dude this build is so fucking funny. it makes me wanna stack without looking.
My stats are 7k+ but you can definitely use it with much lower.
For Ruthless, have a TB out shooting at any lane. Guardian pets are good here (as always).
If you're farming weapons on RL survival, you can do 1x TB + 3x (insert character you want the weapon for, which is probably 3x apprentice for canes). Just up during wave 32 with an adept. Also, it's faster to always have 4 splits in here.
Faster than seed bombers by a considerable amount. Hell, you could probably go without the Hermit Towers. I'm not gonna test.
