What is the coolest combo you have ever pulled off in an actual campaign?

[LoyalPaladin]

Bard slaps him with Otto's Irresistable Dance (to the dismay of the ship's crew), follows up with a Grease spell, and the next thing the giant knows, he's plummeting to the battlefield, high-stepping it the whole way down (Otto's allows you to do nothing but dance for the duration, so no teleporting, spell casting, etc.).

He didn't survive the fall.

I'm sharing that with my D&D group. That's amazing haha.
