Let me give it to you straight.
This issue staff cannot fix. You are among the selected few players on Frostwolf with an Abnormality.
I seen some stuff, Horde Mage who can use create ally and horde portals, Warrior with heal spell, a Hunter who can tame humanoids, and other creatures, Hunter's who can res people in their party with pet spell, A warrior who's crit does not go up no matter what, etc.
You're case is nothing different from the people I met.
So far there is only one solution; deleting and restarting your character. I tell this to others, but with all the work they've done, they won't reset their character and will remain how they are now.
All in all, I am sorry for what happen to you mate.
PS:
There are others who are surprisingly bugged to gain a HUGE advantage. The only example I can bring up is Kufango, we use to think his damage was for show, but the reality was he was bugged; for his damage was abnormal and he had a few spells not met for players. In this situation, Warmane WILL react because this is gamebreaking; only brushed the player off to not do it again, so the only course this hunter took was to leave the server.
Cheers.
