Yaulp and Yaulp II and likely Yaulp III Are off, rank 1 is giving 5 ac which it was acutally 20 ac, and Rank 2 was giving 10 ac when it should be 30 AC, and Rank 3 was only giving 15 ac when it should be 40 AC. The number of STR is fine tho.

I got a Book called Prima's Offical Strategy Guide which states the stats for Rank 1 and 2 and going in corrective order of the last 2 ranks Id assum the AC retrun for 3 would only be 10 more then the last. I know AC dont matter much on this server until you hit 800 plus, but for Pallys it is a nice boost vs the lame 5 and 10 ac (which isnt classic). I can provide a Photo of what this book has, its on page 497 and, 498...incase you have a copy of it...I use that a score when im building my no nerf server often. At least for any spells level 1 to 20.
