Not Updated For Current Season
The masteries shown here are not yet updated for the current season, the guide author needs to set up the new masteries. As such, they will be different than the masteries you see in-game.
I think karthus is one of the best character.
(this is why i like league of legends there are so many best characters)
the reason i like him so much is because once your level 6 u feel like ur owning the whole map. Karthus is the only guy u can kill whyll going shopping.(well mabe teemo but anyway)this build works best for me. I tried many builds but nothing worked as well as this.
u will have good mana and good AP. thank you and be free to suscribe.
with these ruins you have a lot more chance to survive
i dont get why ppl waste ruins to get like 20 ap
its better to get ruins that match its color
Marks are good in magic pen,armor pen,attack speed,attack damage,ability power etc.
seals are good in armor,health,dodge etc.
glyphs are good in magic risistant,mana,cooldown reduction etc.
quintesses are good in everything.
i go 9/0/21 like everybody else.
offense: Karthus uses AP and witch ever champion who uses AP need Magic penetration.Also u get 4% cd reduction whitch is pretty helpful. Archmage's sawy will give u some extra AP and extra AP is always good eh?
defense: I actually was considering this because karthus is very squishy but i decided to not.
Utility: the usuall
these items work perfect.
-Meki Pendant: u need mana regen dont u?
-health potion: u need to live. u dont want to go back every 5 seconds to heal.
-Tear of the Goddess: A great source of mana regen. Starting from here u wont go out of mana if u play right.
-Mejai's soulstealer: Any champion who uses AP needs this no excuse and it is very easy to get stacks with karthus cus his ult so u will have +15%cd reduction in no time(unless u are dying a lot).
-Sorceres shoes: I was thinking Boots of swiftnees but i tried it and this worked better.
cus ur ult is ur source of damage and being fast doesnt help anything with ur ult.
-Rod of Ages: i was thinking this or Rylai's scepter because i needed life and this was better. cus it gives u mana witch helps u with ur Archangel's staff's passive. Rylai's slow passive is useless, cmon in team fights whats the point of slow when your enemy is gonna be dead anyway. what? when they run away? well u got wall of pain and if that doesnt work u got ur ult so i dont think u need to worry about that. i can imagine also ppl saying "u wont get the benifit of the passive if u buy it that late."karthus is very good at farming and killing champions so if u play right u will get it in no time.
-"Archangel's staff" : A great great great item i think. it gives u mana and AP which is both very important to all mages and most of all karthus. Did u every had an experience u had no mana so u cudn't use ur ult? it is ****ed up and that just a small reason u shud get this. The amount of AP it gives u is amazing specially when u get another staff
-Zhonya's ring: i was thinking if i shud get another staff or this but when i tried this game more handy. 125 + 25% AP is like "thank u lord thank u." Also ppl dont use or dont know how to use this items active but if u use it right u can spare ur life many times.
u can escape from nunu's ult, karthus's ult and many other attacks ult ect..
-Archangel's Staff: Amazing AP and mana
u own everything
