Proboscis Cernos doesn't count as a Cernos in the Deep Archimedia individual parameters.

Basically the title.

So far, the names in Deep Archimedia work exactly like Riven families - Proboscis Cernos is it's own thing and doesn't take Cernos rivens, so this is the expected (although rather unintuitive) behaviour.

 

The same will apply to the Multalist Cernos, which is again its own Riven family (likewise Dragon & Dex Nikanas and a few other cases I forget).

That's not a bug, both the Mutalist and the Proboscis Cernos are different weapons, these are not Cernos variant like the Prime or the Rakta.
