*Massive dmg output.
*Decent surviveabiltiy with this build.
*Very good farming.
*His ultimate have unlimited range.
*Can kill people after he is dead.
*Difficult to play in teamfights (because of focus)
*Kinda hard to use ulti in the right place to right time.
*Use alot of mana!
*Easy to counter ( Knockbacks like Headbutt and stuns. )
*Low magic resist
*Veigar's Primordial Burst will destroy you completely if you have a lot of Ap!
This is your mainly used skill. Remember, you can spam it about evyre 1 second. A good harass spell early game!
When you get this in level 5 (or earlier, but i like lvl 5) you can go for a killing blow. It slows the enemy and reduce their magic resist!
This spell have a passive that give mana each kill you get. Whenever a enemy starts to get to close for you, simply pop this and their health will disappear as ice in a desert.
This is the spell many want karthus for. It can heat evyr enemy on the map and take abou 250 health in rank one. Evyrtime someone on the team say "ULTI" you want to check theyr hp. if they have under 200 health you can pop ulti. if not let it be. you must think about their magic resist or if they have summoner spell heal or soraka/taric close to them. I have 160 sec cooldown so it should not be wasted to harassment!
I have choosen Magic pen in Mark for obvius reasons. 1# i can harras much more and do alot more dmg in Early/mid game. 2# you take more dmg than without Magic pen.
In Seal i have picked 0.065 Mana regen pr 5/ per level because you can Lay Waste more often in lvl 1 than without mana regen, of course in level 2 you pick Defile for the passive that gain you mana eavyrtime you kill something.
Glyph i have choosen 0.99 =1 AP in-game in mark because you get stronger early game.
Next time you return to spawn pool you should have gotten catalyst the protector and then return to lane. when you have around 1750 gold you return to spawn and buy and or start with a
After you should buy fast!
Now you want to increase you're health a little more for extra survival
Now that you have,what i have calculated around 500-550 AP. you should get more magic pen and maby some magic resist. So i use to go for some magic pen and magic resist, Other good choices are : or
This far in a game is realry but if you get this far and get a good amount of money you could sell you're and get a for increase mana and a bit more AP.
Full Core build
As alternative you can switch with a for some magic resist and some health. it also have a great passive that make you block one negative spell every 45 seconds.
Requiem this is the spell you always put a point in when you can = level- 6- 11- 16.
Defile i find this the best spell in late games. mostly because it have sick dmg and often get kills with this. In late game i usally have over 1700 mana so that should hold for defile at least about 1 minute=60 seconds.
Wall of Pain I max this spell last of all spells. still it is a very "important" spell go get kills in mid-lane.
From level 1-6 :
1. Lay Waste
3. Lay Waste
5. Wall of Pain
Sivir Is very hard to lane against. mostly because she have much more range than you have and its easy for her to harass you while taking down creeps with riochet
Also she have Boomerang Blade have a very long range and can hit you twice. so if she toss Boomerang Blade make sure to avoid the second hit by walking to one of the sides.
Ashe is hard because of her slow frost arrow that make you never get close to her and can take dmg with defile on her. she also have Enchanted Crystal Arrow wich stun you in about 3 seconds, and after that she will spam you with frost arrow so be very careful against Ashe
Morderkaiser Is very strong in mid lane because of his shield wich he can get by hitting enemies or creeps with his abilities. This makes morderkaiser a very hard hero to be against.
Soraka is not so often midlane, but she can destroy you're kill by healing him/her with her Astral Blessing or Wish wich heal Aoe just like your ultimate! You will also have to think about her passive that gives more magic resist when a teammate is close to her. be careful and make sure you get atleast one kill with your ulti. it have 160 seconds cd in rank 1!
So this is how i would go:
Can get away in teamfights much easyer. also a good escape spell!
Can counter gank and more map control!
Other good choices :
A great escape spell if you need to escape!
Get you back into lane faster and then gain level faster.
Gives you mana, wich you need but remember the passive on Defile
its okay because you can heal yourself and stay in lane longer, but i think there are better choices
its a okay spell to get out of CC + defile works if you have it on while you are stunned.
Terrible choices :
a tank can use this!
if you are thinking about this: you are ****ing dumb. sorry to say it.
would not ever use it on karthus. the only time it must be useful is baron or dragon.
No! You will need to get out of trouble much more than a bit more dmg so i will recommend Flash or Ghost
This is a great spell if you go "**** my life, karthus" to die even more! but you have your passive that 20% less deathtime.
*Karthus is squishy!
*He can deal massive dmg and take a good amount of dmg if you follow this Guide/build.
*Get blue as often as you can!
I hope you enjoyed this guide for karthus.
