Why you need Void staff as your second main item as an AP mid

Someone did that math once, but I can't find it (might have been on a
stream). With targets around 70-80 or
more mr, purchasing void staff will do
more damage than deathcap (all while
being ~1000g cheaper). Having 70+ mr
is nearly a certainty with the addition
of bulwark. If you aren't fitting a void
staff into your builds somewhere, you
need to re-evaluate them.

EDIT FOR PROOF : I just did the math
out for a level 11 Syndra (maxing
R>Q>W>E), who has one of the
highest burst ratios in the game. I
even padded it in her favor by giving
her 5 balls out for her ult (to give her
higher ratios). Here are the
calculations:
Full burst combo: 230(.6) + 160(.7) +
70(.4) + 675(1)
Simpler Form: 1135(2.7)
100AP from runes/masteries/dorans
or whatever
Deathcap ((100 + 120) * 1.25 = 275
AP)
Voidstaff (170AP) + 35% pen
DC Pre Resistances : 1135 + (2.7 * 275)
= 1887.5
VS Pre Resistances : 1135 + (2.7 * 170)
= 1594
DC Damage With 80MR : 1887.5 *
(100/(100 + 80)) = 1048.61
VS Reduction with 80MR: 80 * .65 = 52
VS Damage with 80MR: 1594 * (100/
(100 + 52)) = 1048.68

Voidstaff wins by a fraction, while
being 1000g cheaper. It also scales
better per additional AP than
deathcap (35% pen vs 25% addition
ap), while also scaling against
resistances (if the enemies buy more
mr). I left out pen from runes and
masteries, though if people want I
can do it with those too.

TL;DR : EVEN ON HIGH SCALING AP CHAMPIONS, VOID STAFF DOES MORE DAMAGE, SCALES BETTER, AND IS SIGNIFICANTLY CHEAPER THAN DEATHCAP.


So basically, AP mid build = boots+big item->void staff

I like boots+deathcap+void staff, as every bit of AP after that core gets amplified by Void and Deathcap so the gold efficiency is amazing.

Or you can get a haunting guise for even less money, and not have a wasted slot for enemies that haven't built MR yet.

I usually get it second anyway. I like the (false) sense of security it gives me, particularly with Lux...
