Best Carcosan modifiers in Saros

Carcosan modifiers in Saros are unique buffs and debuffs that you can equip to upgrade Arjun’s abilities and traits. You’ll unlock the system after you complete the second biome, and can access it by talking to Primary in the Passage. Depending on the list of modifiers you put together, you can turn Arjun into the best soldier against lovecraftian creatures, or you can make the game unbearably difficult.
