Darkheart

Suggested Champions
Here is a list of champions that could use Darkheart efficiently.

The Brawlers, Seranok and Shedletsky: Both make great usage of the Darkheart. Hell, its even a must have on Shedletsky, due to his high reliance on basic attacks. Seranok also benefits from the Attack Rest Reduction (and of course, the Skillz), due to his Momentum mechanic.
