Posting this build upon request.
U23: Updated for U23. Biggest changes are Lots of Gear! And. The Harper Enhancement Tree, which brings INT modifier score to hit and to damage with all weapons!!!! I haven't actually TR'd into Human yet, so the numbers below may be off a little here and there and feat progression may be off. Let me know if you spot any errors.
U19: Updated for U19. Biggest change was race. Drow is best race for this build IMO, but human is a close second.
Updated for U17: Biggest change is gear! Entirely new gear set for lev 25 over lev 20 gear. I added a level 25 gear section to this post, I left the level 20 gear list as it was. Some chages to twists also.
U16's biggest change is more emphasis on defense. U16 Epic Elite quests are brutal if you neglect defense. I now have 25% dodge + 25% incoporeal + 20/50% concealment running on this guy all the time. You dont get hit much with all of these being separate checks for each incoming blow.
I have tried str based and dex based rogues pures and spalshed, but by far I like this one the best.
This guy requires a lot of hard to grind gear, but it is worth it!
My concept for this build started out a while back (when lev 16 was cap) as an INT based assassin. When I started this build most folks laughed and said no way it would work. LOL. My concept was to max out assassinate DC, with 500+ HP's, be able to hit most mobs on a 2, all while still being able to do all the trap stuff expected of a rogue, without fail. This build does between 80-90% of the dps that a geared STR based build does. That said, I gotta wonder why folks go STR based!!!!
Game play on this guy involves doing most of my DPS via sneak and assassinate. I concentrate on assassinating full health bar mobs, and then joining the main fight on an already engaged mob until my cool down for assassinate is reset, I then go into sneak and hunt down the next mob with a full health bar, rinse, repeat. I usually give priority to mobs in the periphery such as archers and casters for my assassinates. I also try to get lined up so I can hit two or three mobs at once. You can often assassinate 2 at once and rarely 3 if you get lucky with double strike, but the mobs have to be close together. For solo play I use Shadow Manipulation a lot and/or summon monster scrolls to get mobs attention, then stick 'em. I tend to use Bluff and Diplo a lot. All this while being able to do any trap and open any lock on any difficulty, without fail. I have a lot of fun with this guy!
Damage comes primarily from Assassinate and Sneak Attack Damage which on this guy is 29d6 + 12. As far as damage goes, it ALMOST does not matter what weapon you use, since sneak damage is so dominate. You can almost do as much damage with a spoon, LOL.
Anyway, Benchmarks for this build: at Lev 28: (assumptions: ship buffs, GH, haste, as equipped or using equipment described below, 3 rogue past lives, +6 tomes to all).
I do not include other (some easy to get) buffs in these numbers as I consider most of them either too hard to get (abashai cookies, house D pots, bard buffs, etc), too much of a pain in the ass to sustain (rage pots, scrolls of whatever buff, and other short duration buff pots and clickys), or too expensive (store pots, yugo pots, etc). Do keep in mind tho, that the below posted numbers can be even better. The only one of these I often use these days are the store pots, they last 10 mins and allow some flexibility in some aspects of this build, such as making up for lack of a +6 tome, or if you prefer a different destiny set up than what is described below.
Race Human. (36 pt build)
STR 27: (8 base, 6 tome, 8 item, 1 exc, 2 profane, 2 ship).
DEX 39: (15 base, 6 tome, 11 item, 2 insight, 1 exc, 2 profane, 2 ship).
CON 41: (16 base, 6 tome, 11 item, 2 insight, 1 exc, 2 profane, 2 ship).
INT 62: (18 base, 6 tome, 7 levels, 1 human, 2 capstone, 2 assassin, 4 harper, 11 item, 3 insight, 1 exc, 2 profane, 2ship, 3 epic destiny).
WIS 30: (9 base, 6 tome, 8 item, 2 insight, 1 exc, 2 profane, 2 ship).
CHA 30: (9 base, 6 tome, 8 item, 2 insight, 1 exc, 2 profane, 2 ship)
Standing Assassinate DC:
26 INT bonus (62 INT)
20 rogue levels
6 stealthy from shadowdancer destiny
5 measure the foe enhancement from assassin tree
71 Self buffed standing Assassinate DC
1 bard Song
1 yugo pot
1 store pot
74 DC from common and/or not too much a pain to maintain buffs.
5 from +10 more int from maximizing INT in destinies (+3 more), twists (+4 more), and epic feats (+3 more)
79 Assassinate DC
Higher than 74 and you really begin to move into PIA-to-maintain-that-DC territory. Requiring (IMO) major sacrifices in destines and feat selection, relying on others for buffs, as well as maintaining short duration buffs that are difficult to obtain, such as abashai cookies or house D pots, etc.
71 is what I consider the best practical DC as all you need to rely on is yourself (and your ship), not make major sacrifices to attain, and not have to worry about refreshing pots or other short duration buffs. I sometimes use store and yugo pots for a 73 DC, but the cost and/or detriments are not worth it or needed most of the time.
