[Run taken from my Any% run, and re-timed for accuracy]

I'm not 100% sure how manipulatable Frostwind's second phase is, but it went pretty well for me in this run. I'll take it! (Also, fun fact: did you know the boss levels have actual names? It doesn't say the names on the map screen, the Mayor just says it once before the boss fight! Frostwind's is called "Snowy Snow Mountain".)
