Nightfury is a halloween item that requires considerable resources to craft, and could refer to any of the following: The container: Nightfury Skin. The three ascended armor shoulderpieces with the sinister prefix: Nightfury (light) Nightfury (medium) Nightfury (heavy) The three wardrobe skins unlocked upon usage of the container:
Ascended weapons have a bigger damage impact if I remember correctly. Yes, if you want to get the most stats than accessories > weapons > armour is the best order. Weapons also may have two infusion slots (on two handed weapons) as opposed to one, which may be a minor upside. Not on condi builds, which OP is using.
Bers, condi , ham/hamtank, some diviners pieces/ (trinkets or armor) + a special set for whatever. Power always having the upside of not needing runeswapping. Same goes for ham/druid. If you dislike ranger/thief then legendary medium loses value if you would actually play different playstyles of another weight class. 5HUpI.
