I wasn't accusing, I had just seen something like it in a list of "must have mods" for BG3.No. I found it towards the end of Act 2, I think. It grants advantage on all attack rolls, but disadvantage on all saving throws.
Edit: it's called the Risky Ring. You can buy it from someone at Moonrise Towers. So you could actually get it pretty early into Act 2 if you don't put off Moonrise Towers like I did.
