Credit to the guy who made the guide, which is stickied on BSmarket.

You get TT at 100 via quest, so SP should already be maxed by the time you get it. o:

Thank you. I checked SW's NW guide, and I just had to laugh-my-f'cking-ass-off at their guide. It was complete and utter garbage, because most of the stuff I saw did not made sense, as the person who made that guide had very little to zero experience with that class. . . . <_< I'll use that 'build' as a guide for my own build, though mine will differ in some areas.

2nd question: Does anybody even bother maxing Vanish? Also, is it like how Shadowers uses DS into their attacks? Is it worth it? Are there any videos to show how a NW uses it at Pap, Zakum, or any other bosses?
