How exactly are the materials for this skill, other than the herbs, be obtained?
Mining? Monster hunting?
(Would ask the same in the Engineering thing but I'll take one thing at a time)
With the Sulien Ecology skill.
In the Sulien Ecological Reserve, there are these gathering spots that look like... glowing magical things.
Gathering from them gives things like "sulien" that's used in crafting some of the Magic Crafting items, as well as herbs sometimes.
Other things like Mutant Rabbit Foot and stuff are obtained from killing the creatures that are in the ecological reserve area, like rabbits and plants and sasquatches .
Stuff for Engineering is found in the Heulwyn(?) Mines. Ores and stuff from Drilling the crystals there, and other things from the monsters that are in the mines.
The ecology place is in Connous, and the mines are in Physis.
