Hello

You should rewrite this build.First, why did u choose revive?It's one of the most useless spell in the game.Very long(540 sec) CD.Take Flash , its mutch better.Other in ability sequence tab you learn Defile on lvl 8.Have you heared about its passive.You don't have to use it and if you kill a unit you gain manna.You shoud learn it before u reach lvl 5.

Secondly,masteries.+6 magic resist and +6 armor is not too much.You waste these points.Put them into the utility tab.

"Normally in the course of 10 seconds you can use 10 Lay Wastes. That's 2400 damage (rank 5, single target, 0 AP)"-enemy has got magic resist don't forget it.And who can guarantees that all of Lay Wayte will damage?No one.

Others said all of the misstakes.Try to rewrite it.

There's a difference between constructive criticism and misinformation/opinions with no evidence. So far I've backed up every thing I've wrote with details of the functionality or a rejection of something simply not true. Do you trust someone who has played free week Karthus once on Classic? Or someone who has played well over 300 games with Karthus on Classic with around a 70% win rate and about 50 Dominion games with around a 80% win rate (100% if you don't count horrible comp 3-4 squishy AP top games) win rate since I've come up with this build.



If Requiem didn't have a cool down you wouldn't need either. Guardian Angel is the very last item in the build. It should be a miracle if you make it that far in the game I've personally only built it once because games that go on that long are extremely rare. But when you're at that stage in the game the score is most likely 10 against 15 points left on the Nexus, both sides control 2 points, mid is neutral. The next fight decides the winner if you can control a point for just 10 seconds you will win. Now combine the GA passive with your Death Defied passive and Revive with ultimate and then maybe another Death Defied and you have the best stall in the whole game by far. Just long enough to win. Getting to GA is extremely rare and you will most likely never even build it.

A person who cant take criticsm is a bad author. Also, why het GA and revive? You can just stall people with ult...

Wall of Pain shreds a ton of armor and magic resist if you rank it. Not only does it increase your damage it increases the damage of your entire team the massive slow and length bonus are just extra. Did you even look at defile? Each rank increases the damage by 20. 20, that's it. While each Wall of Pain shreds 5 armor and magic resist more that's roughly a 3-3.5% damage increase on afflicted targets at that stage in the game. When you factor in the increased damage you do with your Lay Waste combined with the damage your team is doing it will typically be higher than 20.

But the most important thing to remember here is that Defile is a close range skill, you need to be within 550 range to use it. Wall of Pain has a cast range of 1000 even slightly longer if you tilt it with a longer wall length. So Wall of Pain can be used to attack from outside the range of any retaliation, while with Defile you need to suicide rush the team to do anything. Overall 1 rank in Defile when you get a catalyst is good, but Wall of Pain is the better skill to rank over Defile.



Summoner spells are mostly useless in Dominion. Insuring a kill with Ignite, or slowing and weakening an enemy for a turn around kill makes very little difference in the game. Kills and deaths have very little impact, so the Flash you used to get away from a sticky situation is wasted because you surviving had very little impact on the game. Even losing a team fight and a point because the team had more aggressive summoners won't make a difference in the long run because in less than a minute you will win the next fight and get back your point, then the team will have to wait 3 minutes before they'll win another fight. Revive is the least useless of all of the useless summoner spells. A quick return and more up time will actually have an impact on the game while all other summoners will not.

About Good Hands, every single alternative is lack luster. It really doesn't matter where you put that 30th point. I like 12 seconds more up time. If you prefer a very insignificant hp boost go for it. That last point does not matter in the least bit.



This is flat out wrong. Lay Waste has a .5 second DELAY. That means when you cast your q there is .5 second delay until your bomb explodes, but the cool down starts the moment the bomb is placed on the ground so by the time it detonates there is only .5 seconds left on the cool down. Lay Waste has a 1 second cool down that can be decreased by cdr down to .6 second. This means when a q detonates you only need to wait .1 seconds to cast again.




Not only does this statement prove you did not read my guide it also proves you have never played Karthus. Every single good Karthus player knows about the Defile cool down exploit (Ahem, I mean feature). Read my "Why Cool Down is Essential" chapter.

So, you would rather have a bigger slow than more damage in these 'teamfights'? You can only use 1-2 revives in dominion. Why the hell do you get good hands and revive at the same time? Revive does NOT win games. Only use it for summoner level. Lay waste has a .5 sec cd and you will NOT be able to put much more Lay wastes in fights. Spam toggling defile will do nothing for your damage. Overall, a bad guide.

The only time you will ever run out of mana is during a team fight. After a team fight if you need mana you don't even need to attack minions the natural mana regen combined with a single health relic should get you back to full mana before the next fight. You need the increased mana and passive restoration effect of Catalyst before you put your first rank in defile because otherwise you will run out of mana within the first 15 seconds of poke, harass, and the eventual team fight.

I don't put a point into defile until level 8 because that is around the time I usually grab my catalyst. The level 8 is a ballpark time to put points into your e you can level it as soon as 5 if you somehow got enough money in the first team fight, or as late as 10 if you are getting destroyed.

By the time you get Rod of Ages and Morello's you should already be level 18 or very close to it so mana and skill rank is irreverent at that point.

I didn't say in a team fight. What if you just got done with a fight, are oom, but don't have enough time to go b or do anything? Sit there and wait for the team to come beat on you with you being useless? Take 1 minute, go kill 5 minions with autoattacks. Between the 100 mana and your regen which would probably be rather high between Morello's and Catalyst you can actually do something.

Don't want to be near them to use it? Don't be. I'm just saying a single point in it before level 8 could actually help in a dire situation.

Also, unless you never team fight anywhere near any points whatsoever, you're more than likely going to hit a minion or 2 with a q.

You should not be within 550 range of an enemy in the first few fights. You should be in the back spamming q's, your e is useless because you're not close enough to use it. If you are close enough to use it, a reasonably intelligent team will kill you before you make an impact.



So when you run out of mana during a team fight you start auto attacking and q'ing minions? I'm starting to wonder if you've ever played Karthus top on Dominion.

Just because you don't want to use the toggle on defile doesn't make it a completely worthless spell early. Oom? Just q or auto attack a dying minion. Congrats, you got some mana back. Rinse, repeat.

What's wrong with the spell order? Defile should not be taken until you have the mana to sustain it, also you should not be close enough to even use Defile until much later into the game. Morello's is mostly for the 20% cool down. Did you read the "Why Cool Down is Essential" part? Did you read why I have Revive? Did you even read anything?
