Still fantastic, it spikes a bit earlier this season too at the cost of some raw mana compared to last season. I detail in the guide why I don't like Presence of Mind on AP Kog, namely that the overall mana regen it offers is generally less than Manaflow Band, and Manaflow already doesn't give enough mana for me to want.

No reason you can't do both. Kog is mana hungry enough to make it a reasonable choice, especially with the across-the-board nerfing of mana on items. Admittedly a precision + sorcery rune distribution is completely at odds with what's stated in the guide, but that doesn't make it a bad idea. One option I don't see mentioned is phase rush, which could be great for kog since he has to stay at an appropriate distance, and it would generally help with his ability to kite and harass safely both in and out of lane. Then you take manaflow band, take transcendence to reduce the cd on your e, (it partially refunds your cds for a kill or assist after level 11 now, which is great when you consider how much power and utility his e provides) and scorch because it's the least terrible rune in that row. (who the hell takes waterwalking XD ) Then in the precision tree you take presence of mind for mana, and coup de grace because it synergizes with your ult by amplifying execution damage. The best part is that you're not giving up any damage by doing this because none of the runes listed by the guide do much for damage. (not a criticism, just pointing this out. As a side note, the clarity spell doesn't exist anymore outside aram but is still listed on the unsealed spellbook spoiler)

Or you could just swap out the resolve tree for the precision tree because adding a negligible amount of armor and HP doesn't actually help kog with being long range artillery, or even a mid-range mage. May as well have more mana and an execution damage amp instead.

What do you think about RoA? I do it sometimes, vs burst comps

Not much a fan of it. It slows down an already-slow build and raw AP isn't even a great stat for AP Kog. Would rather continue building up to the more magic-pen oriented choices instead.

Kog'maw is disgusting, although he really is an interesting champion
I didn't read your guide thoroughly because I am not planning to play this champion whatsoever, but again, I know your other guides as I have commented, so I know that this will be useful for my friends and probably will share it with them :>

Yo, AP Kogmaw is getting a buff next patch! (10.13)

Pretty unexpected, but kind of nice! It doesn't change the build order but it does make AP Kog's late game even more powerful which is scary to think about.

I think you should update your guide a little bit because he scales harder with AP now, 70% on his Q, and 35% on his R base damage boosted to 70% if the enemy is below 40%. I think it's possible to build pure AP and kill the backline with just 4 Rs.

hiii aqua dragon, you might want to update for clarification that killing Aqua Dragons no longer gives mana regen (Flat Mana Isn't Great; Mana Regen Is section)

Oh thanks! I thought I remembered to change it, but it seems not. I'll fix it right now!

It's been quite a long time since I posted something here. I'm surprised that after all this time I have never seen you write anything about Elixir of Sorcery anywhere in this guide. As the most gold efficient item in the game for taking down towers, I'm surprised it's MIA.

Where would you put the item & when would you consider buying it?

Sorry it's taken me so long to get back to you!

I tend to just exclude elixirs from my guides since they're kind of self-assumed. You buy them when you either a) have nothing else you can buy or b) desperately need to win one pivotal teamfight to turn around a losing game, like a baron fight.

That's true for all champions, and remains true for AP Kog. I tend to build the elixir shortly after getting Void Staff, and before I start saving up the massive gold required for Archangel or Morellos.

Hello! thanks so much again for updating the page. my experience with Kog'mid has been great so far still.
I had a question however since the Manaflowband has changed to have more...Tear of the Goddess-like stats. It increases your max mana after hitting your enemy.
Would you consider taking this over the Ultimate Hat now? :)

Aqua Dragon (42) | April 6, 2018 6:59am
Howdy! I just attached a link with my current experiments to the top of the guide, so check that out!

I don't think Manaflow is that great on AP Kog. That being said, it is *still* better than Gathering Storm and Ultimate Hat, since CDR and AP are really low priorities now, so that means Manaflow is still okay.

But because Manaflow isn't that awesome, I'm testing out trees that don't necessarily use Sorcery that much.

