Talk:Rabadon's Deathcap/@comment-160.5.232.116-20120214164337

I know this may seem like a stupidly obvious question... but I have always been a little unsure about it. Does Rabadon's Deathcap +30% passive affect any items after it was bought?

For example I buy a RoA and Rabadon's which would give me about 260 AP, I think. Then I buy a Lich Bane. Will the Rabadon's effect only work with those items I have before I get Rabadon's or will anything after that will also work?
