headhunter ??

I know that to get headhunter belt I have to use orb of chance on leather belt while I'm in nemesis map . Does it matter what tier map it is ? and does it matter what level leather belt is ?

also if I'm using Ancient orbs on unique belts to get Headhunter should I do it on just one belt or try different ones ?

Recently, the minimum level requirement for Orb of Chance is no longer needed. Any ILvl Leather Belt will work, provided you are in a Nemesis map (not an Antagonist's Map - a Nemesis map)

Also yes, Ancient Orbs can be used in a similiar fashion and is considered a quicker way to get your Headhunter, if you can withstand the price of those Orbs, and if you are in a Nemesis Map. Any non-corrupted Unique Leather Belt will work

what do you mean by not Antagonist's Map - a Nemesis map ?

Antagonist is the nemesis map mod that can roll:

"Rare Monsters each have a Nemesis Mod
(20-30)% more Rare Monsters"

Doesn't count. Has to be an actual Nemesis map from Zana mod (costs 4c at map device).
