Here is the build in question.
Fighter and Barbarian are the mainstay of this build, with Cleric dipped for access to domain powers and for Turn Undead. If I were making an evil character, I'd probably take Blackguard levels instead (5 of them?) and subtract 2 levels from Fighter. Some tweaking would be necessary.
For the deity, I chose Grumbar as Luck and Darkness are both really good dip choices (Blind Fight and Luck of Heroes? HELL YES!) but either good deity choices exist. Darkness is pretty necessary for Blind Fight, so I'd probably pick a deity like Shar or Selune if I wanted to roleplay the religious aspects (and I probably will pick one or the other). Wood Elves are another good choice for race and can worship Erevan Ilsere, though I'm not sure this is the most roguish character I've ever invented.
Skill points are going to be highly limited. That 100% needs to be understood. Thankfully, we don't have any skill point taxes (No PRCs), so we can simply spend them as we please. This changes if an evil character with the Blackguard class is used instead of Cleric.
This Aasimar setup can't really afford to shift any points away from STR, DEX, or CHA, as that would make getting EDM harder or near impossible. WIS is already at minimum. If more skill points are desired, a hit to CON is the only option, and less than 12 CON for a martial character is pretty much chief among cardinal sins in NWN2.
The spoiler below contains the text I put in the "Build Info" section on the link. If you haven't read it, or would prefer to read it here, well... Here it is.
Hidden: show
1. This build probably isn't going to be the best of all ranged builds or anything, but it will have a high attack bonus and a high damage bonus. Its raw damage output is, in fact, probably higher than a Stormlord's. I have my doubts as to whether it'll be as strong as a solid Manyshot Assassin HIPSter with a crossbow.
2. You can boost its static damage in little ways. For instance, bring along a wand of Divine Favor before kicking dungeon doors open; it's not worth casting mid-fight, but just before busting a room open? Sure. And 5% extra to hit never hurt anyone.
3. Like many builds, this one operates best with friends. It's not a particularly sturdy fighter, nor does it have any meaningful spellcasting, and its defenses would be much helped by a friendly buffer. It DEFINITELY wants a bard buddy if possible - more static damage = great, always great. It should, however, solo just fine so long as it's played smartly (and with a decent shield equipped).
4. Its saving throws are a GLARING weakness. Holy poop, they're bad. They're worse still because the build can't fit Steadfast Determination, and worse-worse still if you don't take Luck of Heroes.
5. Combine point 4 with a whopping 12 Constitution for HP, and... ouch.
6. I think one of the biggest challenges for this build is how late it blooms. Cool, you get EDM... at level 29. Cool, you get Northlander Hewing... at level 29. Up until level 29, this build will be pretty average at best, I think. Only once EDM comes into play will its true power be recognized, and even then only in spurts.
7. Finally, you may notice this build does NOT grab Whirlwind Frenzy. This is on purpose. Haste can be procured by other means, and I don't relish the idea of being 10% less likely to hit my enemies because I enter rage. Standard rage will do just fine.

Okay. Please let the critique begin. I especially want to know if there are any big, glaring weaknesses I failed to spot, or critical feats that are missing. (Again, Brutal Throw is "Use Poison" on NWN2DB, Thrown Weapon Mastery is "Imp. Unarmed Strike" at 27, and Northlander Hewing doesn't arrive until level 29.)
But the point is, if you have a character that you like to play as, then you will overcome the experience issues.
