The one thing that stops me from starting one rightaway, is all the buffing after each rest. I wonder, though: once you start MotB, won't most of your buffs be useless, since they generally cap at +5, while items at epic levels provide better bonuses? (I.e. Weapon Enchants, Armour Enchants, Spiderskin, Greater Resistance, etc...) This is the build I have in mind: http://nwn2db.com/build/?113865 I'm looking for ways to keep the 26+ BAB and also get 30 CL.
It depends on which Buffs.. AC yes, but give up Mirror Image? NEVER. There are also several other Buffs I consider mandatory (beyond Haste): Protection from Alignment, Night Shield, *Enlarge Person, Ghostly Visage, Blindsight, Shadow Shield, Premonition, (and Energy Immunity if Required). *Enlarge Person for the added +3 damage (though with also the -1 attack penalty and AC). Pre-Fight Buffs: Ethereal Visage, Tensers. Be happy with the CL you have. Alternatively - improve the CL you have and have Kaeyln make you a potion of Divine Power (actually a LOT of potions). (requiring you to have her select Brew Potion at her first feat/level-up.) Yes, Thorsson is correct - Combat Insight. The alteration of Dragonslayer to Bladesinger is also interesting. Of course if you do go the route of Divine Power potions then consider other non-High BAB classes - like potentially the Daggerspell Mage.
Combat Insight is a good catch, but it didn't pop up in my Epic feat choices. Bladesinger is my prefered choice as well, but it has higher prereqs, IIRC.
