Attacking
You can attack a hostile target by Right-Clicking on it.

Selecting Aggressive Monsters
A target with a red selection circle will attack if you get too close.

Leveling Up
Every time your character gains a level, you get an increase in stats. Every even numbered level, your character gains access to new skills, which can be learned at your class trainer. At level 10, your character begins gaining a talent point per level, which can be used to learn new talents, by hitting the "n" key.

At Level 3 or 4
You can go to your trainer in your starting area and learn a new skill. Your trainer is in the area near to where you started, but you might have to search a little. You can ask other players for help if you cannot find them. The class trainer will show your class name under their name. For example, <Paladin Trainer>.

Reputation Changes
