This build is simply amazing. Sitting in the G.Hall staring at the skills from the balth rewards DOES help.

I'm not sure if I'm the first one to think of this. I know the spirit bonder was already here, but i kind of modified it just for this UW duo. I started off trying this on Droks Trolls to see if things worked according to plan.
There are a lot of people that helped me, including some guildies and a random person i met in ToA. Hours of testing in Droks trolls and UW.
Ok now for the fun part. The builds...
Monk #1
Mo/Me
Level:20
Equipment: I wield a Rajazans Fervor, with +5 energy and 20% longer enchantments, this helps out a ton. My focus is a Ivor's Icon, i only use it for the +12 energy, so you can definitely find a better one.
Attributes:
Protection ( 9+1+1 )
Divine Favor ( 10+1 )
Illusion ( 7 )
Healing ( 10 )
Armor: YOU NEED THE LOWEST POSSIBLE AL! VERY IMPORTANT!
If you have the beginer armor with 5 AL, this is the best you can have, I use the canthan shepard armor, with 15 AL.
Headpiece: 15 AL prot headpiece with MINOR prot rune in it.
Legs: 15 AL shepard with MINOR divine favor rune in it.
Sandals: 15 AL shepard with major vigor rune in it.
Very imporant that you only have these 3 armors, so they will hit you for more, you will see why later. Why legs and sandals? For the +2 energy regen, of course.
Now what we've all been waiting for. The skills! ( or skillz ) heh.
Skills:
Spellbreaker {E}
Prot Spirit
Spirit Bond
Healing Breeze
Ancestors Visage (AV) or SV (The proph. altervative.)
Essence Bond
Balthazars Spirit
Rebirth
At begining cast the Essence Bond,Balthazars Spirit on yourself.
Then use {E}, prot spirit, and spirit bond, on yourself before you engage in battle, then keep recasting Spirit bond and prot spirit, you will NEVER run out of energy, or health. Trust me, and remember cast {E} when a nightmare pops up.
Ok, i know you're all wondering how this works. Heres a start, i have 536 health, and 37 energy. Now if you're a monk, you are confused if you're familiar to the skills listed above. And for you that or not, ill type them just for you.
Prot Spirit- For (-) seconds, target ally cannot lose more than 10% max life due to a single attack or spell.
Spirit Bond- For 8 seconds, whenever target ally takes more than 60 health from a single attack or spell, that ally is healed for (-) Health.
Now to explain. Since this obviously doesn't make sense. If i have 536 health, and prot spirit up, im taking 53 damage. Correct. That meens Spirit bond is not working since it requires 60 damage to be taken. Incorrect. Spirit Bond triggers BEFORE prot spirit does, that meens they hit me for what they would without prot spirit, usually about a 300. So i get healed for 84 health. BUT, since prot spirit IS up, they hit me for 53, and i get healed for 84. Therefore, im never dropping health, cause right when i get hit with anything, i get healed for even more. And the best thing, its instant, not waiting on regen to bring me back up like the 55, Right when i get hit, it automatically heals.
When you take on the grasping darknesses, you're gonna have to make a few changes. First of all, you're gonna have to change to your 55 armor, and you are gonna tell ur partner to drop a few enchantments, i'll tell you exactly what those are later on. Your breeze will have a +9 regen, and ur partner will have a +1 regen on u with succor, to start, so you are gonna just 55 for that part. After that, you're home free.
When you get to the smites, you can aggro ALL the smites you want. I held about 13-16 smites without even breaking a sweat. I meen, my health never dropped...ever. They died in about 8 seconds. It's simply CRAZY. Watch out for the coldfires, because they can be tough. I'll explain how to kill them later. Other than that, that's pretty much the holders job...I think i'll call this character the "Holder."
Now for the character i call the "Enchanter."
Monk #2
Mo/Me
Level: 20
Equipment + Armor: For armor, try to get the highest AL you can, but you need to have a Smiting headpeice with a Sup smiting rune, and a sup prot rune on ur armor. A divine favor rune is also recomended. Theres a staff thats perfect for this in the desert, located just outside of elona reach mission. He offers a 20/20 smiting staff req 9 smiting, for only 5 minotaur horns. Add a 20% longer enchantment on it, its great, no staff head needed, although a +5 energy head would be nice.
Attributes:
16 Smiting ( 12+3+1 )
15 Prot ( 12+3 )
Rest in Divine Favor
Now for the skills...im not making that lame joke again...

Shield of Judgement {E}
Blessed Signet
Arcane Echo
Rebirth
Vital Blessing
Holy Wrath
Succor
Retribution
Ok at the begining cast the 4 enchantments on the Holder. Putting him at 736 Health. Use blessed sig to get to 15 energy, have ur Holder cast Spellreaker, prot, then spirit bond, then cast SoJ on him. Have him go up the staircase and watch the Yellow numbers fly. ( Not to mention the -10's and -1's above yours. ) At the begining it should be hitting around 60+ from Holy Wrath + Retrib. and another 50+ from SoJ. Should be killed within 15 seconds. The enchanter can be WAY back, a full 2 or even 3 aggro circles away, so really no chance of you aggroing them. No need to wand down the nightmares either, since Spellbreaker should keep them from rending, and SoJ+Retrib+H.Wrath should kill them in 2-3 hits.
The aataxes and smites are VERY easy, but let's talk about the hard part. The dreaded Grasping Darknesses.
Ok since your Holder is changing to a 55 on this part, drop vital, retrib, and H.Wrath. This will leave succor on him, giving him a +1 regen. His breeze should be +9, so he should always have +10 regen. This part is pretty tough. Have the Holder cast Prot spirit, breeze, then aggro them. Also have the holder use SV or AV on himself to get the -3's flyin. At this point you should have arcane echo'ed SoJ on him, this should kill them with about 5 seconds left on SoJ if you time it right. You could also keep retrib on the Holder to get some -1's, and 2's.
__________________________________________________
Side Notes: On coldfire knights, the Enchanter will have to take off retrib and Holy and do a similar thing like he/she did on the Darknesses. The only difference is the Holder doesn't need to change armor, and the Enchanter should keep Vital up. Just make sure the Holder keeps SB {E}, prot spirit and breeze up. And when SB {E} runs out, use Spirit bond.
This duo uw build is pretty reliable since the Enchanter has a rebirth plus doesnt have to be right behind the 55 like the 55/SS builds. BOTH people have a rez so if by some chance the Enchanter does die, he's back up. Me and my partner killed every single smite, coldfire, and grasping darkness on that side of the map...very quickly. I don't have anything against the SS/55, i have done that, but this is just faster and safer.
When i did this, me and my partner were on TeamSpeak, and i was the Holder. If you have any questions, you can reply to this post or whisper me in game.
