Does ITD work when it is already on the item, for instance Eaglehorn? I remember someone telling me one time that Jah does not work for pvp but if the weapon already has ITD, it does. Is that true or was the guy full of it?

Items for trade:
Windhorn, Eagleforce, Doomfather, Grandbringer, Harlequin Gaze, Vampirecrest, Gladiator's Valor, Arkaine's Bane, and Shaftstart

Looking for Stone of Manald rings. Also, I want Hearld of Arreat and Zakarum's Face.
