this build can effectively run both orosen and ghial in one outing and takes about 5 minutes per run.
stats:
Earth Magic 12
Shadow Arts 12 + 1 + 3
Armor:
shrouded with shadow arts mask, superior shadow arts and as many atunement runes you think you need. personaly i think just the armor and weapons do fine
Weapons:
there are a few posibilities here, my favorite is
Totem Axe + Stone Scroll that can be obtained from Ohtah (just outside visnuh square) for 5 plague idols. [stats: energy +12 (req 9 earth magic), earth magic +1 20%, health +30)
Also galigorgs stone staff or scroll with totem axe work well
the essentials are 20% enchant and high energy.
The skills are as follows
Shadow Form {Elite}
Deaths Charge
Glyph of Concentration (this can be swapped for Glyph of Elemental Power if you feel it unnescisary. personaly i find the amount of mesmers faced requires it)
Sliver Armor
Obsidion Flame (can be swapped for shock if prefered, however i find it helpful in removing orosen before he can heal himself and sliver armor runs out)
Aftershock (good for if you use shock, also just a good overall damage spell to ad on to the speed of killing)
Feigned neutrality
Dark Escape
ok first off (im asuming you know the rout to take)
run to orosen before he leaves his spawn location.
just before you agro him, activate feigned neutrality.
with feigned neutratily up, run past him and his squad to the next group of 4-6 jade brotherhood. pick them up in your agro. now time to hit shadow form
once shadow form is up, use deaths charge on orosen, imideately followed by the glyph of concentration and sliver armor. its also nice to throw down your obsideon flame here because you cant be interupted. after those go off, fire off your aftershock and then another obsideon flame. if all has been done well, even with his heals orosen should be dead, rechargin all your skills. fire off another shadow form, grab his green (hopefully) and fire up your dark escape. run across the bridge, breaking the agro and wait there. shadow form will run out, and youll be left with a little bit of health, but put up feigned neutrality and get it back real quick. then comence your run to ghial. first use dark escape, then feigned neutrality shortly after to run past the 3 groups before you get to the small camp of friendlies. keep running to ghail.
at ghial you will have to bring a few people back in to attack him some more as you did with orosen, so activate feigned neutrality and run closer to ghial, bringing 6 or so people with you. once you get close, use shadow form and then deaths charge to ghial, followed by glyph of concentration, sliver armor and then the other 2 kill spells if you want. when you get to ghial, after youve used sliver armor, you might want to put up another feigned neutrality to watch the carnege and make sure you dont die as your precious ghials staff works its way out of its owners hands and into your own.
hope you enjoy the build
