Ok.... what the heck.
I'm wearing the cursed thick gauntlets.
I "dip" the gauntlets into a potion of holy water.
"The potion of holy water glows in a sick green light for some seconds. You dip the cursed thick gauntlets into the blessed potion of poison. Nothing happens."
.... I'm obviously *wearing* the gauntlets since they're cursed - how the heck did I poison my holy water?
Edit: I searched projects for "Thick Gauntlets", didn't find something like this, and put in an RFE.
