Crossclimb Level 5 is a 4-letter Crossclimb ladder from FAST to LAST. Phase one is crossword solving: 5 middle clues yield FIST, FISH, WISH, WASH, LASH. Phase two is ordering; phase three unlocks the combo ends tied by "Opposite of first".
Middle phase answers: "Closed hand" = FIST; "School of swimmers" = FISH; "Hopeful feeling" = WISH; "Clean with water" = WASH; "Strike with a whip" = LASH.
Ordering phase: the valid middle chain is FIST → FISH → WISH → WASH → LASH. This permutation is the only valid one-letter chain for these answers.
Link FAST → FIST: A→I at the second letter (FAST → FIST) (combo-adjacent).
Link FIST → FISH: T→H at the fourth letter (FIST → FISH).
Link FISH → WISH: F→W at the first letter (FISH → WISH).
Link WISH → WASH: I→A at the second letter (WISH → WASH).
Link WASH → LASH: W→L at the first letter (WASH → LASH).
Link LASH → LAST: H→T at the fourth letter (LASH → LAST) (combo-adjacent).
Complete ladder: FAST → FIST → FISH → WISH → WASH → LASH → LAST. The combo clue "Opposite of first" describes both end words together — "FAST" and "LAST" each differ by one letter from their adjacent middle rungs and satisfy the shared top+bottom prompt. Pattern: unique middle order — Only one middle permutation forms a valid ladder from top to bottom — if ordering feels stuck, recheck a middle answer.
