In Curse of Osiris, players are introduced to the Infinite Forge, a place where they can use Lost Prophecy tablets to create new weapons. Before any weapons can be created, there are a few resources that must be collected, and one of the most common ones is the Concentrated Radiolarian Culture.
How to Get Concentrated Radiolarian Culture
The Concentrated Radiolarian Culture is the easiest material to collect out of all the necessary resources for use with the Lost Prophecy tablets. The only way to get Concentrated Radiolarian Culture is by completing Public Events and opening chests on planets. At the end of a Public Event, you will have a chance of getting a Concentrated Radiolarian Culture, so it’s a good idea to farm Public Events – and even Heroic Public Events – with other people. You might also need to farm for Fossilized Hermaion Blossom and Advanced Paradox Amplifiers.
If you manage to get 10 Radiolarian Cultures, you can take them to Brother Vance and trade them for 1 Concentrated Radiolarian Culture. You will want to get as many Concentrated Radiolarian Cultures as possible, as there are six Lost Prophecy Tablet guns that require the rare resource:
- Garden Progeny 1, Scout Rifle
- The Conqueror 2, SMG
- Jack Queen King 3, Hand Cannon
- Machina Dei 4, Pulse Rifle
- Sol Pariah 6, SMG
- Null Calamity 9, Auto Rifle
To craft all of the Lost Prophecy guns at the Infinite Forge, you will need to collect 11 Concentrated Radiolarian Cultures throughout your playtime. Unfortunately, there is no way to guarantee yourself an Concentrated Radiolarian Culture, you will just need to play more and keep grinding for those drops.
