There is a certain probability of injecting your target with "Fallen Flowers Chi" during an attack, with the hidden enemy waiting to burst forth, and causing a small amount of Soft Damage (there can be at most 2 bursts of Chi).
Flowering Branches Shaking Wildly:
"Fallen Flowers Chi" will bloom after 6 seconds, throwing your target's Meridians into disorder and interrupting his Skills, causing brief command lock out, and causing Yin Damage to your target and nearby enemies. Due to damage to the Meridians, your target will consume HP during each use of a Skill within 12 seconds.
