Build was successful, but had some weird things to watch out for. I had to restart the map until the East Island was my starting island, because I could not do the build on later waves (build timer keeps going down).
Each wave was, build quick, swap to TB monk and upgrade everything while you keep boost up.
Been playing with 1 split only, until final wave, where you can bring in as many TB monks as you have (I think I'm gonna make 4 TB monks for this map only). Really you could add more splits as soon as you have been to all 4 islands.
