Soul Shear or Tengu Strike

Isn't Tengu Strike worse than Shikigami Haunting?

Yeah, definitely. His point was when he was fighting more than 3 enemies though, haunting only hits 3 while Tengu hits something like... 10. Though to be honest, the spawn in LHC doesn't really warrant Tengu at all, it's very rarely above 3, so haunting is better completely since it is faster and doesn't require mana.
