I am done with the game for now and now I collect every horn I can find for ships. But, I accidentally sold the crimson horn that you get at the beginning of the game and tempest bolt that you get during "Unfinished Business" and I have both of them one on my other character and I want to trade it between my characters. But, it says no trade on the crimson fog horn and tempest horn and could you possibly change it to no auction only. So, if you would like to trade them between characters you could.
