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, He pulls out Bad News and swings it like a bat, bludgeoning the entity and thankfully not damaging the gun. The entity strikes back at Percy, missing the first swing but hitting with the second.
DM: No, the dodge is not there. It rarely came into play. Okay, so that puts you at another 15 points of bludgeoning damage as it just smacks you right across the head. Your eyes go dizzy for a second, and you take a minute to refocus your vision, and you can now see in the air, the shimmering expression that looks like a humanoid face stretched and ghastly going (gasps) in front of you, but it's still barely even visible, and only because of the proximity to you are you able to actually make out any sort of shape or shimmer in the air in front of you. The other one is attempting to choke out the prisoner. However, the prisoner resists through athletics, so he's currently holding back at bay the strength of the entity. That ends its turn. Trinket's up.
Player: Trinket's up! He's going to try to jump and land on top of the ghostly thing and bite its face. I don't know how to do that.
DM: To do a real leap, Trinket would have to back up and then run towards it. If Trinket wants to do that. Okay. So Trinket backs up. As it does, it gets one free swipe at Trinket. That is 18 to hit.
Player: I'm having an issue here. Because I have 18 in parentheses, and then I wrote a 20 and I circled it and I don't know why.
DM: I don't know why, either.
Player: 18 is probably--
DM: Yeah, we'll say 18. So that hits. Trinket takes 15 points of bludgeoning damage as the entity swings out and backhands Trinket. However Trinket now leaps-- go ahead and make an athletics check.
