I just threw an electrical attack on a statue that had the armor card "Ancient Statue". It should have reduced all electrical damage, but it only reduced it by 2.
Yeah, I believed there's a mismatch between what the armor card says it's immune to and what the actual code says - I think Kalin checked that. It's been reported before, but a good reminder it's still not fixed. (http://forums.cardhunter.com/threads/bug-ancient-statue.5649/)
