==Runestone Scarcity==

There are seven Runestone quality levels, roughly distributed so that levels one and two are found as a character progresses through Normal, three and four are found in Nightmare, five and six in Hell, and the final seventh rank is found exclusively in [[Inferno]] (each Runestone's quality can be determined by the number of points around its edge). It's not known how common or rare Runestones will be, or whether or not all five types will be equally difficult to find. The most recent information about the subject came from a forum post by Bashiok in January 2011.<ref>[http://diablo.incgamers.com/blog/comments/runestone-info-galore/ Bashiok forum post] - Blue Tracker, January 12, 2011</ref>
