It opened one door. No stats. No rarity color. No tooltip.
Players kept it for the entire playthrough — because they didn't know which door it opened.
That key taught me more about item design than anything I'd read in a GDD.

The principle: deferred meaning
An item doesn't need to be useful right now to feel valuable. It just needs to feel like it will be.
The key created a question the moment players picked it up: what does this open? That question - unrealized, unknown - made it more valuable than any weapon in the game.
Once you see this mechanism, you see it everywhere:

The strange coin an NPC gives you in act one
The locked chest you find before the lockpick
The empty crafting slot with a silhouette you can't fill yet

None of these have immediate utility. All of them have weight.

Two layers every item has — and one that gets ignored
Every item has a functional layer (stats, effects, use cases) and a meaning layer (name, description, context, how it feels to hold).
Most item design focuses entirely on the functional layer. The meaning layer gets filled in at the end, if at all.
That order is backwards.
A sword called "Iron Sword" with 50 attack is a tool. A sword called "The Last Argument" with the same stats and a description reading "Forged the night before a battle no one came back from" is a story.
Same function. Completely different emotional relationship.
