Hey,

The only thing you should spend your Sun Coins is:

- Advance Refines
- Epic Refines
- Discounted Bond Scrolls

As it seems u are a beginner. I would advice u to go only for Advance Refines.
Later on, if u need some assist links going for Discounted Bond Scrolls is also an option.
And when u will have Position 1 max Advance Refines, I would advise u to go for Epic Refines.

Thank you~
