Interactive maps & location tools

Choose the planet and mission node listed in the guide. Mission interiors use generated tiles; the navigation map locates the mission.

Visit Ergo Glast in a Relay and inspect the current weapon list and Holokey prices.
Choose a target that is currently available and note its displayed bonus.
Open Navigation and select a Void Storm in a Proxima region you can complete.
Finish the Railjack mission objectives and complete extraction.
Check mission rewards for Corrupted Holokeys; the reward is possible, not guaranteed every run.
Repeat suitable Void Storms until your balance meets the listed cost.
Return to Ergo Glast and recheck the rotation and bonus before purchasing.
Buy the target weapon while it remains available.

Ergo Glast’s selection and progenitor bonus rotate every four days, so verify immediately before purchase.
Holokeys are spent independently of Perrin Sequence standing; the vendor purchase uses the currency.

Repeatable as a reward-chance farm, but purchases are limited by the rotating inventory and each weapon is purchasable once per rotation.

Assuming every Void Storm awards Holokeys; inspect each result and continue if needed.
Farming toward a remembered weapon without checking the live stock; rotation changes can invalidate the target.
Ignoring the progenitor bonus; review it before spending the accumulated keys.

Stop farming once you can afford the chosen weapon and confirm it is still in Ergo Glast’s current stock.
