How to farm

Before you go

Unlock Railjack and access Proxima Void Storm missions.
Check Ergo Glast’s current Tenet melee and speargun rotation.
Choose a weapon and confirm its progenitor bonus before farming toward it.

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.

Farming tips

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.

Repeat, collect and use

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

Common mistakes

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.
