You can get another claw from the quest the Maple Admin gives you to raid the watermelon fields. Basically, you should have dark sight, so use that inside the fields, and it becomes a cinch to get the 5. After you get it, talk to Agent E, click the 'Talk to Agent E' option which should be at the bottom, then ask to teleport to headquarters. From there, talk to Agent M and finish his quest, which will give you another pink flowery tube.
Make sure you check which one you pick, because you don't need a dagger.
Also for builds, I'd get 1 flash jump in the beginning so that you can mess with that for all your mobility needs. Then follow the other builds posted earlier in the thread. Since you already used your first sp on mastery, level and do this.
Talking about this class makes me want to make a night walker now, thanks a lot. <_< ):
