Raid: Shadow Legends – HP (Health Points) Auras boost your entire team’s health in the area that their Aura relates to but only if you put this champion in the leader position. HP is required for any champion to help them stay alive as long as possible but will only increase the damage potential of champions with HP scaling skills. The only Aura that will work against Clan Boss is an All Battles Aura. Aura’s are generally stronger on Legendary Champions and weakest on Rare Champions however this is not always the case!
You retain this additional Aura bonus even if your leader dies.
