The first task he sets out for you is to help him (in other words, do all the work) get trophies from three "dragons."
Azdalin is a level 65 heroic^^^ big lizard that wanders the path in the breeding grounds in Düsteres Gewirr. He spawns when someone on this step of the quest gets to the island.
Gylton is a level 67 heroic^^^ drake that wanders around the hoards of droags and drakes, above the Gorg Pit at the bottom of the Sanctum of the Scaleborn. He has a lot of hit points and spawns almost immediately after being killed.
The best way to get the trophy from him is to wait until he falls asleep. When he is asleep he will not be aggro or attackable. Right click him to pluck a scale from him. He will probably wake up angry. Remain perfectly still and do not move. If anyone in his aggro range moves he will attack them and will not go back to sleep. Wait until he falls back asleep and try to pluck a scale again if you did not get one the first time around. Alternately you can kill him to take a scale.
HINT:You'll notice he's standing in between-ish two pillars. What you do is stand behind one of the pillars such that he doesn't have line of sight on you. No line of sight = can't attack you (but will wipe out anyone else in the room, stand perfectly still). Has worked like a charm for me and everyone I know. He'll go aggro when you try to pluck scale, but since he can't see you, he can't attack. So just pluck away at him til you get update. After you get it you can evac, or gate or just simply wait for him to go back to NPC mode (less than a minute), since he sees invis while in mob mode.
Additional Hint* you can walk to the balcony on top of him, scroll the camera view out, and pluck his scales that way - no need to worry about any aggro or sleeping.
Return to Fuzzmin. He gives you a Rusty Wurmslayer as a reward and tells you to go look for a weaponsmith to repair it for you.
The oak shaft can be found in the Sanctum of the Scaleborn above ( 23, 121, 307 ) /waypoint 23, 121, 307 where you found Gylton. Take the ramp at the south end of Gylton's room to the uppermost room. At the top of the platform above the pit there is a chest. Examine the chest to get the oak shaft.
