the first Swarm of pain is easy.
Talk to Gaudric Stormwind he's in a shack near the lighthouse.
>Hail, Gaudric Stormwynd
>What insect?
>Why do you want to mimic them?
First spell (lvl44):
You need 2 things 1=> a captured niflik ( no drop)
2=> a niflik ( look like a pouch) (no drop)
reward>> Spell: Swarm of pain (no drop) but MQable make sure the ranger give the last part
Second spell (lvl52):
Gauldric tell you he want an amulet dropping from a nadox follower
witch i believe is a troll in the crypt of nadox witch is i believe to far away in the tunel going up then once you reach the city go left following the wall untill you go up again. At the top of hill you'll see a castell witch i believe is the crypt of nadox. ( i'm saying i believe cause i'm not sure about that but look like it is ) nobody answered /ooc.
The mobs up there are DB and some yellow on track so i did not go much further without a group, could be fun to explore though
P.S. there is another quest for the map of the Gulf of Guntak=> you need to talk to a guy on dock of east freeport ( Cartomancer ) he give you a container to combine 3 items to make the map
1=>The compass rotation
2=>faded legend
3=>Coordinate level
These things are supose to drop on the Broken Skull Rock and Dulak harbor ( no clue where is dulak harbor
)
I got the second item drop from a troll on the beach .
Hope this has been of any help
If you need me just ask i can help.
