Triggering an observer stash:
- Use an Arkhe with a Syn-tec scanner, and have an alt with a bot nearby. When the Arkhe dies, your alt can pick up the loot (note that you need to do the scans first, since every agent has their own list artifacts he's able to find).
- Have a teleporter spun up and ready to go.
- Use a heavy shielded Sequer (fitted with a small shield generator, 2 shield hardeners and a small energy injector).
