+x to an evil force on vamp gaze looks like it's supposed to be "Bone Golem". Not sure what/when/by who it was added. The skill has no skilldesc.txt entry, hence an evil force. You don't actually get the skill because it's not a class skill and the item uses "skill" rather than "oskill" so it won't be applied anyway. If it is to be added, it needs a skilldesc entry and a proper skill icon entry or the game will crash when you open the skill list.
Additional bug: Thunder storm calls the skill "Static" for one of it's synergies. Should be "Static Field" so it's only got 1 synergy from Nova at the minute.
