This guide saved my marriage. Best Karthus NA

Hello! Very well-made guide. my friend!

I am curious as to what runes I should take and I would like some clarification. Dark Harvest usually scales better, and by fighting a lot you actually gain an advantage. I've weirdly won a lot of games even with a lot of deaths just because I dealt A LOT of damage in teamfight and my team was able to clean up. I haven't done a lot of testing and I'm not sure if farming and scaling is better than playing risky while maintaining a low bounty (similar to Baus strat).

Please do let me know! Best of luck!
