Quite good. While Layla’s shield is not as strong as Zhongli’s, it still takes second place in terms of raw shield strength, with a noticeable lead over other shielders. Her shield is created with her Skill; this means she does not need to devote many stats, if any, to Energy Recharge, allowing her to focus on HP%.  Layla can even substitute the team’s healer slot, as her shield can withstand much punishment with good investment. Against enemy Cryo damage, Layla’s shield is even more effective than Zhongli’s shield.
