Mechanics Back to Top

All about the Karthus mechanics 

When playing Karthus, you should spam his q, the smartest is to pick a minion alone for the double damage. Early game you can have a bad time, but mid game you will start getting tanky, if you follow the right build. His w is used to get away, chase somebody or get a lot of damage from your q, because it reduces the enemy's magic resist. When late game farming, use your e, because it will do so much damage, the minions will only survive for seconds. Make sure to not use your ult to fast. When somebody is low (doesn't make sense which lane) always check his health, and your damage first. Be careful because the person can have a health potion, shield or very fast regeneration (for example the baron buff health regen boost). So when your teammates want your ult, check health while going under your tower, if it's low enough, cast it. Under your tower you'll be safe against any attacks. You can also use it as a very good way to stop a chase fast by just killing the person while you are chasing. When dying, try to walk into the enemy so you can use your passive very strong, you can also cast your ultimate in your passive, but if you want to do it, you have to do it right when you go into your passive. Because your passive will last 7 seconds and your ult casting time 3 seconds, so it is good to do it early in your passive.

This guide is made with the information I think is needed for playing Karthus. This guide is completely based on how I play and if you dont like it or if you aren't doing good with this guide, it isn't my fault. The guide is built up from my experience with Karthus. Thats how guides are made.
