Changes: Removed reflect beams, the owls nest is killing the spiders anyways. Added the seed tower. It seems incrementally faster, so incrementally less painful. Seems very stable and afk-able. I usually put the seed tower as close to the mana box as it can, and then stack everything else as close as it will let me behind it (Warden, Squire, Mage). Then put the buff beam down, check for 11 towers, then put the golem down (check for 12 towers buffed cause he's weird sometimes).
I'm mostly about 5-6k (monk is 6k, almost all else is in the 5k range) in the relevant stats for each builder class.
I boosted with two app/huntress summoners and used the TB monk and afk'd for house chores. :) It lives without the TB as well, and the bonus is at the end when the genies and sharken show up it looks like a Rave. So there's that.
