Is Void Staff always effective, or it's meant to be situational?
For almost every ap mid I used (spell-based, like Annie) I bought the same thing: boots, rabadon and void staff.
There're certain moments where I start asking myself... Would it be more benefical in all situations to get even more AP, or is void staff still the best option even if almost no one buys magic resistance?
However I always feel safer to get void after rabadon, as it guarantees there's less chance of survival for them against my champ's spells.
Best Answer
You want to get void staff if they are building a lot of Magic Resist. I usually build it on most midlane champs due to the fact it helps all your spells do more damage. It shouldn't be built early because there are many more viable options early but in the late game it becomes extremely viable. Nidalee would be one you would want to get it right after rabbadons deathcap because it makes your spears hit even harder. You rarely see an adr without Last whisperer for the same reason.

Void Staff is a little different - it ignores 35% of the total magic resist. So using the two sample champions from before, no matter what their ratio of base vs. bonus magic resist is, they would both have their 100 total magic resistance changed to 65.How gold efficient is void staff?

Answer 2
that would mostly depend whether your having a hard time against enemy champions and you're skill set. i'll focus on the champion that you mentioned here, which is annie. void staff is generally a good item especially you have rabadon before you get void staff, although yes it would be better if you get abysmal IF no one is really getting m.res in the opposing team. also annie is a burst hero that must lay down everything she's got in the first few seconds of a team fight.
