Fale is the collection quest giver in Aurora Village. There are six separate quests where he'll ask for some items from certain monsters.
Better than Nothing - 5 Imp Hides
Taking Point - 8 Beast Spears
Slimed - 4 Slimy Spikes & 4 Slimy Coats
Reinforcement - 2 Giant Rocks & 2 Giant Cores
Freedom of Movement - 6 Avee Wings & 6 Avee Claws
Find the Sparklies - 3 Florn Tentacles & 3 Florn Sparks
Once you've obtained at least one of any item, sell one to any merchant to catalog the item. When you do this, the shop will restock them over time, allowing you to purchase them instead of farming more monsters. As long as you're killing the majority of monsters, and cataloging any new materials you find, this achievement will come with ease.
All the monsters you need to kill for these items are conveniently located in Abadis Forest. This video will show you what each monster and monster drop look like. Click on a quest under "Fale Quests" to skip to it.
