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, Grog then takes the first bead of divinity -- the one from Ioun-- smashes it on the Anvil, and folds the powdered remains into the first ingot. With aid from you and Scanlan in the form of spells and inspiration, he does the same with the bead from Pelor, but has trouble with the one from the Raven Queen.
DM: So as the blade arcs overhead towards you, you barely duck out of the way. It slams on the ground, sending shards of stone and metal up in the air around you. You feel it rain over your shoulder and the back of your head as you slowly pull away from it. All righty, now it is the elemental's turn.
Player: Okay, it's going to move over to him. And he's bigger than large, so he's going to do a multiattack. He's going to do two slam attacks. Plus seven to hit. (groans) One's a natural one; the other's a natural 18. So one hits. 2d8 plus four bludgeoning damage.
DM: What's the attack? 18 plus?
Player: 18 plus seven.
DM: Okay, so it would be 25? That hits. Are the creature's attacks considered magical?
Player: They're two bludgeoning attacks.
DM: Nowhere on there does it say it does magical damage?
Player: It just says bludgeoning damage.
DM: Okay. So as the elemental swings out both fists against it, no effect. None of its attacks seem to have any effect or impact on the creature. It's like bludgeoning the side of a mountain.
