With The Great Expedition event, a new Fishing Rod was added to the game: the Mariner's Fishing Rod.
Its description says: This legendary fishing rod is said to have caught a giant creature from the darkest of depths once, strong enough to even reel the ancient being in.
I would like to know what differentiates the Mariner's Fishing Rod from a regular Fishing Rod. Is it easier to catch fish using it? Or is it actually possible to catch something other than the common fish?
