User blog comment:HeroGaming/Karthus Overextend or not to Overextend?/@comment-4315699-20120216221004

This is by observation from my good friend who mains Karthus. build a bit of tank mid, You need the Rylais and a defensive item to make sure you can keep up the chase with your aura active, using an early tear of the godess helps keep your mana high. In team fights You should do all you can to hit with your Q without being in front. they will attack you but that is fine, if you die and the fight is still going on, make sure your aura is active and cast your ult to give your allies an edge and maybe get some kills. Into the late game you should have proven to the enemy team that focusing you doesn't work because it will only invoke your ult with impunity. At that point you shouldnt be afraid to get in range to use your aura on the carries seeing as youll never outrun them. This is just my observation of course, He almost allways has most damage and almost allways has a positive score by a long shot.
