Party: 1 TB monk, 1 builder warden (undrer the bridge), 1 HB monk, 1 DPS monk; for boss, I place all guys under the bridge except the DPS monk, but you can do whatever.

Wave 1, build auras and buff beam, and golem and pylon, then some of warden build and keep warden in during combat to finish warden build, all set.  Use an upper jester, or TB and upgrade as you go.  For most waves, just keep warden in and TB.  Then on boss wave bring in the HB monk and DPS monk (I have both with eye pets), can have them stand on top of golem or under the bridge.  But do keep builder warden under the bridge.  On boss, active all boosts (TB, HB, and Warden Wrath), should drop boss super fast and net 4 spears.  Yea, the boss just melts, like maybe 10 seconds, was nice.  Ran with the secret and both bosses dropped super fast.  Good luck.  Might actually speed up wave times to keep 4 splits in?  Maybe have some summoners in for the regular waves.

TEST RUN

2:55 BUILD TIME

12:03 COMBAT TIME

Hmm, not sure what to do to make it faster.  Maybe remove slow auras?
