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, The damage quickly reverts them out of their eel forms. The fight comes down to simply destroying as many of the tentacles as they can, hoping this will allow them to get away.
DM: You watch as the spark of energy from the arrow hits it the second time, the daylight obstructing your view, and the energy bursts around it. The lightning damage you're used to seeing from any creature it impacts, the lightning seems to just hit its blubbery hide and vanish.
Player: Right, 'cause lightning-- it just did lightning. Obviously it's immune to lightning. Right. And I'm gonna use my motion to back the fuck off and try to get behind that rock outcropping. Laser pointer. Okay, yeah, sure. Just on the other side of it.
DM: That's as far as you can get.
Player: Okay, cool.
DM: Because you don't have your Alter Self form yet. You're like (swimming noises). You're slowly swimming through this water, sluggishly.
Player: Okay.
DM: As far as you get Trinket, you want to give Trinket any sort of movement on this?
Player: Yeah, can he back up behind that pillar?
DM: Right here?
Player: Yeah.
DM: Yeah, Trinket moves up and guards himself behind the side. All right. Percival.
