Delve modifiers[]
Some fossils can also add special Delve fossil-only modifiers, however, these modifiers are different from Delve drop-only modifiers from specific Delve nodes. Delve drop-only modifiers are drop-only while fossil-only modifiers are from fossil only. They both cannot be crafted from other sources. Lastly, the game developer, GGG, removed a large chunk of Delve fossil-only modifiers from the spawnable pool. Those legacy modifiers can only found from existing item which can be obtained from trading with other players in permanent leagues. GGG also added new influence modifiers that similar to the removed fossil-only modifiers, but not all removed Delve modifiers have similar influence modifiers.
