Okay, the revised (and, IMHO, much improved) version of the Blessed Sneak. Kudos to Grizzled_Dwarflord, Stravinsky00, and Mithdradates for the excellent suggestions for improvements. This should be easily playable from level 1 to 40 (I don't know about PvP, as I only build with PvM in mind). Here it is:
21)Rogue 12: GRT DEX I (22) 22)Rogue 13: Defensive Roll 23)Cleric 9 24)Cleric 10: GRT DEX II (23)/ DEX (24) 25)Cleric 11 26)Rogue 14 27)Rogue 15: Epic Weapon Focus 28)Rogue 16: Epic Dodge/ DEX (25) 29)Cleric 12 30)CoT 2: GRT DEX III (26)/GRT WIS I (17) 31)Cleric 13 32)Cleric 14: DEX (27) 33)CoT 3: GRT DEX IV (28) 34)CoT 4: GRT WIS II (18) 35)Rogue 17 36)Cleric 15: GRT DEX V (29)/ DEX (30) 37)Rogue 18 38)Rogue 19: Crippling Strike 39)CoT 5: GRT DEX IV (31) 40)C0T 6: Epic Prowess/ DEX (32)
*These could be anything of your choice.
Domains: I'd go with Strength and Trickery. Strength mainly for the Divine Power buff at levels 3 and 4 (as well as 5 with the Silent Spell feat) Trickery gives the Invis line of spells, ending with the excellent Improved Invis.
Final AB dual-wielding and unbuffed with a mundane weapon is: +38.
Buffed with Divine Power, it rises to +43 and gives you 3 attacks at your highest AB, 2 at your second highest. You'll get even better AB by stacking more Cleric buffs on that.
Hit Points: Not a strong suit with this character, but you have Endurance/Empowered End. to get yourself a few more.
Lots of slots, and lots of versatility with the couple of metamagic feats to fill up the spellbook with useful buffs.
Cast Ultravision and load up on Darkness spells to generate sneak attacks.
You get an excellent Darkfire boost on two weapons, Bull's STR to up your damage, all the good Cleric buffs to augment AB/damage, and a good number of spells per day. The 15 Cleric levels serve to max out many of the effect/level buffs as well as providing decent spell durations.
Sneak attack is an acceptable 10d6.
This could proabably be relatively easily adapted to a Halfling build with a couple of adjustments. You'd net +1 AC and +1 AB due to small stature, but pretty much be restricted to daggers for dual-wielding. Now, if only I could get this to work with a Dwarf...
