It's a fantasy role-playing game.

DM: You are Keyleth, a half-elf druid . You are the member of the famous group of adventurers. Previously, Judging by the weather, they have arrived somewhere in Exandria. As Vox Machina comes within range of the base of the tower, they are addressed by an omnipresent, directionless voice.
DM: Delilah's over here. She and two skeletons right now are lording over the paralyzed Vax on the ground.
Player: If I move at all, I'm going to take opportunity from skeletons.
DM: Yep. They don't do a whole lot of damage, but damage adds up.
Player: Jesus. Okay, I am going to head to Delilah. I can move up to her, correct?
DM: You're going to move straight up to her?
Player: Can I?
DM: You can, yeah. Both skeletons get attacks of opportunity on you. That's a nine and a 12. They both hit you, but the mantle writhes out in front of you. You watch as various leaves unfurl almost like a cat's fur on the back of its neck, and it deflects the blows from the skeletons as you rush past.
