I have a theoretical build that should rival that of the Lethality build people use.

The shift from magic penetration to this ramping damage boost that is actually lower than the previous penetration boost seems terrible. However, there is one notable benefit that sets it above magic penetration, it scales with magic penetration.

Now, this damage boost is actually a general damage boost, so it could boost. However, this is obviously an item, so it would be better to think in terms of magic penetration.

Now what I mean by that it scales with magic penetration is that since Madness is its own damage boost, it doesn't add to the magic penetration multiplier, it multiplies the magic penetration multiplier.

For example, if you had 50 magic penetration, this would multiply the 1.5x boost by 1.1x. This means you end up with something that feels a bit stronger than a 1.65x boost. That is 5% more damage than if you just had 60 magic penetration.

Now what I find incredibly interesting from this point on is that there is also another item that has it's own multiplier:. So not only does the 1.1x boost from full Madness scale with magic penetration, it also scales with. This is where things get crazy.

With, , and someone with , the penetration/reduction gains end up with 1.63x. This multiplied with the 1.15x boost from, it ends up being 1.8745x. Finally, to put the icing on the cake, throw in full Madness from to multiply this by 1.1x and you end up with a massive 2.06195x.

That means everything combined would increase magic damage by an enormous:

{as|+106.195% magic damage}}

Now wouldn't that be fun? Best part is, two of these items, you don't even need to get. So, while alone, looks like garbage. When combined with something massive, it becomes an absolute monstrosity.

I suggest trying this with the same idea that you would use Lethality for. If your champ has a lot of base that you want to enhance alongside with your {as|AP}} scalings.

Notable champions include:

I highly recommend finding other champions willing to use and. Preferably, both.
