A/e Obsidian Shards farming guide

Sorry if this has already been posted but i did not see it anywhere so here goes:

[Obsidian shards a/e assassin;OwZToY/85R6zj0ZtTkxND31ABA]
Attributes:
16 shadow arts
12 fire magic
3 deadly arts

Weapon: Droknars fire staff i use or any req 9 fire magic staff with enchantments last 20% longer and +5 energy at least, i only have 51 energy.

Usage:

Ok enter FOW using 1k or a fissure of woe scroll, you will now see a group of elementals, a warrior, mesmer and a necromancer, here is how you kill these:

You need to wait for the patrol of 2 elementals then move around till the elementals+mesmer group tightly like so:


Then use your attack chain:
Frigid armor->glyph of lesser energy->burning speed[wait 5 seconds]->Burning speed[wait 5 seconds]->burning speed[wait 5 seconds]->burning
speed->glyph of swiftness->deadly paradox->shadow form->frigid armor->glyph of lesser energy->burning speed[wait 5 seconds]->burning speed(they should then be dead).

Next we head towards the beach which i am quite sure people know where is but if not it is this way:


Switch the groups so that they run your way let those 3 patrols get away then head towards the first group of snarling driftwoods and then take the following patrol with that first group of driftwoods as shown here:


Continue on through the beach killing the last 3 groups of snarling driftwoods(should be able to get all 3 groups in 1 pull).

Then you should head through the spider cave this way

Once through the spider cave head this way:


Head forwards from there and use burning speed till your safe near the first infernal wurm near the abyssals and then pull the following 3 groups:


You should then have 12 abyssals and about 6 mesmers on you, group up the mesmers and get next to them and use your attack chain again till they are dead.

Then head this way through the lava(doesn't burn you)


Aggro 2 groups of abyssals and mesmers-> 8 abyssals and 4 mesmers group them up and kill them with attack chain.

Then head this way
towards the bone skeletals.

Careful do not get next to the ice elemental skeletals as they will roflmaopwnedcheatshax you with their touching skill which goes through shadow form ouch! just get into a empty space and lure as many skeletal berserkers as possible, first group i have managed to get this many:

Kill them with your attack chain, by the way the monks will use infuse health on as many berserkers as monks their are say 4 infuse on 4 berserkers :P leave them alive and run towards the next groups kill the last 6-8 berserkers and your run is over.

Congratulations you have completed of the best shards runs for a permament-assassin best shards i have gotten was 12 shards but that was complete luck you usually range 1-10, i hope you have many fow runs and ty.
