ok, so i don't know if anybody's said this already, but as of the .97 update, they removed all ore drops and magic powders drops

"Magic Powders have been removed from monster drops in preparation for the changes to the crafting system that is coming in the Chaos update this summer.
Currently, only the following ores drop from monsters: Dark Crystal Ore, Power Crystal Ore, Wisdom Crystal Ore, DEX Crystal Ore, LUK Crystal Ore."
