Best Chirl Crystal Form – Death Stranding 2: On the beach

In the early days of the game, you will be asked to bring back the North of F1 online immediately after fighting the first boss in Australia. This will be during the main order 13: restore the monorail and distribute special alloys to F1. When you reach the mine, you will find that this tar is surrounded by pits, and they are filled with Tar pit chirl crystals.

You can find some small creatures that are running around the place that looks like small spiders. To deal with them, walk close to them and when they start chasing you, throw a blood grenade back. Keep supporting, and they will all try to follow you, run and die in blood grenade. After that, you are free to head in tar and hold the crystal. You should be safe enough in tar; Just avoid deep areas, and do not stop moving into it.
The best way to cultivate chirl crystal is to slowly play the game while playing normally. There are plenty of ways to get them, such as pulling from storage in features, and you get access to more number of them because you rank the feature by distributing items. As soon as you distribute the items, you will find them on all the ground too, so make sure you hold something on your journey. Showering will also give some yield, as they can be obtained from Sam’s physical waste, and you will be surprised how much you can get by doing so.
