Im new to EQ and am wanting to try out warden. I would like to shapeshift but I am unsure how/where to spend my Advancement Points?
You can spend AA points in the character development / alternate advancement window, which by default is opened with the "L" key. The druid "shapeshift" ability is the first one at the very top of the "Druid" tab -- you only need a single point in that ability in order to access the shapeshift forms (more points will just give you a bit more regular stats).
