Question about Zehtuka items...

So I came across the horn in Crystal Overlook the other day quite by accident... I couldn't figure it out so I went online to see what it's used for, and I couldn't find anything that said. I did find out that there are (or were, most of those posts were oooold) a whole lot of other people like me who can't figure them out so I understand if it's still a mystery. What I know now is that there are three other Zehtuka items (the pack, jug and shortbow) and that you can use both the shortbow and the pack, which is pre-upgraded and looks like the charr bag, but what about the jug and horn? Is there any point to having either blocking a spot in your inventory/xunlai or can I just trash em/avoid picking them up? It's ok if it's just one of those guild wars mysteries, but I would like to know if it is. I apologize if there was already a thread or more on this but I couldn't find one so I figured I'd post. Hopefully I chose the right forum too, I'm still a little new to guru . Thanks in advance for any answers !


Edit: Thx all for the answers . I may have to go out and get the rest of these now that I know what they're for. Happy gaming!

The jug can be double clicked like any alcohol drink in the game.

Have the horn with you when you face him in the norn tournament and it will be replaced with a green offhand item called Z's horn.

.

Carry the Horn when doing the Norn Fighting tournament. If Zehtuka is an opponent he will give you a replacement horn that is a held item similar to the Bison Cup

The horn is automatically customized to the character who obtains the item in the tournament.

So unless you want this item, or have a hero that could use it, there is no need to keep the horn. Can't sell it or use it with other characters.
