Mostly Afkable (last wave you might want to be there) build I made after seeing Luchador build. the building will all take place on first floor and really only need abt 4k mana first build wave to have build done+ maxed out buff beam. I used a summoner with guard+monk to boost auras after wave 5. but on wave 5 i maxed out physical beam. it works well and it has yet to fail me. also all defences will just be pointing forward or away from forge.
