Welcome to TalonRO.
Here are some links to help you out.
Class Discussion. People here have made guides on good ways to develop strong builds and where to level. https://forum.talonro.com/forum/13-class-discussion/
In case you are starting out, Archer class is pretty easy to pick up and you can do some serious damage early on.
This link below should be more than enough to help you work towards a goal in buying equipment and what to level your stats up.
When ingame you can always ask for help, people are pretty friendly and can give you some good information on what to do and what not to do.
Best of luck on the server and I hope you enjoy your time here!
