Well i have masterd this game. I know all there is to know about this game that is.
Here are some funn things ill teach you this fine day about ragnarok ^^.
Well lets talk classes first. my fave class is deff the assasin meaning 2 daggers and on a high ro server meaning 8 cards. /gg
My suggestion for daggers are the grimtooth. 2 of those suckas and your safe. Thell will giv you more flee than 4 phrees can handle.
My segestion of the cards is to use turtle generals that give you 20% on str. about 7 of those and a phree for those pesky snipers.
Now the key to high dmg is edowing yourself, you can eather make a 2nd acc and use a sage or you can go to gefenia04 and get some cursed waters, almost no one knows about these, and are not expecting a dark attack.
Now that you are a haxor lets learn some things to make you a Hacker.
I suggest using Winsock Packet Editor, with this the possibilities are endless, dupe, create, and the

out the server.
you can find it here >

Now if the gm starts to piss you off why not crash his server? /heh
Most privet servers are vonerable to this but some are not so dont be like "CAMADOT YOU SUCK!!!! FLAME FLAM FLAME" but all you have to do is type in special chars like so, ex. ó♠Õ
