Fengar, The Lord of Darkness is a custom champion in League of Legends.
Fengar's abilities have no cost related to them. His secondary resource bar tracks his unique mechanic: Dark Energy.
Fengar starts the game with 100 Dark Energy and can have up to 100 ( + 50 × Awakening's Ranks) Dark Energy. Fengar will generate 5 Dark Energy whenever he hits an enemy with a basic attack and 10 Dark Energy whenever he lands his basic abilities. Dark Energy does not decay idly.
