I think the main problem is that we can have 30 armor class w/o buffs and 15 saving throws with advantage w/o buffs. I can achieve around 40-46 armor class with and every one have disadvantage aganst me with 50% dmg reduction.
30 ac "without buffs"? not sure i believe it. at what stage of the game?
End game I have got shadow heart to 27, I don't know how to get 30 but I absolutely believe it's possible.
