The Epic Arcane Trickster - Ro(10),Wiz(7),AT(10),NN(3)

Description
This is an example of an Epic Arcane Trickster. To summarize: BAB 18 8 attacks per round with Perfect Two-Weapon Fighting Level 9 spells Single Epic Spell Vampiric Feast 13d6 Sneak Attack Damage Near-max: Disarm Device, Open Locks, Tumble, Diplomacy, Search, Spellcraft. Very respectable: Use Magic Device, Lore, Concentration. The main goals of this build are: 1). Maximize sneak attack damage and reach Epic Precision asap. 2). Maximize arcane spellcasting power. 3). Maximize important skills such as Disarm Device, Open Lock, Tumble, Use Magic Device, Diplomacy, Concentration and Spellcraft. 4). Attain Perfect Two-Weapon Fighting asap. It's a very fun build to play as you are near a pure-thief in your abilities and a pretty decent spellcaster. Download Reeron's spellpack in order to unlock the real power of this build; sneak-attack ranged spells. With such a high dex you will *never* miss and with the high sneak attack damage and Epic Precision you will cripple most enemies instantly (remember most ranged-touch spells have NO save). BAB is close to a pure thief with Greater Heroism and Cat's Grace to enhance your prowess beyond what even they can achieve. Sneak attack damage is crippling; maxing out at 13d6 only 2d6 less than a pure thief's.

Fortitude save is horrible however there are plenty of magic items that give immunity to poison, disease, death magic and the like. You will need to stock up on these or you will be doing a lot of dying.

I specialized in Necromancy for the bonus spell that specialist get and because the Necromancy touch spells work well with this build. Flame Arrow is real nice too.

This build is great for getting around behind people and dishing out the sneak attack damage multiple times a round and can tank in a pinch with Impromptu Sneak Attack but without Feint can't do it for long.

The 6th level of Wizard is necessary to reach BAB 11 early enough to take Greater Two-Weapon Fighting Prior to Epic levels (so you can reserve your Epic Feat for, well, Epic Feats!). The 7th level of Wizard is necessary to reach full 9th level spellcasting (effective caster level 21 with Practiced Spellcaster).

Post 27th level you could ditch the NWN and take more Wizard or Rogue levels instead. More Wizard levels would gain you Persistent Spells feat while more Rogue levels would get you another Epic Rogue feat. You could also burn a feat and take Martial Weapons which would allow you to take Eldritch Knight instead. I like the +10% movement, high BAB, 2d6 sneak attack and Aura that NWN grants you at level 3 though.

Post 30 you can continue swapping Rogue and Wizard levels making sure to take Wizard levels on the odd levels (so you can get more Epic Spells) while using your bonus Rogue feats at every 3rd level for anything you like.
