Hehe, fun little glitch I was told. The only way it can be fixed is if you log out...
BTW I have no staff out
How to do it?
1. Get a staff with an Aura power. Doesn't matter which one, I happened to use the one with Dark Aura.
2. Push seven or click your special dark aura symbol.
3. Immediately after you click it or push seven, press ESC to put away your weapon.
4. If this is done fast enough, you will have a blue/green/red circle following you until you log off!
