It's a fantasy role-playing game.

DM: You are Fjord, a half-orc warlock . You are the member of the famous group of adventurers. Previously, Caduceus, on fire and concerned that Caleb and Nott still have not shown up, cast Meld Into Stone on himself. He became part of the wall and put out the fire on himself.
DM: Nice. It gets hit twice. I'll say, go ahead and make an intimidation check. Just as part of this attack, since this was your intent.
Player: 21.
DM: You have the dragon's attention. He was slashing into Jester, and after that, twice in the side of the head, it (growling) back towards you.
Player: Do I have to roll blink if I don't--
DM: You can choose to end the spell.
Player: But I think, doesn't it take an action or I can just choose?
DM: That's a good question. Let's go ahead and check. It should tell you on the spell.
Player: It says, "you can dismiss this spell as an action."
DM: Ah. So no.
