Obviously, still gonna go 55hp, as thats the easiest way to tank damage in the UW. Here's everything you need to set your elementalist up to get ready to go UW.
Equipment:
Stone's Eye w/any armor set (as long as they all have superior runes)
Weapon Set 1: Sword/Axe of Enchanting, -50hp Grim Cesta
Weapon Set 2: Galigord's Rod, -50hp Grim Cesta
note: Fiery Flame Spitter is a nice option for axe because the 10% receharge is nice. I personally use IDS for its looks
Attributes:
Energy Storage 5 + 3 = 8
Air Magic 2 + 3 = 5
Fire Magic 0 + 3 = 3
Water Magic 0 + 3 = 3
Earth Magic 12 + 3 + 1 = 16
Healing Prayers 9 + 0 = 9
Protection Prayers 8 + 0 = 8
Skill Set:
(1)Obsidian Flesh {elite}
(2)Protective Spirit
(3)Healing Breeze
(4)Crystal Wave
(5)Aftershock
(6)Essence Bond
(7)Balthazar's Spirit
(8)Mending
Ok now for the UW. When you first get UW, put all enchantments up (skills 6-8) and wait for energy regen. You should have max energy of 60 (unless you got HoD, in which case it would be 65).
Bladed Aatxes:
Make sure your 3 enchantments are up and you still have full energy. Now, get as close to the first set of aaxtes without setting the aggro. Get out weapon set #1, and cast skills 1-3 in numerical order. Once that is done, switch to weapon set #2 and pull the aatxes to you. When you get the aggro, wand down any dying nightmares that pop up (their Rend Enchantments will fail due to Obsidian Flesh). Now, once the nightmares are taken care of, switch back to weapon set #1. Now your ready to deal some damage. I usually get into a rhythm, 5-3-2--5-3-4-2. You must cast Aftershock and Crystal Wave almost as soon as they recharge in order to get quickest results. Obviously any order will work, but the key is to not use Aftershock and Crystal Wave back to back so taht u do not trigger AoE. If they flee, they will not be attacking you, and therefore depriving you of energy. Now groups of aaxtes are grueling because of their high health, but they are easily taken down with some persistance. (SoJ Mo/W may kill them faster, but they can't survive 2 nightmares, can they?
) Also, make sure as to not only fight just 1 aaxte, as energy will be a huge problem. Try to always pull solo aaxtes into another battle, even if it takes a lot of coaxing. Ok, finished the Aatxes? Moving on... Grasping Darkness:
So you cleared all the aatxes and you don't know what to do next? Talk to the Lost Soul and get the quest, Clearing the Chamber. 3 Groups of 4 Darknesses should pop up, all spread out. Get close to the first group, without aggroing, and cast spells 2+3 on yourself, switch to weapon set #2 to pull, and switch back to weapon set #1. Now, back up so there is no chance of any other groups of Darknesses aggroing. Groups of more than 5 cause big problems with the interupts (4 is hard enough as it is). Once your in the right place, renew your enchantments and start using your damage dealing spells. I usually avoid getting into a rhythm here, because you really have to be careful of interrupts. Protective Spirit is not in danger, but Healing Breeze is. If it gets interupted, do not panic. Just calmly wait the 2 second recharge, and re-cast. You shouldn't die in that short timespan. If they get you with a Skull Crack, things get a little bit more complicated. Healing Breeze then has a 2 second cast, making it very hard to use. Yet, Protective Spirit is still going to be on at all times, and you should be able to survive the duration of being dazed. I would say that darknesses are the hardest part to deal with, considering interupts. But, when you start doing your damaging spells, you'll be relieved that they drop twice as fast as aatxes. Note: you do not need Healing Breeze for 1 or 2 darknesses.
Smite Crawlers:
Now for the easiest part of the run. Most builds, SoJ, SS, IW, have a problem with Smites becuase of Reversal of Fortune. But that's where the E/Mo solo outshines the rest of solo UW builds. Use the same pulling techniques as shown above with aatxes and darknesses. Now, try and get into a casting rhythm again, and now you don't have to worry about any interupts. The reason E/Mo doesn't have a problem with smites, is that Crystal Wave ignores magical resistance, meaning it goes right through Reversal of Fortune, Divine Intervention, etc. Aftershock will still be affected by RoF and DI, but still use it as it will still do some damage. Hopefully, you will be able to drop all the smites at similar times. You do not want to be stuck with 1 smite left, with 50% health. If this happens, try to pull other smites, or you will have to try finish him off. Note: you do not need Healing Breeze for 1 or 2 smites.
Coldfire Nights:
Try to avoid these at all costs. They don't drop your ectoplasms, so why kill them? If they are in the way of some smites, then killing them may be your only option. But i warn you, your success rate againt them is not high. The best way to beat them would be keeping Obsidian Flesh for as long as possible, and hoping they dont get a Maelstrom of in the downtime. If they do, make sure to move out of it to cast, before moving back close to do your PBAoE spells for the kill.
Ok, now that you've finished your run, go back to Temple of Ages and sell your ectos! I know this build isn't as fast as some other solo UW builds, but it is definately safer in my book. You obviously need patience and persistence to work this build out, but when you get it down, its really fun.
Tried the solo run, but want to go back to 2man runs? Well no problem! Keep the same attributes and equipment. The only adjustment you need to make is switch out the 2 damage dealing spells (4 and 5) and put in Aura of Restoration, and Whirlwind. Aura of Restoration basically replaces Divine Favor that the monks get, therefore granting you more health everytime you cast. I personnaly use Whirlwind to knockdown all adjacent foes, giving me a window to cast Healing Breeze without interupt, thus allowing you to aggro bigger groups.
Well I hope the build helps all you elementalists out there that are bored of echo nuking in Sorrows Furnace. Come out and try this build, the total cost of it is only around 5-10k (cheaper runes, ascalon armor, cheaper wand). Thanks for your time, and goodluck! Any questions PM me, IGN->
