If you kill a lich and a phylactery with an AoE the relic dies twice and the lich is still respawned.
This is because - to my knowledge - the trigger for Eternal Life does these checks: EVENTS A champion dies CONDITIONS Triggering champion has ability (Eternal Life) = TRUE AND Triggering Champion is race (Lich) = TRUE AND Number of (Phylactery) in play is larger than 0 ACTIONS Set Respawn = (Target point closest to (triggering champion)) Kill (Relic matching Phylactery type) at Respawn Reanimate (Triggering Champion) at Respawn DestroyGroup (pdg_Respawn) This is a sketch but generally the game doesn't check the condition of the relic. You'd most likely have to drop the entire thing inside another loop that'd check HP of a relic and if it has 0 or less HP, it'd check for another one if possible, but this most likely leaves room for more errors as the game logic tries to resolve the situation.
