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, Kima happily tests out her new paladin sword. you goes down to the training area to test out her staff.
DM: All right, you four head down to the training room. Kima comes down to watch as well. Pike comes down, eager to watch what this new artifact does. You head down to the training area. You have the big sandpit that's cordoned off with the wooden outskirts, you have the various dummies set up in certain ways, you have the portion of the room that has the armor stand on the side, the weapon stand. What do you want to do?
Player: Ooh-hoo. Okay. All right. Everyone stay back. I'm going to start by casting the lowest level of spell out of it, see what it does.
DM: Which is?
Player: Apparently a Fireball.
DM: Okay. At where?
Player: Whatever is further in the sandpit. I told everyone to stand back.
DM: Everyone stays back. Furthest part of the sandpit is going to be one of the various combat dummies. So you launch-- put the staff down, you guys watch as in the centerpiece at the top, where that one gem is hovering and slowly rotating in place, the gem begins to glow bright red from its soft bluish-green composure. As it hits bright red, this beam of familiar red arcane energy streaks forward, hits it and detonates into a shaking explosion, destroying the wooden dummy and singeing the one immediately left to it.
