I was thinking so , but I was the host in the few times I recreated the bug . So im not sure , hence I posted it . Still very annoying that the other bug is still around also , unless theyre the same thing . <| sep |> I am a long time Karthus fan and I love using him and he has been one the main champion I play when I get top and the team doesn ' t really need something beefythe enemy team is full of squishiesHis strength comes from his insane range which allows him to be pretty safe and a lane bully at the same time . Karthus is a nightmare for melees . The long lane also allows him to chase down people who overextend . His pushing power forces your opponend to stay in lane while you can pressure the whole map with the ultimate . A short guide I ' ve posted as a comment a few days ago # LaningYou should learn how to lasthit with autos . It ' s really important as you can ' t apply pressure to the enemy if you use all your spells and mana to farm . Use QE only when needed . Aggressive Preferably against melees and low pressure enemies or once you got a lead . Farming with autos to keep the wave frozen , with Q and Autos if you want to push . Use your Q to punish the enemy for lasthits . Just place it where they will have to move to get the next CS . If they dodge that , they just lost a CS . Passive Stay at max range and lasthit mainly with Q . It doesn ' t matter whether or not they push you under tower as you can get 100 % of the CS with proper Q management just need to kill the ones with too low hp before they get targeted . Alternate between those 2 playstyles as needed . Use a single tick of E double tap it to get lasthits you barely missed with autos or to prep the caster minions to be lasthit with autos under tower . # TeamfightsYou got insane DPS . Attack wahtever is in range and spam Q . You got great perma slow with rylais as well . Use this to kite the enemy when they try to engage and use it to peel for your ADC if needed . Don ' t be afraid to flash in the enemy team on a suicide mission if you are sure you ' ll get an enemy carry for it at least aoe on everyone else . This is a thing you ' ll learn with experience . Hint R can be used before a fight breaks out to force the enemy back example before baron . # GeneralFarming is really easy and one of the most important things on Karthus . A Karthus without items is useless as he doesn ' t offer much utility . Don ' t go double mana item . EVER . Either Rush RoA or go tear into Rylais usually depends on back timing and wether you need the hp and sustain or not . You waste way too much of your power . Karthus isn ' t weak early . Early AP makes him snowball really hard as it means his R will hurt instead of tickle for an other 10 minutes . I hope that helps a bit .
