AC6’s IA-C01L Ephemera Legs
What mission? Underground Exploration – Abyss 1
Location: In this mission, you need to descend a shaft. While you float down, a partition wall will close off any further progress. However, that doesn’t matter, just look for a room in the wall. This is the only room in the shaft. Fly to it and find the chest in front of you.
AC6’s IA-C01B Gills Booster
What mission? Underground Exploration – Abyss 2
Location: After you fight Iguazu, you enter a cave. Follow the rail system until a door closes in front of you. In this room, there is a path on the right leading to another room. Defeat the two enemies and then open the chest in the new room.
AC6’s IA-C01A Ephemera Arms
What mission? Underground Exploration – Abyss 2
Location: After opening the first chest in Abyss 2, you will get the task to find a line of fans to turn the storm back on. Go back into the cave you came from and jump into the open empty area. In the fog, you will then find the crucial line.
Go through it, defeat the enemies, and let yourself be taken up by an elevator. You will have to fight again against enemies guarding your chest. Defeat them and collect your item.
AC6’s IA-C01F Ocellus FCS
What mission? Underground Exploration – Abyss 3

AC6’s IA-C01C Ephemera Core
What mission? Mission 3: Underground Exploration – Abyss 3
Location: You will find the core in the middle of the huge room. First defeat as many turrets as possible, as they can easily take you out. The middle platform has several struts. From the first box you picked up, look for the third strut and follow it to the end. There you’ll find the box.
AC6’s IA-C01H Ephemera Head
What mission? Surveying Unknown Area
