How do I fix the skill?

[eorbsdld]

Hi, I'm Private Server Manager.
I want to modify the skill at will.
For example, to increase the damage of the skill, or to change the job of learning a skill.
Please let me know.
Please do me a favor...
Thank you.

I knew I could change the description of the skill while modifying the libconfig.dat file, but it failed.
Help me please...!!
