post-RED NL build?

On my night lord I followed this line and it worked out quite fine:

100: +1 shadow shifter, +1 quadruple throw, +1 night lord's mark, +1 sudden raid
101-110: +3 claw expert (30)
111-120: +3 dark harmony (30)
121-123 +3 night lord's mark (10)
124-126: +3 shadow shifter (10)
127-132: +3 showdown (18)
133: +2 showdown (20), +1 shadow shifter (11)
134-139: +3 shadow shifter (29)
140: +1 shadow shifter (30), +2 maple warrior
141-149: +3 maple warrior (29)
150: +1 hero's will, +2 toxic venom
151-152: +3 toxic venom (8)
153: +2 toxic venom (10), +1 quadruple throw (2)
154-162: +3 quadruple throw (29)
163: +1 quadruple throw (30), +2 frailty curse
164-172: +3 frailty curse (29)
173: +1 frailty curse (30), +2 hero's will (3)
174: +2 hero's will (5), +1 sudden raid (2)
175-183: +3 sudden raid (29)
184: +1 sudden raid (30), all free points

You may of course max maple warrior to 30 if you have/plan on getting decent combat orders.
It's also your choice whether to put a point on venom, frailty curse and hero's will earlier than actually starting to raise them. I assumed you wouldn't really be bossing before 150 though.
I hope it helps, if this is decent and you're going to write a sticky night lord build you may take this to use or as a base, modify it etc.

I'd consider using showdown a bit sooner. Specially with the new change that makes enemies killed by it still trigger the extra exp and drop. You'll have not only a stronger mobbing skill, but also increased exp and drop from it, making you reach the "max showdown" threshold faster.

And it also works on bosses now.
