I have not had a chance to read it yet, but I am excited to look through it. My group fought (and narrowly defeated) the Juvenile Horned Dragon at the end of the Beginning Box on Sunday. I am hoping there is more dragon stuff I can throw at them because they had a blast fighting it.
I hope it can improve the primal dragons options for wildshape. felt it got kinda nerfed with the redo of dragonshape whereas before it had access to most elemental type of breath weaon.
