After seeing many posts on here about Firelands trash farming, I decided to roam around Firelands to see if I could find anything different. Which I did.
Now before reading on, It Is strongly recommended (by my experience as a Mage) to use a click2port / fly & speed hack.
Located at the south most lava pool (Coords: 50, 80) are a total of three individual Fire Turtle Hatchlings (at the back) and a group of three Hatchlings (at the front) which have a 2-3% drop chance on ten man to drop epic items (including patterns) and a 6-8% on 25 man. These Npcs can be kited very easily by a range, they have: 1,000,000 health on ten man and 3,000,999 health on 25 man.
Located at the end of the north most lava stream (Coords are: 40, 27.9) will be a Ancient Lava Dweller.
The Ancient Lava Dweller has a drop chance of 8-10% (was 25%) on Chelley's Sterilized Scalpel and Spire of Scarlet Pain. (drop rate remains the same on 10&25 man).
This NPC' has a large health pool of 7,700,000 million which remains the same, even on 25 man and ten man.
The Ancient Lava Dweller will cast two spells, one of which is: Lava Shower which cannot be interrupted. However it only effects you if you're standing in his melee range.
The other spell is called: Lava Spit. Lava Spit doesn't do too much damage on It's own, however, after a while it will kill you. So if you aren't a Shaman it would be a smart idea to take one with you who has the glyph: Wind Shear.
This NPC' is very easy to kill, requires next to no skill and can still be killed by you alone duel boxing accounts with a shaman and another range character (you'll need to have Drakefish's KeySpam program running on your shaman and it will interrupt every single cast just by spamming Wind Shear as the NPC' only casts once per few seconds with a three second cast time.
You will however need to jump/fly down to loot. If you jump there is no way back up and you will most likely die if you cannot teleport out.
These methods are very useful as I've earned over 150,000 gold in the past week just by spending 8(ish) hours a day farming.
(I had bad luck as well with the drops).
