I picked up the sabre "Resolution" immediately enchanted it with corrode damage and gave it to Edér to use. 
When I later used Resolution on the statue I had to unequip it and put it my inventory before the coversation would trigger (This may be intentional, not the main issue) and when I got Resolution back it had been stripped of the enchant (That is pretty annoying). 
  
Thank you.
