There is 1 thing that i wanna suggest.
Socketing Rod can only bought with balens atm, some people will not recharge for this game
My suggestion is you guys can ....
1. make Socketing Rod for lvl 20-29, lvl 30-39, lvl 40-49 etc
2. can get socketing Rod in other ways, for example, Mult dungeon ( of coz not everytime but a chance )
3. if making socketing rod for different lvl, you can also upgrade from the lower lvl rod, for example, 2 lvl 20-29 combine a lvl 30-39 one
