party after upgrading tb warden 2 summoners with huntress/monk guardians(running squire + warden on field with guardians can be faster by like 30 seconds to 1 minute but eh)
you will do chest routes on either one of the summoners but you should have one of your builders on hit 5 looking into the wall the entire game and when you are not doing chest routes your split should be fully focused on them(this saves 2 minutes)
my build setup + example of builder staring into the wall + fastest run with the double builder onfield setup: https://ibb.co/album/RGr35F
