My first and only 50 is Weaver.
I levequested almost all of it. At 48 I was like most, getting mostly 40's and 45's. So I set Hasty Hand and started punching them out.
Took around 40 Levequests all to Uwilsyng. A 40 and a 45 got me 6400 exper, 7-9 Hasty Hands. If I got a 50 I would synth it, if I didn't it was a 5 minute trip in and out.
47 to 50 took 3 hrs.
