There are a few builds around like this
The difference is this focuses solely on Crossbow - yes it loses out on melee and bow multishot - but can focus on just one weapon (Light, then Heavy Repeater)
1 Barb Level taken JUST for +10% movement (and Barb Toughness) - rage adds very little
Very good kiting build
Obviously, an accomplished trapsmith with skills to spare
Damage is sneak attack and sniper enhanced
Sneak attack:
24.5 Rogue Level 13 (7d6)
6 Halfling Guille (level IV too expensive: 8 AP for +2 damage)
12 Attack training
4 Int Bonus - naked
3 Int Bonus from +6 Item
---
45.5
Good UMD even with low starting CHA:
23 skill
2 Skill Mastery - note - passed on Imp Evasion because it will likely only help on a 1, and opportunist is mostly melee
1 +2 CHA tomb mod
--
26 naked unbuffed
3 +6 CHA item
3 Golden Cartouche - or other Competence item
1 Big Top (+3 for Epic)
1 Voice of the Master
4 Greater Heroism
2 Inspire Competance
3 Rogue Skill Boost
--
43 Fairly easily (resurrect Scroll is 44 DC) - more with a bit of work
