I Want To See A Teamup Between Karthus and Lucian

Karthus is allied with Thresh though. Granted, there is mild disagreement on how to handle the dead, but for the most part, Karthus doesn't care. However, Karthus doesn't like Lucian, he actively encourages Lucian to die and meet his Senna.

What about Kalista and Lucian?

We already have an Item that reduces Lifesteal ()

Yet we still need one that can reduce Wifesteal to counter

Karthus cares about the dead, so I see the potential to save souls from Thresh. But he doesn't like the livings. Not sure what would happen.
