Hello this is my first post so please dont shoot me if its not good
The item we are looking for is Throat Piercers... the only twink thrown weapn with agility.
And the vendor you can buy it from is Erelan, the poison vendor in Tranquillen.
The throat piercers sell from Erelan for 1s50c
You can make 10g or more by selling them on horde but you will make more money by selling them on alliance
You will need to buy the throat piercers on your horde, mail them to another horde character waiting at a neutral auction house, then get a friend to buy them and give them to your alliance. Now you can sell it on the auction house for however much they are going for on your realm.
Throat piercers are rare and spawn, at the most, every 4 hours. Sinister scimitar also spawns in throat piercers place occasionally so be prepered for a lot of checking.
Once you have the throat piercers on your alliance make sure to let everyone know by telling them in trade channel put them on the auction house for a reasonable price (cheaper than any others on there but not to cheap)
And now wait for them to be bought.
Sorry if this is a repost i couldnt find any guides about this on here though.
