Well, at lvl 6 making 30-80 and hour may sound pretty weird well, i made a new Nelf and was running round like normal, and questing. Found a rarish named enemy. He drops a weapon called "Keen Machete" which is the highest dps weapon at level 1. So therefore best level 1 twink weapon. Many bankers also would like this as it looks quite nice. This wep can sell for anything from 10-40gold. Onto the guide.
You have two options....Make a new Nelf char get it to level 5+.
Or use a existing alt and get to teldrassil.
The enemy npc is called Threggil. He can be found in the cave north of dolanaar. Threggil - NPC - World of Warcraft He is found at the yellow dots. The drop is 100% and he drops numerous other things like linen etc not really worth much in comparison to the machete. The biggest catch is he spawns every 20 minutes. So i would rather suggest making a new char, and keeping him/her at the npc's corpse so you log in every 15-20 minutes and kill him. Get a few, sell them, or kill and mail as its not to far away from Dolanaar.
I searched for Keen Machete. So I dont think this is a repost. If it is im sorry
Edit: I have realised some people enchant level 1 white items with imba enchats eg. +40 stam and +12 agi on legs to help them level easier, i guess this wep would be the best to enchant with +15 agi or crusader while leveling.
Good luck, and happy farming? If it can be called that :P
