Rookie mistake POE2

[/img]Good people, I want to comment that I just made a mistake at the time of corrupting my cane, I had no idea that I could not improve the quality once corrupted and it remained at +6%, it is possible that I leave the cane as it was, I lose a lot of damage for that, it will not happen again, now I will read before doing anything!
PS: I leave you a picture of the cane, I really want to cry :(

Thank you very much for your time and thanks for this great game!
