Here's a breakdown from a pure Monk build I'm working on. Aside from the racial/class bonuses, you're probably missing several important sources.
Weapon To-Hit:
020 Class Base Attack Bonus (handwraps)
005 Epic Base Attack Bonus
022 Weapon enhancement (15 + 7 Magic Fang) 015 Weapon enhancements
023 024 Accuracy item
010 023 Insightful Accuracy
042 STR 046 WIS bonus
004 Shifter: Destructive/Overwhelming Shifting 003 Aasimar: Fight the Wicked 3
001 Harper Agent of Good
003 Warpriest 004 Shintao Studies 4
004 Divine Cursader Just Cause / Spear of Light 003 Shinto Meditation of War
005 Prayer (luck) 004 Fury of the Wild: Spirit of the Beast
005 Bless 004 Morale: Greater Heroism augment
002 Guild Ship Proving Ground
002 Potion of Prowess
002 Legendary Dreadnought: Weaponmaster
003 Legendary Dreadnought: Honor
001 x1 003 Fighter past life x3
003 Dragon Disciple past life x3
003 Arcane Enchant Weapon past lives x3
006 Primal Past Life: Ancient Power past lives x3
002 Scion of Arborea feat
003 Shattered Device 2pc bonus
001 Reaper’s Offense I
001 Reaper’s Offense II
002 Reaper’s Offense IV
010 Eerie Aim feat
-02 Yugo pot (Essence of Betrayal) (I don't use Yugo Pots usually because cbf getting the favor)
003 Prowess/Next Fall
003 Artifact (Sora Kell)
001 Follower of Path of Light (Sacred Fist)
002 Curse of Major Prowess
-05 Power Attack
Also a handwraps build, but 1 SF/14 Clr/5 DL Razorclaw. Green is bonuses shared, red is don't have and white is a different bonus.
Seems like the main thing I'm missing is Fighter past lives and main stat is lower (yours must be at least 102 to get a 46 mod, mine was 95). Also I'm using a Charisma trance (used both Warpriest with Dragon Lord at the time because the combat DCs stack and could use while raging) so the insightful bonus is lower too.
Base to Hit = 186 (vs 190 for you),
Critical bonus = +20 (3 Crusader, 15 Seeker item with Curse of Major Masterworks, 2 Prowess)
Sneak attack / flanking bonus = +13 (Dark Hunter x1, 12 Deception item)
Temp: +2 while in an Action Boost, +15 from Terror, +15 from Destruction Domain, +6 from Ravager: Fury, Sunder 10%
Don't know why the builder says accuracy base is +166 then. Seeing as I came up with this set myself (almost, thanks Nic) feel better about it now
