Definition of “Sustainability” in League of Legends?

Sustainability refers to a champion’s ability to consistently recover health through healing, regeneration, or other restorative effects. Strong sustain allows a champion to remain in lane for extended periods, maintain steady Farming, and avoid losing tempo through unnecessary recalls. Because they can shrug off poke and small trades, champions with good sustainability often control early pressure and dictate how opponents position in the lane.

During fights, sustainability becomes even more impactful. A champion who can repeatedly heal or restore health across Trades and longer skirmishes is much harder to push out or finish off, especially when combined with defensive items or regeneration-based kits. High sustain also influences objective control, as healthier champions can contest vision, rotate more frequently, and recover between engagements without needing to return to base. This combination of endurance and presence makes sustainability a valuable trait for bruisers, juggernauts, and certain supportive mids or bot laners.
