Lost an ehancive deringo runestaff in the Arena

[Winter]

I think it was a well-balanced deringo runestaff or something like that, I put it in my disk (stupidly) because my containers were full then dismissed the disk 1 minute later and forgot it was in there, it was south east of the room where the gentleman gives you your arena package. I had 411 cast it on with lightning flares and it added mana, spell aiming, and wisdom. I was going to chalk it up to loss but it's been the communal runestaff for my lower level characters so I thought it would be worth checking to see if someone found it.
