I have said it before, and I will say it again. You need to aim for 30+ Wisdom end game for a monk to have passing DC's on your finishing moves, weither your a Light Monk or a Dark Monk.
I see no exceptional Wisdom in your build, and you are in Sun Stance, which is actually less swings(doublestrikes) than Wind Stance, which to me, means less DPS.
This cloak the other guy was talking about is not +3 Profane Strength, unless you wear 3 of the 5 items for that set.
I'd suggest tossing your gear around to fit more of this setup.
Head: Helm of the Mrornan ~ +7 Wisdom + Yellow Slot
Robe: Red scale (Toughness & +1 Exceptional dex)
Trinket: Litany of the Dead
Necklace: Shintao Cord
Gloves: Spectral Gloves ~ +7 Dexterity + Yellow Slot
Belt: Frenzied Beserker ~ +2 Damage on set bonus.
Boots: Madstone
Bracers: Leviks, Bracers of the claw (set with gloves), or chaosgardes, or jids when self healing for the extra healing amp when you switch to fire stance to heal up.
Cloak: GS minII hp
Goggles: mentau's Goggles ~ Personally I'd go with the red fens goggles for the +2 exceptional wisdom and true seeing, but thats just me. I don't see my Monk crit often enough to really put to use a Seeker item unless I'm stunning mobs, so I use Seeker handwraps of Stunning 10, on bosses I go for more DC's for my finishers, or if I'm not tanking, I wear my Tharnes.
Ring1: Kyosho's Ring (shintao monk) w/holy burst
Ring2: Frenzied Beserker Ring w/shocking burst
This setup would lose +1 strength, from not wearing a +7 item, however that is offset by eating a +3 strength tome, (20th shroud if nothing else), however it gives you the chance to raise your wisdom easier.
Str - 38 (18 base + 5 level + 6 item + 3 tome + 1 litany + 2 enhancement + 1 except +2 rage)
Dex - 26 (15 base + 3 tome + 6 item + 1 litany + 1 excp)
Con - 26 (16base + 6item + 2tome + 1litany + 1excp + 2 rage - 2 stance)
Int - 8 (6 base + 2 tome)
Wis - 32 (14base + 7 item + 3 tome + 1 litany + 1 enhancment + 2 exceptional + 4 stance)
Cha - 14 (6 base + 6 item + 2 tome)
Whenever your madstone boots proc, you'll be a 40 Strength.
this leaves you 1 build point left over.
Touch of Death = 10 + 20 + 11 = 41 DC
Stunning Fist = 10 + 10 + 10 + 11 = 41 DC
Quivering Palm = 10 + 10 + 11 = 31 DC (trash mob worthy, atleast on non-epic)
At level 20, your Jump will be maxed, without putting any points into, with the Devils Battlefield clickie. Balance will also be plenty high, with a +15 item. I personally suggest that you do the math, see where your balance will end up, before you place points, you want it to be atleast 21 at cap.
Max your concentration, maybe your spot, UMD is useless on a Monk, talk to a high level raiding Monk in game, and you'll find out why.
This is my personal opinion. Everyone went with the Metaru Str Dark Monk build Pre-Mod 7, though I disagree'd with it then as well. Nerf's come and go, I forsee Touch of Death staying the way it is currently on Lamaniaa, however, if enough people complain that this isn't the way it should have been from the start (which is what i think, it should have.) then they might change it to a scaling damage, however I doubt it.
I've always believed that a Monk, regardless of path, should keep atleast a 40 DC on Stunning Fist. Luckly, 99% of the finishing moves that Monks have, rely on their Wisdom (only 2 don't that I know of), and for these 2 that don't, a Charisma of 16-18 is perfect
Take it or leave it, up to you.
