Hey guys, I was hoping to get your opinion on using Greater Quintessence of Magic Penetration (1-3) on mid laners, specifically a nuker like Lux rather than a DPS caster like Ryze. I've had and heard mixed opinion about this quint and I'm not quite sure what my stance on it should be. Right now I don't use them (mostly because I have other quints to buy) and I generally think AP quints are better.

Right now I'd prefer if we'd keep this comparison between Greater Quintessence of Magic Penetration and Greater Quintessence of Ability Power. Math is nice as long as it's clear and to the point.

It would probably be a good idea to compare the effectiveness of the quints against a typical mid laner running 21/0/9 with base MR of 30. Might want to run the comparison twice, one with and one without Greater Glyph of Magic Resist. I realize that might reduce the usefulness of flat Mpen.

Thank you in advance for your help!

EDIT: If you need specific scalings, just use Lux's. She's the main point of the thread. Also assume that you're using Greater Mark of Magic Penetration, Sorcerer's Shoes and eventually building Void Staff.
Thanks to Nyoike for the sig!

I think it'd work well on casters with high base damage.

If a mid does not scale too well with AP and/or you are not buying a Void Staff you could opt for MPen Quints, yeah. Otherwise I'd stay away from them.

I think the best Annie guide ever features magicpen quints with graphs.

But PsiGuard.

Why would you assume you're using Mpen reds?

We all know those are bad ;)

That was the best argument. Ever.

I know Duff, I'll get them eventually. I think I'm going to get MR quints first though.

Any mathcrafters out there? I like me some math.

I've done the math on mag pen runes in general, and getting any penetration, whether it be physical or magical, will give you an increase in damage corresponding to the amount of pen you're getting.

I.E. Greater Quintessence of Magic Penetration will give you a net increase of 1.89% overall. If your AP scaling will give you more than an increase of 1.89%, that's assuming all of your spells hit of course, then it's better to be taking the AP quints.

Most people take the AP quints, myself included, because they probably can't be arsed to do the math on which is better in any given situation.


Thank you to jhoijhoi for the sig, and all the dividers in the guide.

But I want someone to be arsed to. :S

EDIT: Btw my client shows mpen quints to be worth 2.18, not 1.89. Is the database outdated because of the change to mid laner runes a few patches ago?

I'm not entirely sure because the wiki is still showing what we have.

I would change based on the client but I'm planning on doing this important thing called "sleep" real soon.
