My new N/Me UW Smite run build.
 

Ok this build is for Underworld 2 or 3 man Smite runs.
It is designed to kill any mob in UW as fast as possible with no downtime between mobs. And it works.
20 N/Me
Arcane Echo
Spiteful Spirit
Insdious Parasite
Suffering
Desecrate Enchantments
Res Sig
Awaken the Blood
Blood Ritual

16 Curses
12 Blood
6 Soul Reap

Note: Keep Awaken the Blood active all the time for extra damage, however it isnt required. Just speeds up kills.

This build vs Bladed Aatxes:
Wait for the monk to get agro, then use Arcane Echo, Spiteful Spirit and get Spiteful on as many targets as possible. When there is just one Bladed left, also cast insidious parasite to kill it faster.
average lifespan about 30-45 seconds

Vs Grasping Darkness:
Same thing as above cept they die 3 times as fast.
average lifespan about 15 seconds

Vs Smite Crawlers:
Ok this one is the trickier mob to fight because of smite hex. Start off with Spiteful and as soon as you finish casting - cast Suffering on same target and then desecrate enchantments. Make sure you always follow spiteful with suffering, which means you must have around 27 energy when you start to cast Spiteful. Clean up the remaining Smites with desecrate enchantments.
average lifespan about 30 seconds

Vs Coldfire Nights:
Tell the monk to keep moving around til there all in melee, if the monk doesnt they just stay in ranged mode. After they are all close to each other, arcane echo spiteful spirit and a random desecrate enchantments thrown in.
average lifespan about 40 seconds

After each group of monsters always cast Blood Ritual on the Monk to speed up the downtime.

Feel free to try it out and post your comments.

Is it really worth it engaging Coldfires? We usually avoid them as killing all 3 in the group is tricky and sometimes leads to our deaths. We've got the pattern down of their patrols....I'm gonna try this on them and let you know how it works! BTW---great job on the UW build...this I gotta try!

i run a similar build if i run 2 man in UW. an average run is 15-20 mins, excluding coldfires as the drops they give are just pathetic. once you get spiteful on the aatxes they will wear down fast. get you monk to agro all aaxtes as i get mine too.stand down below by the guy you get quest from and cast spiteful on atleast 2 of them, every recharge cast it on another, this combined with suffering and disease allows 8 aatxes to be dead in around 25-30 seconds. from there the run is basically over, as the smites pose no problem at all. get your imonk to agro around 15-20 smites then just huddle in bonettis, cast spiteful spirit first!!!!!! not suffering, cast spiteful first and then suffering straight after on same target. usually only takes 1 cast to fully kill all smites attacking. very fast and efficient build, been running it 2 man for around 4 months, also modified it to run it solo in UW with n/mo. average run 20 mins as opposed to 10-15 for 2man. well worth it. buying my 6th and final set of fissure when we get favor today. :)

Very nice, thanks for the tips I will make the changes on the above post.