Oh! thanks for the subreddit. I subscribed to it :D

I read that you actually DO take manaband, which was the hat before (as it's still displayed in your guide right now). Interesting. I also read about the comet not being that great (anymore) and you take Archangel's staff last item now...? Wow.

It'a bit of a change-blow for me because it feels a lot different than the previous build... You don't think you need the Seraph's embrace shield early-ish? Unless you solely did it for the CDR alone.
Why doesn't Kog need CDR that much anymore actually? :)

I'll keep eyes on your subreddit, if you post the update about the experimental pages for Kog there. Thanks much again! (PS, with your build I even managed to make a Penta <3)

I like the new changes! 8.4 has been good for Kog'Maw in general.

Hey Aqua Dragon, your guide was referred by a friend who's been using yours for a while. (As I've been using his build which is actually from you!)
I must say you're a life saver. Ever when I changed my starting item to Faerie Charm and Mana crystal, the early lane phase has been so much easier for me.
However, i did start out building Liandry's first for the burn and ult poke. But that's aside from the point why I wanted to comment on the guide.

I've got 200k+ mastery points on Kog'maw AP only, I absolutely love it. However , with the recent mage item changes, it's been a bummer I feel. Liandry's seems to be out of commission as a core item now. Even though I loved it so much early on. However, Crystal scepter has been buffed. that's good. The new Morello is basically old Liandry's, except it lacks the burn sadly...

I'm really puzzled on if things are still well for him mid since the item changes. People keep saying I should give up and just play Xerath....I tried playing him but it's just not the same. I can't give up on Kog mid, I've always loved it. :<
I really, really hope you can find a solution after item testing if things still work out with the new item changes and then post it here. I would really, really love to read it over.

Howdy! Spurred on by your spirit, I found some time to fully update the guide once more.

I feel the new AP changes are completely manageable, and that Liandrys is not to be underestimated! Even without the raw magic pen on it, the sheer amount of base damage it adds over multiple shots (especially with Rylais) makes it still the single most damage efficient item for AP Kog'maw (I even redid all my calculations just to make sure!)

Happy AP Kog'mawing!

Aww! thank you for the reply and so, so much for updating the guide! I really appreciate you took the time testing and updating.

I'm happy to see you still consider Liandry's to be picked up early. I've tested running Morello early on (by skipping Liandry's first)I felt like it was lacking it really hard...
I've never taken Crystal scepter this early though, I'm curious to see how it goes. Is it really that better than taking Liandry's first? I know you can chain and ult hits are really easy to 'spam' a bit more, but Liandry's burn is soooo gracious. Even on squishies I feel. Farming CS also feels a bit easier landing the last hit with R after E.
But you've done the numbers so you must be right.
Though... missing the magic penetration by not getting Morello at all feels perhaps lacking too? I know, the rest of the item is meh on Kog. I feel you.

You also say that Void staff is not core anymore even if it gives massive magic pene. especially since that's priority. It's still in your example finished build, but I'm just wondering in general: If you do not get the magic penetration (missing from Liandry's now since you don't get Morello) or from void staff at all, will you still do enough sufficient damage?

Hey! How do you play around kat? And ad assassins? I seem to die in lane often when there is an assassin around:v I assume I would have to try a different build?

Aqua Dragon (42) | November 5, 2017 12:18am
Hey! A big part of it is just experience with the matchup. Exhaust or Flash are almost entirely enough alone to survive an attempt on your life. Once you have double Ruby Crystal, it becomes significantly difficult for them to kill you. And until they have their ult, they can't even reliably burst you down.

Avoid poke pre-6, and then post-6 aim to have both Ruby Crystals and then use Exhaust or Flash to escape death. Keep a ward on their side of the lane to keep track of their position though or else they'll just roam in response to your tower hugging.

Thanks! Are you thinking about any new build paths? I've noticed without the mana regen from the runes I've been running out of mana a lot! When I use prescense of mind, it really depends on getting that first kill fast!
