Go to chaos, build a base for 8pc and 6ac and spam wisps with 1050 wood gain per second or go to coliseum and collect pc while gaining some xp, by the way you can go to coliseum with 0% and still get gold with some pcs tho.
if you have a group you should go colo very hard, else you just should buy a demonic nation in chaos world, then join another game and farm in normal world and go afk for a few hours

it is very simple, just kill savior 1st thing, and make sure that your whisps are out side of normal monsters range, or behind some obstacles and unreachable.
P.S. he is talkin about normal world, not hell meaning that sin's are of no problem to your whisps
