@JeremyECrawford If someone has a longsword +1, and Dispel Magic is cast on the sword, does the sword become mundane? #DnD

Does dispel magic have any effect on a magic item? Search for "dispel magic" in the Sage Advice Compendium: https://t.co/WWVq6Y8bNj #DnD https://t.co/0leS6tr8YE

Dispel Magic makes magical items and effects inert, magic weapons and items for d4 turns, and artifacts for d2 turns I believe
That was in some previous editions, but not so relative to 5E’s metaphysics. (Some DMs from previous eds — or from Pathfinder — homebrew that as still being true, but it isn’t for 5E.)
