I'm sure most of the gear has randomly specifications!
I found skillpoints on gear like +1 to Wisdom (Rothman's bow + a on a Ring) and +2 to Wisdom (Amulet of the North), +1 to 2-handed weapon expertise (Arben's sword), +1 to Ranger Strength (David's Gauntlets), +2 to Single-handed expertise (Brideblade, Seth's sword), +1 to Confusion on an Axe from one of the guys before I go in the Maxos Temple (Marius, etc) ...
Also the weapon of Talana ("Witch's Slayerbane of the Mage Priest") have a skillpoint, but don't remember what kind of skill...
Rabbit's Power Belt of Aleroth from "Louis' Stash" (level 5 belt) have a +1 to Evade.
The "(Magical)Striking Plain Pewter Band of the Warrior Gods" I found have a +1 to Magic Missile +
the "Fearsome Oriental Gold Earrings of Aleroth" : +1 to Fear ...
And Jagon's Amulet +1 to Lockpick : I used this early in the game for an extra point for a while to open chests and later on I give the necklage away to solve the quest

That's all I found for now in my second playround, now at level 16, just come to Sentinel Island and do almost all quests in Brocken Valley....
