Huge 30 second improvement here! The old single segment was 14:58. I was never happy with that boss fight because I didn't get enough damage in for the minimum amount of cycles. Getting the "two dives" finish on Nigel & Sebastian by itself saved 10 seconds from the old run. This means the main stage was separately 20 seconds faster than the old run. Part of that came from smarter survivor strats, and the rest was just solid typesmanship.

[Note time varies slightly from SDA time to be consistent with previously timed runs]
