Tathlum isn't specifically made to deal with Crom Cruach.

I have that idea of a weapon needed to defeat Crom Cruach because base on his mythology, he was defeated by St. Patrick.

Ishibumi might go in that direction or maybe not. But since we don't know anything what's gonna happen, we can only speculate by using related topics about them since Ishibumi is more prone to use materials from their mythology than creating a whole new way that is far different.
