Search Tor'Watha to the southeast of the Farstrider Retreat for Spearcrafter Otembe and bring Otembe's Hammer to Arathel Sunforge at the Farstrider Retreat in Eversong Woods.
The Amani and the sin'dorei have a long history of mutual dislike and open hostility. That doesn't prevent me from appreciating a fellow craftsman's work, <name>.
I've come across pieces of Amani weaponry and I must admit I'm impressed by the quality of their work. It is rumored that Spearcrafter Otembe wields a magical hammer that is so light and well-balanced it allows him to work with great dexterity and efficiency.
If you bring me this tool I'll use it to craft you a weapon.
