So, I look at 
, and i just see a lich bane with 40% of its AP scaling removed, and a tiny AoE that does very little to nothing, and a mana sustain effect that's nice for the jungle, and doesn't exist in lane. How the hell does this break AP 
in any way that 
doesn't do better? Can anyone explain this to me, because I just don't get it.
Sightless666 votesThere are a few things this does for Ezreal. First, it converts his Q damage into magic damage. That allows it to work against his opponents MR (tends to be lower than armor), and allows it to benefit from his magic penetration. Those are both major increases to his potential damage. Lichbane doesn't do that. You actually end up with more damage on a runeglaive Q than a Lichbane Q just because of this one trait. Seriously, it hurts more than Lichbane does just because you can use your magic penetration.
However, that's not the only damage benefit. Runeglaive allows your autoattacks to proc spell effects, which for Ezreal means that his Q can proc spell effects. This makes Luden's Echo wonderful for AP Ezreal. Normally, Ezreal's Q won't proc Luden's, but it will if you have Runeglaive. That's a lot of extra poke than any other kind of Ezreal just doesn't have access too.
Additionally, the mana sustain does exist in lane for AP Ezreal. Go mid, Q the chickens over the wall, get mana back. You can stay at around 25% mana forever even you farm entirely with Q. No one can deny you any farm, and you turn into an annoying spamming poker that is very, very hard to bully, pressure, or kill.
This is also where the AoE comes in. Traditionally, one of Ezreal's weaknesses is that he can easily be pushed in. He has no form of waveclear outside his ultimate, so shoving it in and forcing him to farm under tower is a great way to lower his farm and make him generally miserable. With Runeglaive, he has enough pushing power on his Q to prevent attempts to force him in.
Celosar1 votesEzreal's Q has always proc'd any spell blade effect. It also has always proc'd Luden's.
Nameless Voice4 votesNo, it hasn't.
Celosar1 votesI haven't played blue Ezreal in months and I'm pretty fucking sure his Q proc'd Iceborn every time I cast it. By pretty sure I mean it did. Maybe this was a buff at some point but it sure as hell wasn't recent. So the addition of this item literally did jack and shit for his Q as far as proc'ing on hit effects with the exception of making it magic damage, which I'm not saying is irrelevant.
SaltyKracka1 votesYou're an idiot who needs to take some reading comprehension courses.
Ezreal Q procs on-hit effects, such as Sheen buffs from the likes of Iceborn Gauntlet.
Runeglaive (currently) allows his Q to proc spell effects, such as Luden's Echo and Rylai's.
Celosar1 votesI honestly didn't even know there was a difference, so count me educated.
Also, you people are a bunch of assholes and should possibly just say that instead of your bullshit like, "No, it hasn't", but then again these are the forums and people are just dickheads so I guess it's w/e.
Nameless Voice2 votesSo you're okay with the guy above outright insulting you, but take offence to me flatly stating that Ezreal's Q has never proced Luden's before?
Oookay.
Celosar1 votesNo I think you are both equally pricks.
Nameless Voice2 votesThis. Also, having Smite means he can get Ranger's Trailblazer and use Blasting Smite to clear waves, further helping him against opponents who push.
DorkunedAuras1 votesThank you very much for the in-depth insight on how this works. I believe that Runeglaive proccing luden's is a bug, and is getting patched, but otherwise it's actually getting buffed next patch.
I was no aware of the complete conversion of the damage to magic, and that seems like something that should either be on Lich, or neither.
I never considered just Qing the raptors, though you have to keep track of when your jungler has mown through there, and Runeglaive mid doesn't really synergize too well with a farming jungler like yi, udyr, shyv, etc.
I guess I underestimated the value of the AoE as well, though I still don't think it does too much. Some is more than none though.
Thanks again for clearing this up, should probably get a bit of a nerf to lane, maybe making it so it AoEs the rest of the monster camp automatically, instead of just AoEing stuff?
Galewings1 votesRuneglaive is a lot cheaper than Lichbane and it also is bugged at the moment which allows it to proc ludens (This is not intended to work and will be fixed next patch). Essentially it allows AP Ez to reach his power spike a lot earlier and makes his Q have a 110% ap scaling with the ludens bug.
Not to mention it can also give ez more waveclear and sustain when he brings in or some better duel potential and true damage if he gets (Which I personally don't like since you should never even be in range to use that smite anyway).
khorney1 votesit allows people who have spellblade procs ie ez nasus rengar quinn vayne etcetc to have it do magic damage instead of physical damage
xJLx MCHammer1 votesIt gives him wave clear, sustain, and procs ludens
Stillshade1 votesthe thing is. ap ezreal has always been strong, but aside from his ult he never had any waveclear, with runeglaive not only does it give him aoe waveclear it also lets his autos in between qs do extra dmg as well.
jDVL20eCYs1 votesrunglaive in it self is rather weak why its getting buffed next patch.

One of the problems is the converting damage in to AP. An ap jungler already does AP damage so i dont understand the reasoning behind it.
Meep Man1 votesIt gave AP Ezreal great wave clear besides his ultimate.
khorney1 votesHonestly it. Procing ludens is minute it's more for the aoe and turns your spellblade proc into magic damage .

SaltyKracka1 votesPersonally, I hate it because not only has it allowed AP Ezreal back in, but because it's also a buff to Jungle Nidalee.
And every time somebody plays jungle Nid, I want to punt a puppy.
