Not sure it exists, couldn't seem to figure out a means of making it work. But I love the Potion Charms and effects, but I think it would be cool if they could be enabled only while set in a charm slot for curios. Or if there was a config option to disable their functionality while in the base inventory. To avoid charms stacking an such from a balance perspective.

Is this fix available in 1.18.2?

don't believe so

Dang. No worries! Thank you for the response! We'll update one day for sure! Can't wait.
