A little farming help

i have a cranuicopia and the old steigers (God Bless hoarder instincts) but im not sure on how to farmwith/build/use these 2 weapons. what power should i run? which floors to farm200+? what build should i go for to make this farming work? (i have been twister/manashield since day1 so new equipment bulds are really appreciated, i mean glasscannon/empower equips that i use usually are a bad idea for these weapons lol) thanks guys
