Confused by AA? Xalmat brings us a wonderful Alternate Advancements guide.

Alternate Advancements, or AAs for short, are a means of further enhancing your character. They can give your character powerful new skills and enhance existing skills. In addition to levels, they are a means of measuring how powerful your character is relative to other characters of the same class. 

We are pleased to bring you this Alternate Advancement guide, submitted by Xalmat, which explains the basics of the AA system.
