I think he’s mistaken. Those relics are green, so clearly they boost HP. (or maybe stamina)
My grandparent’s had that same uranium glass set. They used one of the ones with a lid as a candy dish. I haven’t thought about that in close to 40 years.
FYI it’s totally safe to have and handle. Infact a report published by the US Nuclear Regulatory Commission in 2001 stated that uranium glass is considered to be safer than household electronics. but it is recommended that you do not eat or drink off it in the unlikely event that you chip or scratch it and ingest some of it. If you go thrift shopping or to antique shops bring a small uv light with you. If the glass glows green under the uv it’s uranium glass.
If you really want that passive poison effect, you need to get fiestaware: bright orange/yellow ceramics where the concentration of uranium is way higher and it’s used as the glaze!
It’s known to leech into acidic foods, such as tomato sauces with pasta.
I also feel like we can also add antique top hats to this; I recently found out that my grandfather’s childhood top hat, which I used to play with all the time growing up, contains mercury nitrate
Not really an HP drain. More that they apply a very weak disease that stacks the longer it is applied. If it stacks enough it begins adding other status debuffs.
