Best place (or easiest) are HOT (halls of Testing)]
As you go out from zone in room take a Right at the round about.
Do not open the door without Asking in shout/ooc.
If people are fighting behind the door the door mobs will run in and assist if door opens (seen this and gets very ugly).
Once in casters set up in entry and will stay there (unless they need to cast then return) this will stop them getting hit by AEs.
This zone used to require a force to farm drops but can now be done with 1 good group. 2 good groups is much better of course though lol.
Any of the wurms can drop this stuff but mostly seen drops of the Ancient wurms.
Anyways happy hunting .
PS make sure you are over 55 and have very good Resist MR FR and CR. Buffed most of these should be at least over 150 Minimun or you will be AEd to death.
