Unlock requirements are rarely stated plainly in-game, which is why how to unlock a locked pdf gets searched so often. Below is the actual condition, plus the fastest way to satisfy it.
The difference between a smooth run and a frustrating one usually comes down to preparation, not skill. If you are short on time, the first section alone is usually enough. The community figured most of this out through repetition, and the pattern has held up well.
The short answer
The unlock fires on a specific condition rather than on progress in general, so aim directly at that condition instead of playing more.
What the requirement actually is
There is a fast way and a safe way, and they are not the same thing. The approach below has been checked against the current version rather than a patch from two years ago. If the item is account-wide, you only need to do this once ever. The community figured most of this out through repetition, and the pattern has held up well.
Some conditions only evaluate when you return to a hub area, which makes them look broken. Give the first attempt an honest try before deciding the method does not work. Start with the simplest option before touching anything that is hard to reverse.
The quickest way to meet it
Small details matter more than they should here, so read the order of steps carefully. If you are short on time, the first section alone is usually enough. One clean run beats five rushed ones, both for results and for your patience.
- Check the version you are running before following any step-by-step advice.
- Back up your save if the game gives you the option.
- Write down what you changed, so you can undo it if the result gets worse.
- Do the condition in a single uninterrupted run if the counter is hidden.
- Restart fully after a change rather than trusting a quick reload.
- Keep a spare loadout for the attempts that go badly.
How to tell it worked
The community figured most of this out through repetition, and the pattern has held up well. Give the first attempt an honest try before deciding the method does not work. People often blame the game when the actual cause is a setting they changed weeks ago. Some conditions only evaluate when you return to a hub area, which makes them look broken.
Most advice on this topic assumes you already know half the answer, which is exactly the problem. Small details matter more than they should here, so read the order of steps carefully. If something here stops matching what you see on screen, the game has probably changed a value in an update.
Mistakes worth avoiding
- Skipping the preparation step because it looks boring, then repeating the hard part four times.
- Following a guide written for an older version and assuming nothing moved.
- Trusting a video thumbnail over the actual patch notes.
- Changing several settings at once, then having no idea which one helped.
