What about would this be?

[VoidGoji]

So, there is a gun in a ttrpg I'm playing. The gun doesn't exist yet (wasn't invented yet, the effect came before the cause), and its attacks simply deal damage. The damage bypasses any type of barriers, resistances, invulnerability, intangibility, can't be dodged and simply deals damage no matter what. There is paracausality/causality hax in the rpg, but dunno if this attack counts as that.
What ability (or abilities) would that be?

causality hax and resistance negation.
