Coral weapon resistance?

[Sabaithal]

Has anyone done any testing to see if certain parts are actually resistant to coral based weaponry? From what I understand, it exists in its own catagory, independent of energy weapon damage/defense.

Also which bosses do we know for a fact use coral based weaponry? I'm guessing Ibis, sea spider, and maybe SOL-07/Ayre, just because their weaponry is red.

Based on what game actually shows to you - it is not an energy weapon, though i haven't tested whether energy engine does anything for coral weapons. Also there's no such stat as coral resistance in any armor piece.
It might be something like "true damage"

Coral is it's own damage type and is not affected by defense or generator EN spec.
That said it is still affected by OS tuning and can be increased by upgrading other damage type (Kinetic, energy, explosive) to a total of +15%
Need testing; very likely that SCA damage reduction still reduce coral damage too
