While messing around with talents and weapons I noticed something. You must be specced ret I believe this is a bug with the "Sheath of
light" talent. What you do is swap your weapons around. I continually swapped Savage Gladiator Greatsword and Savage Gladiator gavel. You loss the effect on zoning or logging out.
Unfortunatly I haven't had time to test if its visual or fully working.
