Berek if you can get it... but easier is Starfall, which has pretty decent stats and good damage as a one handed, and the quest is fairly good exp with what you have to kill. Its also fairly easy to get just killing skellies for the AQs and whatnot.If you harvest a lot, or have some gold to through around, I also suggest getting a good 2 hander if you group with other tanks and are often support tank or dps (which we can do alright as!), I ended up getting a pristine forged steel great sword.. and that thing put out some nice dps all the way up to level 30
Starfall and the greatsword were my two weapons from early 20's-30.
