Talk:Black Cleaver/@comment-26107214-20150521021131

Just a simple question. DOES the new Black cleaver and Last Whisper stack? i mean the Black Cleaver passive says that it reduces the enemyy armor by 5% per stack whch stack up to 6 times(confirmed to proc every hit on ashe's q btw) and the Last Whisper grants 35% armor penetration. so does this two stack?
