Running queries without understanding what they do is typical for every retarded server out there.If you want to edit sox drops = _RefDropClassSel_RareEquip.
Each sox degree has 3 columns, ProbGroup1 = degree 1 SOS / ProbGroup2 = degree 1 SOM / ProbGroup3 = degree 1 SUN and so on, I think you can figure out the rest.
Rows MonLevel = monster level range.
As for NPCs, there are 4 tables you have: RefPackageItem/RefShopGoods/RefPricePolicyOfItem/RefScrapOfPackageItem.
