Climax (rhetoric)
A sequence of terms of rising (or falling) intensity that builds the sentence's power.
Rhetorical climax orders a series of words or phrases by rising intensity (or falling, for anticlimax): "I came, I saw, I conquered." Each term outdoes the previous one and the sentence becomes a launch ramp.
It is a figure of energy: it mimics rage, panic, enthusiasm. It demands real progression — three near-synonyms dumped together make an accumulation, not a climax. Term order is everything: the strongest closes the sequence, unless you want anticlimax, where the final drop deliberately deflates the build-up for comic effect.
Example
"I came, I saw, I conquered."
