Hello, guys, glad to see you at Thepowerlevel ! I found some skills information in 12Sky2, here we go 

1. Skill Points - With levels Skill Points are gained , and it can be applied towards skills. Skills are learned through Weapon Trainers in the Faction home towns at low levels. Weapon Trainers are located near the Faction Elder.

2. Using SKills - It can be assigned to the Shortcut Bar when a skill is learned. Players can choose the default hotkeys 1-10 or switch to F1-F10. There are 3 Bars, toggled with "X" (forward) and "Z". Also the "Q", "W", "E", "R" can be shortcuts.

Press "S" to open the character Skill window
Click and Drag the skill to the Shortcut Bar
Press the corresponding hotkey to use/activate

3. Leveling Skills in Twelvesky2 - Skill points can be applied directly to the skill's level without needing a Weapon Trainer once you have learned a skill.

Press the "+" to increase a skill's level.

- Once their level is altered Skills must be re-assigned to the Shortcut Bar.
- When hunting monsters leveling down a skill can help preserve Chi.
