I have been playing Mini Ninjas, and acquired the "Detect Kuji Shrine" spell. I tried to use it, but found that the little fireflies/yellow flying sparkly things that it creates move too quickly to really follow, and often it is easier to find the hidden shrines by just looking for the regular fireflies that indicate hidden surprises/secrets.
Am I just using the spell incorrectly? Or will it show me things that the fireflies don't?
