Cid proposes to build a better alembic for the chirurgeons, and asks you to acquire three ice sprite cores for it.
This quest is available if you have completed the quest Factual Folklore.
Starting the Quest
Talk to Cid in the upper floor of the northeastern building of Whitebrim Front in the Coerthas Central Highlands to begin the quest.
Slay Ice Sprites
Go down the stairs and go through the door on the left to go outside. Go south to the fire pit, then go southwest through the archway. You will see quest icons in the minimap showing where to find Ice Sprites. Kill them until you have three ice sprite cores.
Deliver the Cores
Go back into Whitebrim Front and go up the stairs north of the fire pit, and go into the northeast building. Turn right as soon as you go inside, to go up the stairs. Talk to Cid and hand over the ice sprite cores to complete the quest. There will be a cutscene.
Next Main Scenario Quest
After you complete the quest, you will need to be at least level 40 to proceed to the next quest. After you reach level 40, talk to Cid to accept the next quest: Influencing Inquisitors.
