i was thinking about this while fighting the ghost in st. fido. it would be amazing to be able to get a armor that makes us glow like the ghosts we have been fighting since the begining of the game! and to be able to change the colour from the dying shop in skull island! im sure this would be a very popular set!
thats a nice idea i didnt think about it :p but i think it would be cooler as a rare drop or a pack in the crown shop :P that way we dont get to walk arround and every pirate is glowing !
