Talking to a respective subclass Teacher in the capital of one's Empire
Reset Skills for You Character below Level 30: The following Tera Gold guide will explain the procedure of resetting your character skills and re-utilizing newly available skill points below level 30 of Metin2, please have a read.
The easiest way to reset skills is to talk to Old Lady in Empire's capital and select option "Return Skills".
It will cost certain amount of yang (the exact amount depends on the character's level, but around level 20 one has to pay approximately 60k yang for the service).
After selecting this option, all of the character's skills will be reset, all skill points will be returned (number of skill points available is equal to character's level minus one point), and character's subclass will be reset to the undefined state.
Talking to a respective subclass Teacher in the capital of one's Empire will allow one to choose character's subclass again and start putting skill points into available skills.
This procedure can be repeated infinite amount of times (each time for yang payment), as long as the character's level is below 30. Thanks for reading and welcome next time!
