If it fails all of the above, it is low quality.

It first goes through these steps for unique items, then rares, then sets (yes, not the other way round), then magic items, then superior items, then normal items. Rare: if MF > 10 then EMF = MF*250/(MF+600) else EMF = MF Set: if MF > 10 then EMF = MF*250/(MF+500) else EMF = MF Multiplication for extra precision: chance = chance*128Д®MF is counted in: chance = chance*100/(100+EMF)Д¬omparison to itemtypes Min: if (chance 10 then EMF = MF*250/(MF+250) else EMF = MF

The quality of item drops is based on several factors: the stats in itemratio.txt, the treasure class (bosses drop better than regular monsters), and the item level compared to monster level.Д«ase chance: chance = itemratio - ( mlvl- ilvl)/div
