how to use for TOPK?(can be used on NM and HM)
you can only farm level 1 and 2 with it but there are good drops there to.
back up to the wall when you enter TOPK
target the grasping darkness, use shadow of haste and run to them, when you come close, but not in earshot use glyph of elemental power and shadow form
use deaths charge to teleport there
use sliver amor use obsidian flame and tenai's crystal to help sliver amor kill enemys
when shadow form is about to end use dark escape, witch will teleport you away from them. because: shadow of haste is a stance, so is dark escape, and you can't have 2 stances active at a time, this means, shadow of haste will end and teleport you to the place you used it, becuase you are that far away the enemy will not follow you, and you can keep repeating it.

counters : you cannot kill the wurms in lvl 2

FoW :
FoW is yet untested but you can farm parts of it
it is the same way as in topk, olny in the beginning of FoW there are enemys on each side witch is hard to find a safe starting place

UW :
is allso still being tested but :
stand on he edge of the cliff, use shadow of haste and take the quest"clear the chamber" and use dark escape to tele away
you'll have to kill the kaaing axes first, if there are to less enemys they cannot be killed, when they are dead go for the others

there is a green item build that is allmost the same :
attributes are the same
skills :

glyph of elemental power(no attribute)
shadow form(shadow arts)
death's charge(shadow arts)
sliver armor(earth magic)
stone daggers(earth magic)or obsidian flame
crystal wave'earth magic)
tenai's crystals(earth magic)
dark escape(shadow arts)

with this build you can farm many green items but not all of them

The same build can be used as A/E, with 16 Shadow Arts and 12 Earth Magic. You deal slightly less damage with each skill but Shadow Form lasts slightly longer, so you can attack for slightly longer.

I am curious why health a minimum of 400? If you have Shadow Form up, you do not take damage from most sources - only signets, AoE that is not targeted on you and touch skills. I have not seen any signets or touch attacks in Tombs, and the only time AoE has been a problem was when I was dualing these builds with Frizz and we attacked the same group of terrorwebs - that way there was more than one target so the AoE got through to the non-target.  

The only mistake you can really make whilst fighting is in UW, cause if I recall correctly the aataxes use deadly riposte (which also goes through shadow form). So don't physically attack them, just use your spells. This is more a problem for A/E than for E/A I believe (does deadly riposte work on staffs? I forgot)
