@JeremyECrawford can I get your ruling on the Iron Flask? Does it work with creatures native to the plane you're in? Do they get to save?

The iron flask targets only a creature native to another plane of existence. #DnD https://t.co/967kYJwqGT

@JeremyECrawford Why? Why would you design it like that?

The iron flask has targeted only creatures from other planes since the item debuted in the original Dungeon Master's Guide in 1979. #DnD https://t.co/ZS2hcXgHIv

@aaronloebWhy did you design it that way in 1979?! Seven-year-old me just had to have it that way!

@JeremyECrawford If I told E. Gary once, I told him 1,000 times: "Don't let that Crawford kid design magic items!"
