Pc on +1 staff 20% (NOT MASTERY)

I have a +1 divine favour 20% chance, it is NOT a mastery. it is the real deal . Even though a mastery is just as good, theres a small collectors market for these babies, and ive seen deaths +1 go as hihg as 80K how much could I get this for (ill be selling it here, not in game)

1-100k depends on the buyer but the truth is you will have a hard time to find buyers
