I have 5 items with Magnus' and 4 with Torug's. 2 of the Torug's are swords that I dual wield for maximum spell damage. I've always gotten credit for both - i.e. I got credit for having 4 items in Torug's Pact.
I just noticed that I'm now only getting credit for 1. If I de-equip the off-hand sword, it stays at 3 of Torug's. Still getting the increased damage.
Have they removed the ability for the off-hand weapon to count toward set bonuses? Anyone else seeing this, or are you still seeing both dual wield weapons count toward your set bonus?
