Find the rest of the bow parts and see if you can put it together.
Obtain the other four parts of the mighty bow to go with Ritsy's lucky string
Obtain 2 mechanical servos (You need to find a key in the water in the begining of Spirit's Resonance. It is really hard to see, it is at the bottom of the pool (use gnomish diving goggles), on the side closest to the exit at ( 409, 116, -253 ) /waypoint 409, 116, -253. Left-click the 2 tall golems in the room to turn them aggro, level 90^^^. They drop one servo each.)
Obtain a golden bow shaft (Dropped from The Gorgon Wrangler ( -260, -296, -612 ) /waypoint -260.00, -296.00, -612.00 at the bottom of the Underfoot portion of The Hole.)

Go click the anvil at ( -26, 121, -239 ) /waypoint -26, 121, -239 in The Hole. It is next to the daily faction quest giver.
Speak to Kardaxian ( 6, -102, -820 ) /waypoint 6, -102, -820 in The Outer Vault (you need to speak Serilian to get the update). (The Outer Vault is marked No Merc, so unless you are a super character of some kind it is not likely you'll solo it.)
