So I found the Ice cave and killed the creature in one on one combat with my lone wolf, it dropped a two handed barbarian cleaver that was supposed to be a special item. However, the stats of the weapon are worse than the ones for the regular version of the weapon, with a reduced fatigue use for skills… I sold it so I can’t send a print, sorry.
This particular weapon may not have met your expectations, but named weapons are never worse than their common counterparts. All named weapons have two effects, so in addition to lower fatigue use for skills there’ll have been another stat increase of some kind.
All of the stats where the same as the regular version of the weapon, except for armor piercing dmg, which was 33% instead of 40% of the regular one. I will try to find it in the store where I sold it to show you…
