Each of the 3 weapons for each clan breaks down similarly. The first is the high damage weapon. This one has the highest damage of all the weapons. The second is the defensive based weapon. It has a skill that greatly boosts their defense and ability to take hits. The third is the mage based weapon. It has ranged attacks that none of the other weapons can use. All weapons also have a single hit attack, a 3 hit attack, and an area attack. They also share some common skills such as formations (party buffs), heals, and various self buffs.
There are 4 stats in the game. Strength, vitality, intelligence, and dexterity. Strength gives damage and accuracy. Vitality gives hp and dodge. Intelligence gives mp and damage. Dexterity gives dodge and defense. Unlike other games, dodge works AGAINST you in this game. Defense is the much better choice making dexterity useless. When you dodge, you will cancel your current attack and take the hit and take 0 damage. This will cancel you out of your current attack and make you unable to attack for a second. Enemies don't seem to suffer from this so it makes it very annoying. To avoid all this, players focus on boosting attack and hp rather than bothering with defense at all. As a result, many players just focus on boosting strength and vitality ignoring dexterity and intelligence as much as possible. Spamming potions is possible so maximum hp is more important than anything else. The high level potions restore percentages rather than fixed amounts.
Learning skills require skill points. As long as you have a skill point, you can learn a new skill. As long as you have the proper weapon equipped, you can use the skill. Some skills such as heals have no specific weapon requirement. All of the starter skills can be learned from the correct NPC in town. However, starting at level 30(Twelve Sky2 Gold), new skills have to be learned through scrolls that are dropped from rare enemies. These scrolls just require you to have 1 skill point and use the item. Use the item and you will learn the skill. Each skill also has a different skill cap. Each skill point will increase the power and mp cost of the skill. The mp cost can go up to extremely high amounts early on. You also get more skill points per level at higher levels. At level 1 you only get 1 per level, but at level 20 you get 2 per level. Unfortunately the ability to spam potions makes healing and mp healing absolutely useless.
