I’m watching a run of the og Zelda, and it’s a staple for Ganon and other final bosses to hide the weapon that can kill them in the final dungeon

Thus, the question

As, clearly, that’s a not completely ineffectual solution

.....think my gremlin brain was turned on and I channeled Magnus from TAZ BalanceMagnus Vores A Rock (TAZ Animatic)

Haha tgat, too, is valid

But you better hope your thing isn’t pointy or the solution might be your conclusion x3

Lock it in a vault that only I have the key to, then keep the key with me at all times.

seal it up inside whatever non-bombable walls are made of

seduce it.

Put it in a safe deposit box at my local bank of choice and let the so-called 'heroes' deal with the federal government if they try and purloin it.

Metafive: Or deal with the Swiss Banks.

coffeeforink: Hell, or banking regulations and bureaucracy in generals.

"I'm here to attain the ancient artifact that can kill the evil emperor!!"

" (clerk sighs heavily.) You'll have to fill out these forms..."

Making a threat of violence in a bank? Silent alarm time.

Get agents I trust into whatever the local religion is and start destroying legends / prophecies of the macguffin, then replace them with similar-sounding legends of a completely unrelated red-herring item. Let the church safeguard that red herring, while the real one is kept in a personal vault.

That last one has all the hallmarks of getting in the ear of the scraggly hermit who publicly scoffs at the fake mcguffin and that the followers are “BLIND FOOLS”

Keep the train going, then. Pay homeless people to shout that the macguffin is fake, but then tell of a third, also useless burgundy herring

With the real one, I might want to figure out the mechanism by which the invincibility is defeated, then use that to lock away the true macguffin, so that the only thing that can break the seal is what's inside said seal

Take a boat out and chuck it into the ocean. Good luck finding it out there, and if they do? More of the ocean is now explored and studied

Make a big show and dance about hiding my One Weakness at the bottom a very deadly and complex labyrinth filled with traps and monsters. Except that’s not really my One Weakness

I actually quietly deposit my One Weakness in a safe deposit box at the bank

ohh that's pretty good
