It's a fantasy role-playing game.

DM: You are  Kashaw Vesh, a human cleric . You are the member of the famous group of adventurers. Previously, Hotis then attempts to flee but is held back by Tiberius. As the team assault him, a suit of armor animates and comes to his aid, hitting them all with a stored Fireball.
DM: All right, so. That is the creature's turn. It finishes its spell, pulls back. However, the gem goes to a dull, dark state. No more stored magical energy. Kash, what are you doing?
Player: I've got to heal myself, unfortunately, because I'm getting down there. So I'm going to Cure Wounds.
DM: Okay. At what level? You can cast it at a higher level.
Player: I know. I'm not sure I want to, yet. You know what? I am. I'm going to Mass Cure Wounds right now, just because I'm so low.
DM: Okay.
Player: So it's level 5.
DM: Okay, so Mass Cure Wounds.
