Due to the fact players will likely have several remaining keys even after unlocking every single locked chest in the dungeon, the Lock Box can prove useful for obtaining more loot, especially if there was a dungeon-exclusive item that did not spawn in a player's world.
Despite the Golden Lock Box being a way to renewably obtain loot that would normally only generate randomly in the Dungeon, thus being similar to many other kinds of fishing crates, and despite the crates which contain it also containing Books (on Desktop, Console, Mobile, and Switch), neither the Dungeon Crate, Stockade Crate, nor Golden Lock Box contain the Bone Welder.
On tModLoader, this item may be particularly hard to obtain, as it is only obtainable from a Dungeon Crate, which can only be received from fishing in the Dungeon. Water may not naturally generate in the Dungeon.
Tips[]
On the special seed 05162020, players can obtain Dungeon and Shadow Chest gear pre-Skeletron by opening Golden Lock Boxes.
If the player does not have high defense or a Cobalt Shield, they may have trouble fishing, due to the increased enemy spawn rate that will constantly damage and knock them.
The player may also choose to box themselves in with blocks to avoid melee-based enemies, though this has no effect on enemies with wall-piercing attacks, such as the Dark Caster and Cursed Skull.
