As usual, in this guide I won't say anything about the story
. The spoilers are simply tips if don't want to spend time exploring/looking for something/somebody or understanding how to do the things by yourself.REQUIREMENTS
As you can see in the Codex, there are few requirements to start this quest.
First of all, you need to complete Vor's Prize and be at least Mastery Rank 1. After that, you need to complete a hunt in Cetus.
HOW TO START THE QUEST
Go to Cetus and speak to Konzu. Choose the option "A personal favor".SUGGESTIONS
The quest is really simple and the enemies are low-level (around 5). You can success in completing it also at the very beginning of the game (i.e. when you are at low Mastery Ranks and you have poor mods/weapons).
Just be sure to know how to use the codex scanner.
During the quest, you will go back and forth from the Orbiter many times. The evolution of the quest is straightforward and the quest itself will tell you what you need to do (just read what is written on the navigation system). Once in the Orbiter, to start a new step of the quest you can simply select it from the navigation (quest panel) and press A.REWARD
There are reports of a bug linked to this achievement. Once completed the quest, there are players who didn't have their achivement popped. All the achievements of the Plains of Eidolon can glitch. I have reports of guys having no trouble with the achievements, together with reports of random achievements glitching (one or more). It seems to affect people at random and actually it is not solved yet.
UPDATE: Digital Extremes is aware of these glitches and they will get a patch in the next future.
