A copper shortsword actually is a dimensional portal activator that transports you to another game entirely, then takes everything from the game and brings it back into Terraria.I made a similar post to this on Terraria Online, but figured I'd make it here too. The idea is humorously terrible ideas for Terraria, or ideas that make an amount of sense but would never work in practice.
I'll get us started...
* The "beginning of the end "actually IS potentially the end of the world. Fail to defeat the celestial towers in a short enough time, or get defeated by Moon Lord? Your world is deleted.
* Three silver bullets kills werewolves, regardless of actual damage dealt. Also applies to players in werewolf form.
* If you play on your birthday, the Clown will come to party... and blow you up.
