Should You Roll or Pull for Fu Xuan?

As a five-star character, Fu Xuan is an outstanding defensive ally who can absorb party damage and replenish her health. She can also increase the Max HP and Crit Rate of her team members. This brings a different dimension to your potential team-building options, as Fu Xuan and a healer could seriously support a couple of glass cannons — or you could use her as an alternative to a healer. In fact, with her later Traces unlocked she can apply healing to allies on top of her existing defensive attributes.
