Zao recently went over a huge overhaul to convert from the Master Summoner archetype, which we deemed too powerful. Some GM allowances were made, but it looks like I have some mistakes to correct too. I've rolled exceptionally well on HP for Zao and that is accurate, due largely to rolls of 1 & 2 not counting I got an 8 on a lot of those. Zao wears a magic item that boosts his Perception by +5, so your math is dead on. Will have to go over and fix the eidolons, I think most of your points were valid. I never read anything about the bleed evolution having to apply to a natural or edged attack. The evolution said choose an attack. Will double check and correct the other items when I have time over the next few nights and offer corrections and explainations as needed. And don't worry about the public forum Gunther. If there are issues, which obviously there are, I'd like to get them fixed.
