You can try to farm Frog legs and Frog tounges here:
You just run ch1>2>3>4>5>6 all over again clear spot and move on, you can drop like 25 legs and 30 tounges in hour. Keep in mind that they're not sellling very well on market.
You think someone will believe that members of your guild used bugs and you were sitting with them daily and no one told you about it, when whole guild knew they won't be punished? You think someone was born yesterday?
I just want to say I got INSTANT perma banned because there was a suspicion that I used some kind of bug ONCE (0 yang profit). I had to fight whole day to get my account back and here is Thuggy who was bugging bosses for months and got his eq done because of bug. There is no doubt he should be...
So i belive you just kill metin to slow to unlock full potential. What lvl are you? Maybe you can go back for weaker metins if not you can try farm some materials to improve your eq a little to kill metins faster.
