Drops for Darkforge quests in Feerott or CT?

[Broot]

Extunarian is correct, they drop in Cazic Thule on P99. Specifically, from 'a lizard man crusader'. They can spawn anywhere on the Avatar pyramid, and *perhaps* in the yard surrounding the pyramid.

They harm touch, have a pet, sometimes fear and are a general pain in the ass. Not to mention that the priest mobs (judicators, I think) will respawn as you clear lizards to make the crusader's pop, and they will heal through walls from a distance and they have a LOT of mana (but not agro, fortunately).
Even at 52 SK it was slow going alone - bring a friend or two if you are higher level, or bring an entire group if you are low level and want to make some exp out of it. I got a few levels there and most of my darkforge with a group of friends when I was the appropriate level. The healers slow down the exp a bit, but the zone has a good modifier and it is pretty easy to pull (group will have to move up and down the pyramid as they are clearing for a safe place to med, though.)

They can also spawn in the sewers.

One approach to finding them is using your "sense undead" spell since the Crusader's have skeleton pets. The spell will point you in the direction of the nearest one.

Good luck!
