Song - The Island (Part 1) (Crimsonik Remix) - Pendulum
I recently was searching around on to find some decent spots to farm Embersilk Cloth to level up my tailoring. I came across a couple of posts/people that said to head to The Restless Front located in Tol'Barad.
This video contains some killing of the mobs, which fight each other until they are at 19k health, and also have a high drop chance of Embersilk Cloth.
While farming there, I used a Potion of Treasure Finding, while wearing it you gain the chance of looting Tiny Treasure Chests which contain Embersilk, Volatiles, and gold. Gold is a guaranteed drop, while the other two just have a high drop chance.
Be sure to always wear the potion while farming.
Feel free to ask me questions.
