i just read up a bit on this thing.
apparently its a UBWS blade, but the chance of you getting a stealable is based upon your stealing and your meelee skill only matters in the actually hitting of the monster. Seems that part doesnt matter too much though if i were to jewl up and just go do some low level spawn (since you can get stealables from anything).
So, if your interested, i could give it a shot for you. i dont have any meelee (but could jewl up a bit to smack slimes haha), but i do have 120 stealing. If you want, ill give it a shot and see how it all works out.
PM me with the details if this sounds good to you.
