Video http://files.filefront.com/ranger_uw.../fileinfo.html 34MB Echotrapper Build
I'm playing a while with a build that I use for soloing the UW, now I want to share it

The build is using Echo to lay multiple Dust Traps. It's possible to kill Bladed Aatxes, Grasping Darkness and Smites. You can almost clear the whole Underworld. I tried a few builds to solo the UW with my ranger but either it was damn slow or I just could solo one kind of monsters, this is the best for me because you can kill almost everything.
Some facts that might be interesting:
Bladed Aatxe's have permanent +3 life regen, you should always keep them bleeding, just to make sure that they don't self heal. Also they got a huge pool of health points. They're one of the hardest creatures you're faced with in the whole UW.
Grasping Darkness appear in smaller mobs. They move with 25% more speed compared to yours and like to interrupt your trapping. They're "just" level 24 and fast killed with some dust traps but don't underestimate them. They can still kill you behind the npcs, which you might use to hide.
Dying Nightmare's always pop up out or nowhere and just wand you with moderate kill speed. Their attacks might interrupt you through the effect of whirling defense. Don't waste traps on them, just kill them with your staff after you've killed the Aatxes and Darkness

Smite Crawler's are powerful healers AND smiters. They selfheal their group and kill you in one run. You'll find them in the Ice Wastes after you've taken the "Clear the Chamber" quest. They die on first contact with your traps, so better lure all you've aggroed into the traps.
At first the build:
R/Me
Wilderness Survival 12 + 1 +3
Expertise 12 +1
Beast Mastery 3 (+1 is optional but might be a good idea)
Echo (Elite)
Dust Trap - the main damage dealer
Barbed Trap - crippling and the -3 degen
Flame Trap - the burning effect and some damage
Whirling Defense - the only defense skill
Serpents Quickness - to support QZ
Energizing Wind - to reduce the energy
Quickening Zephyr - for faster recharge
Equipment:
- Superior Vigor (Major might be not enough)
- full druids/radiant armor is necessary
Weapons:
- a staff that gives you +20 energy and +30 (Insightful Staff of Fortitude with a "Hale and Hearty" inscription), something like this:
(I use a crafter staff from Camp Hojanu)
- a longbow/flatbow for luring (optional)
Base HP: 485
Base Energy: 53
How to trap?
One important point. Try to drop your traps near a wall or something because they don't flee that much and you can kill everything in one run.
1. Lay EW and QZ - You will be at nearly full energy when you got them up.
2. Now use Serpent's Quickness and don't make the mistake to echo it

3. Echo -> Dust Trap -> Echo of Dust Trap -> Barbed Trap -> Flame Trap (= one set).
4. Lay another full set after all traps have recharged.
5. Echo will expire and don't forget to use Serpent's again.
5. Lay Dust Trap, Bared Trap, Flame Trap. Don't care about the spirits, you don't need them anymore.
6. Echo has recharged. Lay one full set again.
This is always the same procedure, get used to it

After you layed your traps you should drop something (coin or a pile of glittering dust) to lure into the right spot.
How to lure
Don't waste much time and aggro. Use your staff or step into their aggro circle to lure them, it doesn't matter. Get Whirling Defense up when they're near, you can keep it up for just 18 secs. Now a very important step to make use of the full damage caused by your traps: don't stop at the exact spot where your traps are layed down, go a bit behind that spot:
(side view)
This works very well. Aatxes are directly dead even if they flee. It's also important to tank them if needed, because they always have to walk into the traps with the same distance or else one will be killed and the other one will chase you.
If your trapping fails nothing is lost. You got some nice NPCs you can hide behind, Renault saved my life a few times =) You can trap them to dead behind the npcs, it's absolutely no problem. Sometimes you'll need to kite and make use of the massive degen through flame trap and the crippling of Barbed Trap. Just practice a bit and it will be possible to clear (almost) the entire Underworld.
What to kill first?
At first clear The Hall with his Aatxes and Nightmares, then take the quest as usual. Kill the Grasping Darknesses and go to the Ice Wastes. You'll have to clear the other room which was locked before. Always try lure only one mob, e.g. don't aggro a Aatxe mob and Grasping Darkness' - this will mostly make you fail or make the run unnecessary hard.
Now you can enter the Ice Wastes. In this area it's very important to kite and not to aggro the Coldfire Nights. You got no healing skills and the Spells will slow you down and kill you in a few seconds. It depends on the spawn if you're able to kill all smites because the Coldfires will block a few ways but it doesn't matter, at this point you should have enough money to pay a new run

After this you can clear the Labyrinth or the Forgotten Vale - my inventory was already full at this point.
What nets you a run?
One ecto drops always and the drops aren't bad. My best run these days were 3 ectos, a black dye and 5p in drops and gold. Also you'll mostly see a Phantom Chest on your run.
I'll use this build again and again to get enough ectos for my FoW

Already explained by Eva

This is the next stage. You can lay 9 Dust traps (1170 pure damage from the dust traps!) instead of 7. It's more reliable because of the huge damage amount but you should be more careful with luring, always watch your health.
Thx to Eva for sharing.
