I was wondering, for those units whose auras trigger whenever others in their aura are healed (such as Spirit Walker Luthor), can the auras can be triggered during the enemy's turn? I'm talking about situations when the others in their aura are also in the aura of a friendly Blood Knight Victoria or Holy Defender Faye, such that they get healed during the enemy's turn (lifesteal auras if different story because lifesteal auras heal during your own turn).
I'm asking cause I have not yet gotten by Blood Knight Victoria or Holy Defender Faye to 5* and I am wondering if they could be good in a triggerfest squad centered around Spirit Walker Luthor.
