wsopboy91 maintains a crib sheet of the latest details on damage ranges, routing concepts, etc for the ice beam route which is crucial for top play

Introductory route from HwangbroXD (very low variance, benefits from lots of saving, can't record)

Additional details on the ice beam route from Wavewarrior (current WR uses this)

A higher variance route using blizzard is competitive with the ice beam route and has traded WRs with it historically.  It has even higher variance than just blizzard's accuracy because it relies on risking more mansion encounters.
