Pinkie Pie: Alright! I use my other Majestic Word on Rarity to heal her back up! The brand new Majestic Word is "showtime"!
Rarity: I couldn't agree more, Pinkie. Shall we show this wannabe king who really rules around here?
Rainbow Dash: Dang it, I was gonna do the awesome pre-beatdown one-liner. Had one saved up and everything.
DM: You… can still say yours.
Rainbow Dash: Moment's passed, genius. Hers was better anyway…
Blueblood: No… NO! I have worked too long and too hard for this! I'll destroy you before you ruin everything!
DM: He swings at you with a powered-up Unstable Strike.
Rarity: I use a Swift Parry to buff my defenses.
DM: So… you took his last-ditch magical point-blank attack… and completely deflected it. Lovely.
Twilight Sparkle: I think I have the perfect setup for the final strike! I cast Symphony of the Dark Court!
DM: Oh boy, let's see… Each ally in the burst can shift up to 4 squares and gain +4 to damage rolls until the end of your next turn.
Pinkie Pie: This is the best song ever!
DM: And Blueblood is dazed and immobilized, save ends both. As if he wasn't granting enough combat advantage. Which means the question really boils down to: How do you want to finish it?
Rarity: Say… Could a glass slipper be an improvised throwing weapon?
DM: I suppose so?
SFX: (BACKSTAB!)
