Final Impact Core: find the cave behind the rock
Final Impact Core is inside a cave in a large rock formation at a Zone 1 chest / LOOT location. Circle the rock instead of stopping at the chest, listen for the schematic cue and enter the cave. This layout is not restricted to the island immediately before the boss.

Follow these steps
Check the rock formation at a chest stop
At a Zone 1 chest / LOOT island, look around the large rock formation and listen for the nearby-schematic cue. The chest is the map landmark, while the schematic is a separate pickup away from it.
Open full-size image ↗Circle the formation rather than leaving after the chest. Circle the rock and enter the cave
Walk around the formation until you find the cave entrance shown here. Enter and collect Final Impact Core inside; opening the chest does not collect it.

Completion signal
Collect the schematic inside the rock cave. The chest reward is not the completion signal.
What the module does
Boosts the last round in a magazine.
If it does not work
If you only checked the chest-facing side of the rock, circle the formation. Do not discard a matching cave because it is not on the island before the boss: community directions identify the chest layout, not that single position.
