The easiest way for me is :
Method 1
1) Make a spoiler
2) Spoil (Bot)
3) Craft with what u have spoiled
4) Sell what u have crafted
Method 2
1) While botting use L2w for auto seeding.
2) Sell the seeds at Manor
3) Sell the mats you get.
Method 3 (PVP server)
1) Make a warlord, get a good pole, good buffs & go farming.. Aggro mobs like a maniac.
Method 4
1) Bot quests for recipes & sell the recipes, Top A Armor recipes. You can also trade this for other recipes.
Method 5
1) Bot for EAB's in Frozen Labrynith ( The antelopes) ..When u have some, over enchant B equip, about +6
and sell it to noobs for lots of money..
Method 6
1) Farm AA, & sell it a little cheaper than what others sell it for.. u will be sold out quickly..
Method 7
1) If you have a good high lvl char u know to power exp with, then all u need is some rich guy who has a sub
within 20 lvls of ur char. Offer him that u 'll exp him for some cash.
Method 8
1) If you wanna follow rulez then then go do the hatchling quest & sell those babies or sell them as striders ...
IMO the best way is botting, I 'm bad at scam ^^
Method 9 For New Players
1) Make a spoiler, at lvl 20 u can spoil steel at the best chance in the game, even high lvl spoilers cant spoil steel faster than u, spoil steel & sell steel, botting for steel is like icing on the cake.
