You'll note the OP's DM did skip this part, which is too bad. Doing that does make it unbalanced.
The Animated enhancement costs a +2. That means, generally, that there are much cheaper ways to get AC up until level 14 or so. And after that....so what?
The primary issue I have is that ya get the free hand...exta attacks or more damage with TWF or two handed weapons, respectively. If it also took up an arm to use then no problem; though that would also negate the reason for it. So ti si not the act that the shiled is animaed; its what you can do now that it is that is the issue.
The reason this is an issue is +2 ; +2! just a mere +2! I get this for 4,000 GP! If it was +5 - no issue from my end; I still think it is overpowered but 25k versus 4k. At 4k I an buy he thing easily by 5th level!
