Well, I didn't know that pre coming here. But I heard this was the suggestion corner, not the stomp on hopes corner.
Adding in the plume wouldn't break the game.
Also repeated a lot:
Before you post something, search the forum for suggestions similar to your idea. Loads of roman and greek shit has been posted already, and no it doesnt break the game, but this is a medieval rpg and they wanna keep it like that. Adding equipment that doesnt fit that wont be added.
Im not stomping on hopes, im just saying it before you put a lot of time in it, get your hopes up and then get to hear it wont be added.
