So did we ever figure out if arcane scaling on a weapon like the Kirkhammer or Ludwigs sword actually increases damage? I'd like to know before dumping a bunch of points into arcane.
Oh, this isnt common knowledge?
Okay, so when it says A arcane scaling, you still have to waste a gem to switch the scaling type over to arcane. The issue with this is- say you had +100 from str, +100 from skill, and +150 from arcane.
Arcane being active via a gem (from what I've seen) makes the damage type arcane- so you lose both of the other two, making it a worse choice. My advice is still just scale off str/skill, then apply a lovely arcane buff via your 15 arcane points that I've been nagging people to get so they can use the amazing buff.
