unmoving, on the ground. He is gone.
