C2 idioms: a Pyrrhic victory (a win that costs too much), a poisoned chalice (an attractive role that brings trouble), the elephant in the room, to have skin in the game, to move the needle, a watershed moment, to damn with faint praise.
Variation and play: proficient users adapt idioms: not so much a poisoned chalice as a poisoned buffet; the elephant in the Zoom call. You must know the original to understand the play.
Truncated proverbs and allusions: native speakers often say half: When in Rome… ; Speak of the devil… ; It’s a case of the emperor’s new clothes.
Clichés: overused idioms (at the end of the day, think outside the box, a perfect storm) weaken careful writing. Use idioms that add precision, not filler.

- The promotion proved a poisoned chalice.
- It was a Pyrrhic victory: the party won the vote but lost the election.
- Nobody mentioned the budget — the elephant in the room.
