Talk:Void Staff/@comment-25122281-20151115205205

Is this a situational item when enemies have a lot of MR, or is it mandatory in every match on AP carries?

According to the graph, even when they have 40 MR it increases your damage by 10%, which is quite big - e.g. with 500 AP Void Staff effectively gives you 120 AP in this scenario and increases your base damages on top of that.

So isn't it like the old Last Whisper - just a must build in every match, regardless of the enemy build?