80+ DC is possible, but, again, is not practical as it requires hard to acquire or very short duration buffs such as abashi cookies or house D pots, etc. 74 is about the best practical DC one can easily maintain, IMO as of U23. Going all out to 80+ DC really gimps you in other areas that matter in destinies, twists, feats, and enhancements.
~ 910 HP (often ends up to be over 1000 with commonly used party buffs)
Armour Class: 78
Reflex 79 (high 80's vs traps)
Will 52 (useful, even in EE content with Slippery Mind)
Reflex save is very high without really trying so you could drop insightful reflexes and settle for a low 60's reflex save and get some other feat of your choice. But having that high reflex save sure is nice in end game EE content (almost required, I'd say).
Max ranks in Balance, Bluff, Concentration, Diplomacy, Disable Device, Hide, Jump, Listen, Move Silently, Open Lock, Search, Spot, Tumble, UMD, and one other of your choice, I put mine into swim
Trap Skills: (at lev 28 using +20 items, +5 exceptional items and/or gear described below and self buffed only. Other buffs such as bard/yugo/store pots, action boosts, etc, will make these somewhat better.)
Disable 111 + 1d20
Open Lock 91 + 1d20
I have not failed any trap or lock with these numbers to date in epic elite quests and raids.
Other Skills (as equipped at lev 28 below)
UMD 55 (good enough to cast level IX scrolls at 100% success rate)
Move Silently 78
swim 71 (LOL) try it, its a hoot. (with a +20 item)
1 - toughness
1 human bonus feat - two weapon fighting
3 - precision
6 - insightful reflexes
9 - improved two weapon fighting
12 - improved critical: pierce
15 - greater two weapon fighting
18 - dodge
21 - epic toughness
24 - imp sneak attack
26 - perfect two weapon fighting
27 - watchful eye (I love this ability!!) or overwhelming critical or sneak of shadows
28 - toughness
Rogue special feats:
Slippery mind (this really helps to shore up this builds greatest weakness, the low will save)
Human Racial tree: +1 INT and healing amp
Assassin Tree: All 6 core abilities, +1 INT x 3, Assassinate, measure the foe III, Crit accuracy III, crit damage III, killer II, knife specialization, sneak attack training x 4, stealthy III, Envenomed Blades III OR Damage Boost III.
Harper Tree: first 4 core abilities, +1 INT x 4, Strategic Combat II, Highly Skilled III, Versatile Adept x 4.
Thief-Acrobat Tree: first core ability, fast sneaking III.
This part of the build is often changing for me. Many good things here. You could actually go all int in twists and main destiny and hit a 75 or so standing assassinate DC if you like, however, I recommend AT THE VERY LEAST maintaining 71 standing DC + 25% dodge somehow. There are many ways to do this by tweaking this destiny to your liking. It becomes even easier if you get lucky with a +6 int tome. I use shadow manipulation a lot, it is really excellent.
Shrouding Strike III
Cloak of Shadows I
Shadow Manipulation I
Improved Ivisibility I
Grim Precision I
Shadow Form I
Sealed Soul I (immunity to level drain, you need this for tyhe new abbot raid, mainly. If not running Abbot raid, put these points into Grim Precision)
Sense Weakness (use the following 3 if not an epic completionist)
Brace for Impact
Hail of Blows
I also use a greensteel healing amp stick when self healing (a heal scroll heals me half my total HPs or so).
For ranged weapons you get repeater crossbows profs from first 4 core abilities from mechanic as well as int bonus to damage!!. I went for this as early as possible because a good repeater with int bonus is really powerful at early levels. Greensteel repeaters at lev 12 on up is also very, very good. This is a nice bonus when ranged is required.

For DR bypassers, 2 Celestia's works on almost everything needing bypassers. I also carry a good set of portal beaters.
This guy is a lot of fun for me because blindly running ahead is NOT the thing to do with this guy. This guy requires smart play and accomplishing things by thinking outside the box, which for me is the biggest appeal for this character, and a nice refreshing change from the norm. There is almost nothing more satisfying than listening to the big bad barb ***** because you decimated his precious kill count. LOL. And you did most of it with one swing / mob
Max Theoretical Assassinate DC for a rogue:
Max assassinate DC = 85 for a Helf, 84 for a drow elf. (this DC is far from practical since it requires a lot of very short duration and very hard to get int buffs. It is here just for reference.)
20 rogue levels
6 stealthy (shadowdancer tier 1)
5 measure the foe
40 INT bonus from 90 INT (18 base, 6 tome, 7 levels, 1 human adaptability, 1 arti dil, 3 action surge, 2 capstone, 2 assassin, 4 harper, 11 item, 3 insight, 1 exc, 2 yugo, 2 ship, 6 epic destiny, 4 twisted, 3 great int, 2 completionist, 2 litany, 2 store pot, 3 house D pot, 4 abashai cookies, 2 bard song)
