This section is dedicated to using Xinyan as a shielder for her team.
Xinyan's Skill grants you a Pyro status upon contact with the shield. No matter how many times you switch characters, it will still apply Pyro every time you switch while shielded. This allows you to cleanse most elemental statuses that have been applied to you.
Shield uptime is also crucial to maximizing her Physical/Shield Support capabilities. If you have neither nor at least [C2] (ideally [C4]) on Xinyan, you may want to build her as a DPS instead of Physical/Shield Support.
Generally not recommended for Pyro applications, as the pulses only happen at Shield Level 3 and are not very efficient at breaking Cryo shields.
