I'm coming back to the game after a long hiatus and I've never played a Monk before. I've done a lot of reading on the class and builds and I want to build a Halfling Ninja Spy (Dark path) for fun.

I'll probably go Crane or Tortoise and focus on Water stance to boost my Wis. I'll also be taking the Halfling sneak attack enhancements to make use of Unbalancing Strike.

Base Stats:

(I have access to +3 tomes from the store.)

S 14 (all level-ups)
D 16
C 13
W 15
I 11
Ch 8

A +3 Int tome will give me a 12 Int at level 3 and 13 Int at level 7 to meet the req's for CE. I also want enough skill points to throw some into Hide and MS.

Feats:

This is where things get tricky. A halfling monk gets 10 feats. I would like to take Combat Expertise and Imp Trip to boost my AC when needed but also take advantage of Unbalancing Strike. But Improve Sunder would also be nice to lower Fort saves of enemies.

Here's what I'm thinking:

TWF/Imp TWF/Gr TWF
Stunning Fist
Power Attack
Imp Crit
Toughness
Combat Expertise
Improved Trip
Dodge (for Ninja Spy)

That's 10 but no room for Improved Sunder. Is it worth dropping something for Imp Sunder?

Thanks!
