This page needs to be cleaned up

Needs to follow outline for a skills page.

It makes most of the items perform better, war items, offensive items, and self-use items.

The numbers associated with this are:

Skill Level 1-5:2% Skill Level 6-10:4% Skill Level 10-15:6% Skill Level 16-20:8%

Also, an increased chance for items to penetrate barriers. (exact amount unknown)

Some of the more powerful items (like Ash of Invisibility or Magical Compass) are less or not boosted at all.
It improves Locate Artifact results (No longer does on solo)
It does not improve effects of Unique Items (tested with Crystal of Tear)
It is not clear if the skill improves item generation. (It seems likely, however)
It has odd effects with some items, like causing Satchel of Mist to increase your accuracy instead of decrease it. forum post

History

This skill replaced the Barrier Proficiency as the skill in December-January 2006-2007.
Barrier Proficiency at that time became a skill, and its workings were also changed.
The replacement probably had something to do with the spell-level effect on barriers being removed between original skill design (late 2004) and reintroduction of skills (halfway 2006).
