AP/Critical Items

I think he is not talking about a critical cast item (I think it is the proper term for an spell that critically strikes).

But about an item that grants both Critical Strike Chance and AP It could be perfect on Nidalee, Diana, Akali and Corki, if it added extra damage intro the crit from AP when it proc on the critical hit. But It would work on very specific cases, still I think the idea is good, and could even work for TF.

Also I've designed an item for AP bruisers. can you see my custom item? I've made an icon for it! http://boards.na.leagueoflegends.com/en/c/skin-champion-concepts/buOIBEzA-the-phoenixs-talon-icon-made-by-me-3
