But right now, it has a bad case of indigestion.
Can I get you to agree?
Anyway, if we want a higher gizzard AC, I'd prefer to use 10+divine+1/2 natural and just boost the natural armor bonus a bunch. Devastation vermin have a considerably higher natural armor, and even a tarrasque has +30. These should be much, much tougher.
Sure, just to move along, though I still can't say I see the reasoning other than wanting a higher AC.
Actually, a question: how are you getting the gizzard AC to be 64 or 74? It should be 10+1/2 natural + divine + 1 or 1/2 or 0 insight = 45, 55, or 65.

So something like +50 natural, +30 divine?
Insight is supposed to be Wis based, so yes, let's keep it, and it would then be +20.
I'm ok with natural of +50 or +60, either way.
