Kayle Armor Pen Bug
I was playing a custom game on summoners rift using the aether wing skin for Kayle, but anyhow I was just messing around with attack damage Kayle and built a Black Cleaver and a Last Whisper and I noticed that instead of my physical (not magic) damage going up on each strike, since I would be lowering their armor and magic resistance with each strike, it actually went down. I'm not sure if this is a bug with the Kayle passive and the black cleaver or if its intentional. Thanks for looking into this.
