Sox drop rates

Hello,
I Changed the rarity to 3 in refobjcommon but the sox drop rate is very high
also if i make it 2 no sox drop.

i changed the rate in _RefDropClassSel_RareEquip to low rates no thing happens still the same high rates

also if i changed the normal rates in _RefDropClassSel_Equip to high rates so high sox and if low rates = low sox and low normal :D

i need to change normal to high rates and sox to low rates how can this happen ?
