Cloudkill in a bottle
From Ancient Anguish Mud Wiki - AAwiki
First, go to Ilderia and find the Song mage.
Say "history" or "story" and you will be sucked away into a dream.
Watch and learn until you see a death knight waving an axe.
"Take axe" to get the bronze axe. "Wake" from the dream.
Go n, w, n, to the wicked-looking tree and drop the axe.
Next, run up to the gnollish temple by steading.
Kill the guard or any other gnoll in this place, and bring the corpse back to Ilderia.
Drop the corpse at the wicked tree, take the axe, wield it, cut the tree.
A deathwraith will be spawned.
Kill the deathwraith. When you kill it, type "capture cloud" with an empty bottle in your inventory.
Leave the axe here if you want to do it again, since you can't bring axes into Ilderia.
The Ilderian cloudkill is a thrown weapon and you'll need a lot to CK an NPC.
