Keep in mind that traditionally two points of AP are valued at the same price as one point of AD, and Vorpal Spikes have a 30% AP scaling. That means that for every ten points of AP you buy you will do three more magic damage on each auto, at the same price as buying 5 more AD for 5 more physical damage per auto. So for every two more points of damage per auto you gain by buying AD, you lose 7 points of damage per W per target and 10 points of damage per Q per target, along with 7 points of true damage on R. In addition to that, if the vorpal spikes manage to hit two champions, your 10 AP will add six points of total damage, as opposed to the five points of damage that 5 AD would add.

If we assume that one point of true damage is worth two points of physical damage, one point of magical damage is worth one point of physical damage, two points of AP are worth one point of AD, and we ignore Sheen/Rabbadon's/Criticals/ect, for AD to be worth as much as AP..

Each target that gets hit by Q must be offset by 5 auto attacks

Each target that gets hit by W must be offset by 3.5 auto attacks

Each target hit by E after the first must be offset by .67 auto attacks

Each use of R must be offset by 7 auto attacks.
