The issue with these 2 bugs is that any kit can get the trident using it. The easier model is in the lobby of Gondor. You throw the trident of the Pelargir seafarer. Before it returns you switch class and the trident still returns. You can do it multiple times so its how quick you can throw and switch class which limits you. Another theory that im not to sure on is that if the trident is thrown when the seafarer dies in combat. The trident drops for anyone to pick up.
