Yeah. This build is so i'll remember this build better. Not looking for votes, but if you feel like telling me how this could be improved, that'd be cool.

Karthus can be loaded early with max cdr and it works to great affect.

First, give it a try.

Karthus' ult, with max cdr, can get to a 72 second cooldown. The overall damage dealt to the other team soars. great success, and turret pushing glories.
