hi I played L2 retail from Beta til IL with up to 4 accounts full botting from 60- 78/79 when i left retail.
This is how it works
1. be anonymous (no Clan, dont ever shout and make others hating u)
2. use INGAME L2W and watch the chars/client as often as u can. Use Spots with no Farmers (there are special Farmer/Botplaces to FARM items) try to be "alone".
3. Know how to setup L2W... f.i no autorezz, use auto-log off when ur char is dead and there are like 10 Musts for L2W adjustment)
4. Buy very cheap Accounts at min level 61 for like 50$ with some equipment...starting form zero is
