Note: sound is turned off to save time, usually in combat.

Didn't spend an enormous time grinding out runs, and I recall thinking about 21:0X minutes would be possible, but the routing is as solid as I could make it without knowing any game-busting glitches. The main time losses are related to combat and, aside from being hard to react to, damage appears to be RNG-centric, so good luck to anyone wanting to get a lucky amount of swings.
