Skills
There are 17 skills in FOnline: Reloaded. At the beginning of the game you have to choose your 3 tagged skills. The skills you want to pick depends on who you want to become (Warrior, Crafter, Doctor, Wanderer, e.t.c.). The percentage of the skill shows how good you are at that skill. Each time you level up, you will gain some skill points. You can spend these points to increase your skills. Note that fewer skill points are required to increase the three skills you tagged when you registered the character. Note that weapon skill is a major factor determining your Chance to hit.
Skills Table
This lists all of the skills, and each ones' limit. The Tag column is Yes/No, and is only a suggestion whether you should Tag it or not. This is based on how high a skill goes. In most cases, it's considered a mistake to Tag a skill that has a low limit, and most players only tag skills with higher limits, though exceptions are always at the player's discretion.
In the case of combat skills, Related Perks are many, and some are specific to certain weapons rather than the all of the weapons in that class. See next section for popular choices.
