If you need more details on how to get this setup to work see my other vids on NO Eggs gold farming, this is same setup but with smith.
Smith can be over powered when lvl'd up cuz he gains 0.7% of all 4 stats (might, area, duration, speed) and 0.25% CD +lots of luck.
This version will be harder to start off but not to hard, the bonus is you will be immune to reaper hits cuz CD will be so high and will be higher lvl then trouser. The drawback is you will gain less gold per min, average test show trouser gets 80k/min and smith 65k/min, but of course you can farm as long as you like and move freely.
SO if you can't get trouser no egg farm to work you some some unknown reason, this method should work.
