The only way to gain adena is using Sayhas Grace, because if you have 0% of Sayah's Grace mobs dont give you adena. So, you have to pay real money to gain adena. in 23% Sayha's Blessing i gained 6 Lcoin and buy a Sayahs Bottle cost 20 Lcoin. Is impossible to advance in this game wasting 0 €.
There are 2 FREE packages with sayha. ( l2 store ) Take them and use them. One of them is DAILY. So take it every day. Also you can xp, take adena and l2 coins and trade them via L2 STORE / L2 COIN STORE to sayha pots.
There is no need to complicate things This is the ncwest business model You spend real money You click the l2store button You buy random cr a p You sell it for adena Period There isn't a second way of gaining adena in the ncwest business model and even if you discover one don't worry they will delete it within two-three months eg. the heine coins-fishing rod scam Conguero said "if you find out a way to gain adena that seems too lucrative write to the support so we can erase it".
