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: So you can make it. We'll say that's as far as you can get, no reason to hide, you're still out in the open, you don't have anything to hide behind, unfortunately.
Player: Can I sit on the ground? I wanna sit on the ground and wrap my cloak around me and make myself look like a rock.
DM: Actually, you do back up into the ink cloud, so you can.
Player: Hey!
DM: Which is not obscured to the kraken. So, you cannot hide. He can still see you in the ink cloud.
Player: Oh really?
DM: Yeah, so--
