Restore

While Fu Xuan is still active in battle, Misfortune Avoidance is applied to the entire team. With Misfortune Avoidance, allies take 10% less DMG. When Fu Xuan's current HP falls to 50% of her Max HP or less, HP Restore will be triggered for Fu Xuan, restoring her HP by 80% of the amount of HP she is currently missing. This effect cannot be triggered if she receives a killing blow. This effect possesses 1 trigger count by default and can have a maximum of 2 trigger counts.

After the Technique is used, all team members receive a Barrier, lasting for 20 seconds. This Barrier can block all enemy attacks, and the team will not enter battle when attacked.
