I've had 10 seconds better for the first split so with good luck in the later battles 53:30 shouldn't be an issue.

Possible timesaves/RNG notes:

• Talon - Fight can be done in 2 hits if you get a Slam and decent damage rolls (saves 6 seconds over the 4 hit version)
• Zog - More kisses = less time. His 2 fiery attacks both lose the most time.
• Jade - Not getting the StarSH saves time, but if you get hit by shock the run is over. Ball or Dust are fast and you can get away with one heal if he doesn't T.Bolt you.
• Tyr - I don't think you're ever going to get a single heal fight, so there's not much variance here.
