Hey,
I'm playing the DKS (Xbox) and have another kind of
Amulet of the North !
By me this amulet has:
+ 2 to Wisdom
AND
+ 1 to hide in Shadows !!
So the + 1 to Wisdom is a
random bonus skill
The other boost on this Amulet I think are + 5 to Magic Damage and + 2 (or 3) to Ind. Will
(Plus have 3 empty Enchantment slots)
