Circle of Death

Per level³

• Try Circle of Death with a high-healing Zac build.⁴
• Stacking Bard chimes near each other can deal a large burst of damage when an enemy comes near, though the strategy is not very viable.⁵

• Health regeneration can trigger Circle of Death while its user is at full health.⁶⁷
• Circle of Death damage works with Righteous Fury's ability damage.⁸
• Mundo, Tahm, and Zac use Circle of Death well.⁹
• Aatrox's healing while attacking and Gwen's passive healing can deal additional magic damage through Circle of Death.¹⁰

Heal and Shield Power increases Circle of Death damage from Warmog's health regeneration, even though it does not increase Warmog's healing; this may be a bug.¹¹

• In the eight-teams-of-two format, Naafiri's old W passive healed her for each dog she had out and could make Circle of Death deal enough damage to one-shot nearby enemies; whether this interaction still works after her changes is uncertain.¹² Earlier Arena format
