Once you obtained all 5 parts of the recipe, you need to decrypt the recipe. Resident Evil advises to find Proper70 for that, he's an expert in this.
== Walkthrough ==
This quest will advance a bit down the story, when you'll speak to Resident Evil after Fenrir's stash and meet Proper70 in the scientist bunker in Jupiter.
=== First talk with Proper70 ===
Proper70 knows how to save Fenrir - for that you will need to obtain the recipe for a powerful flask, separated into 5 parts. Then you will need to obtain the decoder, Bubulyuka knows its location. Proper70 gives you a Teleport artifact so you can teleport to him.
After that, Anna addresses you. Speak to her.
=== Obtaining the decoder ===
WARNING: by advancing this quest further you can lock yourself out of an extra Ultra Artefact Detector. If you already did the Wanderer quest, make sure you also finished NS story (completing Bunker D-6 assault) and exchanged the detector as described in One-time offers#Yuri Semetsky. If you didn't start it yet, you're fine.
Go to Zaton and speak to Bubulyuka. He will tell you the location of the stash with the decoder, starting Searching for decoder.
After finding the cipher book and all 5 parts of the recipe, bring them to Proper70 to finish the quest. He instructs you to talk to Bubulyuka again, and gives you another Teleport artifact.
=== Decoding the recipe ===
Go and talk to Bubulyuka, exhausting his dialogue. In the end he will hint that you need to return to Proper70. Return to him, and discover that he decoded the recipe and that he has a final Teleport artifact for you.
