DREDGE - Blackstone Key

The sigil is moderately useful because it *slightly* increases your chance to pull aberrant fish. The engine is a slower, inferior version of a regular one you can buy after like an hour of playing but it gets slightly faster temporarily if you lose sanity. That's it. This pack is not worth $5 on its own but if you want these items it's a better deal to just grab the deluxe edition.

I played the game fully, 100% the game, nothing left to do except do it all over again. Knowing everything now, I find these items disappointing but since the game is easily worth the price to have it complete, not a big deal. Someone already stated what they do in their review. The one item seems it might help attract the bad too but I'm still not sure. The important thing is to know you didn't get shafted on these items, that you must go dock at Blackstone Isle to grab this DLC from the shed there. You don't need to wait until that certain point in the story to get them either. I forgot at first on my replay and was unhappy I didn't have my stuff when doing a new game in another save slot but then I remembered the shed (which is locked if you don't own the DLC).

This DLC is worth $2 max, even that's a stretch. You get an engine that is irrelevant the second you get it, with the gimmick that it gets slightly faster the lower your sanity gets. The charm you get increases your chances of getting aberrant species of fish by a miniscule amount.

Its a nice little bonus but absolutely not worth $5, save your dollars

You'll get use out of the engine for less than an hour and immediately replace it the charm has a terrible description of what it actually does and never used it since there's nothing noticeable changed to fishing with it
