It's a fantasy role-playing game.

DM: You are Grog Strongjaw, a goliath barbarian . You are the member of the famous group of adventurers. Previously,  Some of them splintered off to try and acquire the goods that were taken from his store, however they apparently had already been stolen from the location they were being stored in, or been delivered already, they're uncertain as to what became of them. But they get the sense that it was probably best that they chose Gilmore over the gold, at first glance.
DM: 22. So you rush forward, slam the sword into the side of the lizard creature. It puts its shield up and it manages to block most of the blow, but it still slides off and slams into part of its neck area. It shoves the blade out. However, it fails its save.
Player: Yes!
DM: Take a strength point off of it and add that to what you have now. What's your strength currently?
Player: 22.
DM: So it goes up another plus one to attack and damage. If it became 22, it does.
Player: Yes.
DM: All right. Grog, that ends your turn. Vex, you're up.
