League of Legends Energy System: Complete Guide to Energy Champions
Energy serves as an alternative resource to mana for select champions in League of Legends, displayed as a yellow bar that caps at 200 (with Shen being the exception at 400).
Energy regenerates at 10 per second (50 per 5s), making it more reliable than mana but limited by its low maximum capacity. This creates a unique gameplay dynamic where champions must carefully manage their ability combinations to avoid temporary resource depletion.
