Metal Strongbox guide
A Rare find in Tidefall, the Metal Strongbox is less a fish than a salvaged crate, described as a heavy-duty box lost from some underground civilisation. It is attracted by a Magnet used as bait, which is a strong hint about what it is.
Every one weighs exactly 30 kg, since the minimum, average and maximum are all the same value. That makes it predictable: at C$25 per kg you always get C$750, 355th of the 742 documented fish by average value. Its weight ranks 358th of 663 fish with a documented maximum, and it gives 200 base XP.
The only other Rare fish in the same zone is the Giant Grouper, and the rod sold in Tidefall is the Fallen Rod, so those are the names to keep in mind when you plan a session there.
The practical value is reliability. There is no luck involved in how much it pays, so you can calculate your return before you cast. If you need a fixed amount of C$ and have Magnet bait, it is a sensible catch. If you want a big payoff, it is not that. Treat it as steady, unspectacular income and move on to the next cast.
