Where was this when I was making the rootwalker? Great simple tool that makes monster creation a few steps easier. Now you can simply focus on the powers you want your creature to have and modify to taste.
What goes in hand with this is Asmor’s sweet MonsterMaker. The best part is that if formats it in the monster block style cleanly and easily for you. I’ve already modified the Rootwalker’s entry to reflect this, so check it out if you want to see the end results of the utility.
