Rule question for Godslayer weapon keywords

[Friend_Computer]

Heya! Had a quick question about the Godslayer's statblock. In the keywords, there isn't a value after Piercing. Should there be a set value or is it Piercing (Yes, screw your armor)?

Piercing (screw your armour) They're the best of the best!

Got it! Thank you for the clarification!
