Overload Champion

Overload Champions are a Champion type that regenerate health and can't be hurt for long unless stunned.

Stun them with Arc Jolt, Void Suppression or Stasis Slow, seasonal Overload artifact mods (auto rifle, pulse rifle, rocket launcher), or Exotics like Le Monarque (Poison Arrows), Divinity and Thunderlord; perks Voltshot, Chill Clip and Cold Steel also work. While stunned they stop regenerating, so use power weapons or Supers; keep applying disruption afterwards.
