why isn't skellington's on the list? lol

That would undermind my ongoing attempt to get people to use Skellington less and go elsewhere.
I got 2 Mink Coat, 8 Saber(3), Cowardice Blade(2), Two-handed Swords(2), and various other equipment from Biolab 2 mobbing for an hour. Insert Blazers for more income and you perpetuate the game economy by providing to the Buy and Sell, rather than the Loot and NPC.
Magma 2 I get Abyss material, white herbs, Blazer Card/Rosary(1) if I'm lucky (got a Nightmare Terror).
Juperos I got a few Gunslinger weapons and and lots of cooking sets.
Anolians got me Oridecon at a good rate.
Got some Dead Branches and OBB from Ninetails, obviously killing the MVP as well.
Ice Dungeon. Cubics, nuff said.
Loli Ruri area has a large Gibbet farming area, get a bunch of Cursed Rubies.
Foot of the Sea Witch and Animal Gore from Medusa, obviously killing the MVP too.
I am perpetuating the market, not mindlessly creating zeny!!
