Baldur's Gate : The Sword Coast Chronicles : NWN2 Persistent World

The new traveling merchant at Beregost is selling a periapt of proof against poison very different from others. The left one is a normal one, and the right one is the one the merchant is selling. Is this intended?

Agreed, it should have another name.
But hey - devs time is limited and better used elsewhere. Like putting new or missing items ingame
