What does fellest mean?
"Fellest" is the superlative form of the adjective "fell," an old and distinctly literary word meaning fierce, cruel, or deadly. To call something the "fellest" foe, storm, or deed is to declare it the most savage or merciless of its kind. The base adjective "fell" descends through Old French "fel" (wicked, cruel), which also gave English the words "felon" and "felony," linking the vocabulary of savagery to that of crime. Though "fell" itself survives mainly in fossilized phrases like "at one fell swoop," its superlative is rarer still, appearing almost exclusively in poetry, historical fiction, and archaic pastiche. Writers reach for it when they want a heightened, medieval flavor that everyday comparatives like "fiercest" cannot supply, but in ordinary modern prose "fellest" would strike most readers as stilted or antiquated.

Etymology of fellest
"Fellest" is formed by adding the superlative suffix "-est" to "fell," an adjective borrowed from Old French "fel," meaning wicked, cruel, or treacherous. The Old French word is generally traced to medieval Latin "fellus/fello-"-type forms connected with villainy, which also yielded English "felon" and "felony." The adjective was common in Middle English and flourished in Renaissance verse before fading into archaic and literary use.
