League of Legends Energy System: How Energy Champions Work in LoL
Energy is a resource used by certain champions instead of mana, displayed as a yellow bar. Unlike mana, energy has a fixed maximum cap that doesn't increase with level, making resource management crucial during combat.
Base energy stats:
- Maximum energy: 200 (Shen has 400)
- Regeneration rate: 10 energy per second (50 per 5s)
- Full regeneration time: 20 seconds (40 seconds for Shen)
Champions that use energy:
- Akali
- Ambessa
- Kennen
- Lee Sin
- Shen
- Zed
Key characteristics:
- Energy regenerates faster than mana
- Cannot be depleted over time like mana
- Limited maximum pool creates strategic constraints
- Ultimate abilities don't cost energy
- Ability costs often decrease with level
- Champions have energy refund mechanics
Ways to increase energy:
- Akali's Twilight Shroud (increases maximum energy)
- Crest of Insight buff
- Presence of Mind rune
Energy restoration abilities:
- Akali: Twilight Shroud
- Kennen: Mark of the Storm and Lightning Rush
- Lee Sin: Flurry
- Shen: Shadow Dash
- Zed: Living Shadow
Notable facts:
- All ninja champions use energy
- Lee Sin is the only non-ninja energy user
- Returning to spawn restores energy percentage-based
- Previously, Dominion mode had increased energy regeneration (12/second)
Energy champions must carefully manage their resource during fights, as depleting their energy pool can leave them unable to cast abilities for several crucial seconds while it regenerates.
