Question on Robe of Greater Acid Resist

[UnderwearModel]

Correction: My brain just told me that the picture in my head is red so I believe it is a CLOAK and not a ROBE.

I received one of these yesterday. I was going to sell it, but I have never received an item like this. My character is a cleric and will not be using the CLOAK.

I believe it is CHArisma +1, Greater Acid Resistance -30 off each acid attack. No race restrictions, but the level is either 11 or 13, I forget and I cannot check the game as it is under going maintenance to fix all those lag issues in Giant Hold. (oh wait, that was AT&Ts fault)

My question is;

Do I Sell it? To me, the auction shows that these items are not that popular, so not much use in the game.

I would like some of the more experienced players opinion.

Thanks in advance.
