1: Make Minion walls however you like basically just healable walls just make sure you make them 2nd wave and have at least 1 mage and the archers can tank on top of the EV Buff Beam.
Wave 1:
Huntress Traps, Strength Drain, Buff beams
Wave 2: Minions as much as possible, Try to place some of the DST near the forge if possible, Beware wyverns
Side notes: Beware wyverns can get a little hectic and also spiders can sometimes mess with the two right side crystals Id just stand between that little Alcove and ensure u shoot down Ogre Copters and stop spiders from messing with DST getting the Wyverns.
I used Jester to DPS off wyverns and heal cores if I was ever being sloppy but if your Summoner has even semi decent minion damage you can easily make up for the DPS I had to do personally.
