My 'plan' for my Night Walker.

In the end, it's your character and its up to you how you build it. But below I'll help you out a bit with my own insight.

However, the build and your attitude regarding it seem to come off a bit selfish, and you should probably consider why other characters and players would want YOU in their party quests. Don't get me wrong, I'm not being mean, but the whole "they can give ME haste" thing won't help you out in the least.

On other notes, vampire is an insane skill but if you plan to only PQ I can't think of many where it would come off as very useful without many mobs. CPQ would be an exception, Vampire is a beast there - you don't punch with it and so mobs that are up in your face are as good as dead, not to mention you won't need to pick up HP potions. Regrettably, it requires mastery for the damage to be very reliable, but I still strongly recommend you reconsider putting it back in early on in your build. Another Con, though, is that it may not be very good at PyPQ, if I remember correctly when I tried it out there on my NW I didn't get any "Cool!" bonuses, which actually led to me getting kicked out before I got to 500 kills. Even adding a point into Avenger didn't help that very much, so I hope that you plan to PyPQ with a party, because soloing will probably not work out.

This is all I needed to know ^. Reason I asked if it was effective at Pyramid PQ was because I originally planned on solo'ing Pyramid-PQ and getting near 1k-2k kills per PQ just for the EXP. I don't know of any Arans (in my guild or BL besides my own Aran...) that's around lv 30-50. So most likely, if I do choose to get Vampire, it would only be useful to me at Pyramid PQ. Of course I am maxing my Vampire and Mastery, but I was going to have both of those a bit late. I didn't get Drain til early 50's on my Assassin (2 years ago?). I'll most likely add in Haste around 52 or so. Going to modify my build now, but I probably won't update it on this thread. Thanks for the critique and advice!

EDIT: Actually, going to cap FJ at 13 (because of what I learned in another thread), and leave it there til I find the need to max it. Until then, I'll work on getting my Crit to level 15, booster to 6, while putting SPs into Vampire and Mastery.
