Black heraldic armour set 1 (sk) is made by exchanging all the components of a set of Black heraldic armour set 1 (sk) armour (except platelegs) with a Grand Exchange clerk. Players can then exchange the set with a Grand Exchange clerk to receive the items individual items. The set is purely to save space and for use in the Grand Exchange. It is made with, or can be exchanged for, a Black helm (h1), a Black platebody (h1), Black plateskirt (h1) and a Black shield (h1).
This armour is normally used for decorative purposes, as normal black armour has the same stats and is cheaper.
