I'm not sure what the deal is here, and my initial google results didn't return anything relevant:

I have an item floating around in normal account-bound status, that I will never use, a level 3 necklace named "Heirloom necklace". On my NB, who's in Champ level content, it says it gives him 1.3k bonus to max health, which is nifty. On every OTHER character (IE characters that could use such a thing while leveling), it says it gives <500 HP, which is less than even a pretty significantly under-leveled health necklace. Thus it is not useful to me, and I would like to get rid of it.

For some reason however, I can't find ANY way to get it out of my inventory. I can't sell it, even to a merchant, and I get an "This item cannot be destroyed" error when I try to delete it. I can put it in my bank obviously, but that's still an inventory slot taken up by something I'll never use. I suppose I could drop it onto one of the alts I made that I never play (Hello, Magplar from launch!), but that still seems like more of an "ignore the problem" than "Solve the problem" solution.

Anyone have an idea or suggestion? It's not like 1 unusable inventory slot is going to destroy me, but it's rather peculiar that I can't get rid of it in any fashion & its stats vary so widely between different characters.
