I'm going to make this simple.
Command permission: ghost.toggle
Plugin description: Turn into someone who can fly around, yet your body never moves. Skeletons will not target you, but they will target and hurt your real body!
This is extremely useful for having a look inside someones base without people seeing you walk in there!
Or maybe you want to follow a hacker around!!
Warning: What you will see as a ghost is what is being sent to your body. If you explore too far, you will no longer see any chunks loaded, and no mobs will spawn, etc.
