"Most" followed by multiple adjectives - does it refer to them all?

Solution 1:

The superlative marker most can distribute across any number of sequential adjectives:

Ferocious Competition: At the heart of Puyo Puyo Tetris is the fighting spirit of players competing against each other to be (the) most clever, cunning, and quick-witted one to set up devastating attacks on opponents. — GameDeal.it

This means most clever, most cunning, and most quick-witted.

The superlative ending -est does not distribute, so if you want a sequence of superlatives, you need a most after an -est:

Goblin chieftains are often the cleverest, most cunning and violent members of the tribe. — Christian Broadhurst, Raging Swan Press, 3 Aug. 2017.

They'd always kept the television in the tomb and, as a consequence, had spent most of their married life sitting in the darkest, ugliest, and most claustrophobic room in the house. — Stephen McCauley, Easy Way Out, 2012.

And if the sequence is interrupted by some other element, most can be repeated:

There is, in the very idea of this awkward political dance, the cleverest, most cunning and, in the end, most profitable of tributes being paid to the inescapable weirdness of America's electoral system. — Bernard-Henri Levy, CBS News, 11 July 2008.
