III. Promote Conditions & Clash Avoidance
The Sanming Tonghui explicitly states: Tian-Yi Noble Star dreads Earthly Branch clashes (Six Clashes) and Voidness (Xunkong). If the Noble Star branch undergoes clash or falls into Voidness/Punishment, its protection is severely diminished; conversely, if aligned with Prosperity, Imperial Phase, or Celestial Virtue, its blessings are multiplied.
