    Clear all the Eridian Proving Grounds.

  • How to unlock 100-Proof

    There are a total of six Eridian Proving Grounds in the game. The first step is unlocking/discovering them all. They first become available late in the story when you complete the 'The Great Vault' main mission. At the end of this quest you'll get a prompt telling you that the Proving Grounds can now be accessed. At this point, six side quest markers have now been added to maps where each trial can be discovered. Simply fast travel to each map and pick up the trial side quest from the little pillars where they are. The zones they can be found in are:
     
    • Pandora, Devil's Razor
    • Pandora, The Splinterlands
    • Promethea, Meridian Outskirts
    • Eden-6, Floodmoor Basin
    • Eden-6, Jakobs Estate
    • Nekrotafeyo, Desolation's Edge
    Once collected, navigate to each trial's location by using the navigator on Sanctuary. Each trial works the same way: you have 25 minutes to clear out three or four rooms of enemies, and then the last room contains a boss fight. The boss always has two health bars. Once you deplete the first, it regenerates a second. After defeating the boss, the trial ends.

    In general, these are markedly easier than the Circles of Slaughter and should pose very little problems even playing solo. The bosses are the only real threat, but all areas tend to have decent cover to hide behind, as well as a few normal enemies that can easily be picked off if you get downed. Once you complete all six, this achievement will unlock.

  • After finding a Trial quest marker, you must always return to Sanctuary and put in the coordinates on the command bridge. Then you'll be transported to where the trial takes place and exit through the drop pod in the cargo hold, kind of like whenever you went to a new planet during the main quests. All Locations: *Pandora - Devil's Razor - Gradient of Dawn (Trial of Survival) *Pandora - The Splinterlands - Ghostlight Beacon (Trial of Cunning) *Promethea - Meridian Outskirts - Precipice Anchor (Trial of Discipline) *Eden-6 - Floodmoor Basin - Wayward Tether (Trial of Instinct) *Eden-6 - Jakobs Estate - The Skydrowned Pulpit (Trial of Fervor) *Nekrotafeyo - Desolation's Edge - The Hall Obsidian (Trial of Supremacy) **original post by Purlinka on the Playstation version of this tr
  • Thanks for the info #1!
  • Has anyone have this trophy glitch on them? I've completed all 6 of those proving grounds multiple times. I have the trophy for completing all side questions but this one is still locked.
