The PHG groups have two druids, a Shapeshifter and an Elemental druid. The Elemental druid is probably the second most powerful and balanced character build in the game. An Elemental druid will use the Hurricane skill along with Tornado to do massive amounts of cold and physical damage.
There are several skills in the elemental tab which are synergistic with each other. In this build we pump each of the key synergies to the max of 20. This will increase when skill points from equipment are added -- yielding even higher damage.
No, none, zero, zip, zilch points are assigned in the shapeshifting tab. Do not use points for "in the beginning." When creating a build stick to the build. If you think assigning a point to shape shifting is a solution for something, go back to the blackboard and look for a different solution -- one that does not waste skill points.
In this build the "extra" skill points are put into Bear. Some folks like to put the skill points into Oak Sage to increase its survivability. That is a question of preference. The bear can be a very productive partner in your gaming. So perhaps in one realm favor the bear and when building an elemental druid in a different realm favor the Oak Sage.
