Changes

The [[Diablo III Beta]] started in September 2011, and while it ran, all of the [[skills]] underwent continued to undergo extensive iteration. Skill changes varied from changing the levels the skills are unlocked, to changes in resource cost, damage, and even function. A few skills were removed altogether, and a few new ones were added. Also, the entire skill system received an overhaul with the [[Beta Patch 13]] update in February 2012, with physical runes replaced by rune effects that automatically unlock at various levels for the different skills.<noinclude>
