search disable and open locks are in the 90's with GH and Manual of Stealthy Pilfering (and 20 search item). I do have +3/4 skill tomes across the board and 3 martial Skill Past Lives.
I haven't come across any traps/doors/chests at 28 I can't do.
RE: Shadow Dodge it's amazing but yes you'll want Fort PL's (best from BF since they're passive). Shadowscalle makes it easy. I will say that after 5 epic PL's in this level set up (12/5/3) you don't HAVE to run shadow dodge. Some lives I've instead gone into Henshin for passive ki and some dex instead, and put more points in other trees. That opens up gearing slightly for less extreme fort numbers. In fact, I've enjoyed the flexibilty so much I may switch up the build to 12 Monk, 5 Wiz, 3X to try some other splits. Or maybe 9 Monk 5 Wiz 6 Ranger for sniper shot, more pos spell power, and Deflect Arrows/2 secs instead of 6. Deflect arrows in EE is godlike.
You can't really go wrong. This builds intent was max dex and resource minimization so I can put DPS on targets. It's been a huge success. And if you do try it, I implore you to run into a quest with 80-84 Dex in Shadowdancer, with Executioners Shot trained. Hit 10k, and line up some mobs. Watch them all die to a 70 fort save instakill with they get hit with 3-6 Shuriken all with a 35% chance of proccing it

It's a VERY viable trash killing alternative to Shiradi's Nerve Venom + Sense Weakness/No Mercy
