Zehtuka's Horn

I just got Zehtuka's Horn after beating The Great Zehtuka in Magni The Bison's challenge. I was interested to see that it is customised, which kind of limits its usefulness and worth as an offhand. I guess there must be other customised offhands but I don't know of any myself. Are there any others?

Any of the rewards from the Bonus Mission Pack are customized.

Anything from bonus mission pack....
i think the Bison cup might be im not sure.
Intersting thread shame i can't give more answers.

Bison cup isn't, no.

quite a shame that zehtuka's horn is customized
i saw Olaf Olafdottir with a similar weapon offhand equipped
the horn has a nice skin and quite a useful stats for lets just say a monk or something

Yes, I knew about the stuff from bonus mission packs, but I meant items that you obtain in the game, not by typing /bonus.

the bmp items aren't given by /bonus. game of the year edition and pre order items are /bonus.
