the bug that if you apply any kind of effect to it and the effect ends, it reverts back to its basic stats? Just throwing this in because you haven't mentioned if you use weapon coatings or dip between casting and noticing the error.
I don't *think* I applied any coatings to it, but I'm only 99 percent sure on that one.
Still a good call, as it would explain what happened with the non-ring version - though perhaps taking that Reprieve potion does count as applying an effect to the weapon in this case (though it really only applies an effect/a condition to the character who uses the potion). Another possibility would be effects derived from other items/mechanics. I do use the Ring of Arcane Synergy on her and that thing triggers quite often in combat - and if Arcane Synergy counts as an effect applied to the active weapon (which it kinda is), that might be another explanation right there.
This should be very easy to test since I still have a ton of Reprieve potions stockpiled (thanks, Mr Bugbear-vendor!) and it's not that hard to trigger the Synergy-effect.
