Hint 1 - ***Build Warden towers during wave***. (far back of BB)
Hint 2 - TB this stack during non boss waves.
Hint 3 - Make sure towers have LOS of stairs or else archers will shoot crystal.
Hint 4 - 1 Character sits between towers and bbs to help with arrow agro. (this can be a Loot character with Huntress guardian, or DPS if you want to make it go a bit faster)
Hint 5 - TB stands behind rock for boss so it doesnt get targeted by cupid arrows, TB reaches towers if high enough.
1 Physical beam on far front of BB, the other infront of it, NOT on BB.
Arrows:
Green - Sludge Launchers
Blue - Clouds
Black - TB shooting for mana

*NOTICE*
You do not need a high guardian for this build at all, Bulwarks dont increase healing the more THP you have, therefor you dont need super high stats for her. (ofc more thp means they are a bit tankier, but it isnt super needed)
