In a way that relates to the system of symbols and designs used to identify individuals or families, especially in coats of arms.
The coat of arms was designed heraldically, following all the traditional rules.
Heraldically → It is formed from "herald" (from Old French *heraut*, meaning a messenger or one who proclaims) and "-ically" (a suffix used to form adverbs meaning in a manner relating to). The word "heraldically" refers to something done in the manner of a herald, particularly in relation to coats of arms and heraldry.
Think of a 'herald' as a messenger who 'proclaims' information, and remember that 'heraldically' means doing something in the manner of a herald.
