how do you flavor your weapons
in the blood of my enemies, obviously.

seriously i think the only reflavoring of equipment i've done, specifically, is that I replaced a clerics shield with an old school censor. essentially they carried around an incense burner on a chain that they could light as an action. the smoke combined with some handwavy divine magic mumbo-jumbo is what caused the +2 to AC. obviously the censor also functioned as their holy symbol.
