/cry seee this is why I never get to do these anymore. Everyone loves to do them.
Welp... As advice on paper (ie. the hard one) there are four spawn points on the first level of the Necropolis (main entrance that is.. in the southern most part of Batilla downs, by the island). Each one has two Lich spawns, and you can just run from spot to spot, but expect random agro. I think the funniest death was when we were just outside of agro range of two lichs and Skeletal Warriars when the lv50 rdm converted... I had about enough time to say "Nooooo" when the blood agro brought them all on us, just as an earth elemental passed by. Ooooo.. good times >^.^<m
Anyway, these camps are crouded at times, and have lotsa agro oportunities. However, the "hume bones" camp supports four lich spawns, as well as a good spot for taz. bell and coffer keys. This just takes a switch and a drop down a hole. The best spot for paper, in my kitty opinion, is the Necropolis entrance from the Glacier. There are at least 8 spawn points that I can think of there alone (and one coffer spawn). You can get up there via Teleport Valtz and then trek down, or just run through Rangemont Pass (my personal favorite.. I just.. HAVE to get a spelunking hat! I have to!). Best run is to have someone who does not get agro to pull lichs to the camp at the entrance, since they dont link.
Oh.. I dont know if its true or not..but they seem to drop the worse on Darksday, but that may just have been bad moons.
Anyways... the mold is just a question of killing enough Exorays..and theres a TON of them mushrooms in the nest waiting to meet alice. And the bomb coal is the eaaasiest of all drops, to the point where I just normally solo them and let the people who need it wait at the gate. If I bring back any doomed flesh afterward is purly coincidental.
