I tried stacking alz drop amount, but alz drop is capped at 30k -.- No mob can drop more than 30k alz, so it's pretty useless. Still, in ruina station I could farm like 1kk/minute, ~25kk in a 30 min run. That's 50-55kk in an hour, and you only need to run to statues and use macro to kill them with cannons.
Conclusion: Using this bug is useless IMO. You would need to run your pc all day to farm 500kk, that worth 5€. Electricity costs more -.- and there is a chance that they will remove the alz and ban you.
Only way to make money with this bug is to try your luck in ft3 for mazel ring, if it drops, find a fool and sell it fast, then find another fool and sell the alz for euros. They will remove the ring sooner or later I'm sure.
