development of skill +15 and more

[staryman2]

How to make +15 and more 1 skill if you can't develop it divine blessing stone?

[Alkaris]

You need to get equipment evoution set bonus.

[staryman2]

must + 6lv star combo on +15?

[Alkaris]

no, 6 lvl gives only +2 to skill lvl and thats +12. Its either 9 or 10 star lvl combo.

I understand. Thank you
