This is a metapuzzle, so first we collect answers:

  • The Jig is Up: X IS WORD Y IS LETTER
  • The Chess Fairy: COMBINE PERMUTATIONS
  • The (x, y) Conundrum: FLY A COMPLEX PLANE
  • Word Scramble: PERMUTATORIAL EXPLOSION

Then, we notice that the dictionary entry for “extraction” matches the online Merriam-Webster dictionary (as of April 2021, at least). Each of the 14 items says a word or phrase to look up, followed by text about what to do next. How to interpret the text depends on the extraction method of the corresponding puzzle.

Chess puzzle solutions:

Moo (Knight that can't jump over pieces). Fd6#.

Frog ((1,1)-leaper + (0,3)-leaper). Fe1#.

Gnu ((1,2)-leaper + (1,3)-leaper). Fe2#.

Princess (Bishop + Knight). g6.

We put the letters we extracted in the order specified by the enumeration to get VANEMON EXTRACT.
