So I just started playing Old World Blues and I found a weird blue glowing halo looking thing. It says it regenerates health, but it only seems to work when I first equip it. When I put it on I get one HP, then nothing. Its not that big of a deal since the autodoc thing in the house they gave me will heal me, but I was just wondering if this was a bug or something.

When I first found it I thought it was going to be a gamebreaker, and now am wondering if I should just sell it or not.

Why not keep it for the look? IIRC there is an upgraded version.
