best place to hunt preserved heads since they have a qlvl of 4, does that mean i need to be killing stuff of at least level 4? also do low quality versions have a lower qlvl? or does the TC these drop out of mean i have to hunt something a bit higher level. Specifically I'm hunting for a preserved head with +3 RS and +3SM. Now also, the staffmod part of generation says it has a 20% chance to pick a skill at the next tier up, that being a level 6 skill if the ilvl is 1-11. If though I pick up an item that is ilvl 4-5, does that mean it cannot have a level 6 skill on it?
