Mythril Crate

The Enchanted Sundial is the pull. Skipping straight to the next dawn sounds minor until you are waiting out a Blood Moon or trying to cycle Angler quests, and it is the only thing in the pool that changes your world instead of your inventory. Everything else here you could live without.

The Falcon Blade, Beguiling Lyre and Ginger Beard exist nowhere outside this crate and its pre-Hardmode version. None of them is going to define a build at this point, but if you are chasing a complete item collection there is no alternative source. Sailfish Boots and Tsunami in a Bottle are the accessories actually worth keeping, since both feed crafting chains you will finish eventually.

The metal lines all compete against each other. One roll decides whether you get ore or bars and which tier, so a crate never pays out both at once. It does always hand over something from the upper part of the table, which means these are never completely blank, just often boring.
