Stat Guide
If you kill Bosses or midhigh Lv. monsters they drop Lumber.
With Lumber you can buy Stats after Lv.5, the Teleport is on Spawn area at the top right corner.
Your main stat costs 2/20/200 Lumber and your off Stats 5/50/500
After you get 10k Total Stats, your shop will change, now the stats cost 5/50/500 and 10/100/1000
After you get 120k Total Stats, your shop will change, now the stats cost 8/80/800 and 16/160/1600
After tiering up, you have 1/2 of your total stats as Mainstat.
