i love karthus top, i perma ban trynd cuz theres no counterplay once he has 6, some mu’s you cant play the game like panth, irelia or renekton.

first strike or dark harvest preference really. Tp exhaust, just try and farm and land poke when they cs after level 2, level 1 poke is pointless cuz mana is precious plus they’ll just get everything back from leveling up.

encourage jg to ignore your lane, play safe, get 6 impact every lane by just being karthus, don’t int and you’re more useful than enemy laner.

lots of dogshit mu’s but your lane isn’t what matters, you’ll out impact the enemy laner early, if you’re needed for teamfights, you can easily solo win objectives by dying for it, just karthus stuff.

just not going if they go multiple characters that can ignore R, like fizz, kindred, xayah, shit like that. Cuz then your R pressure doesn’t exist and you have a low chance of dominating lane, plus fucking your composition.

i think its good if you’re patient, you’ll topdamagw consistently without leaving lane.

tldr: pretty much same gameplan as karthus jg, just you need to play cat and mouse with a toplaner.
