D&D nerds - anyone know if there’s been a ruling on whether using a necklace of missiles breaks invisibility? The action is Use Item, and as it’s neither an attack nor a spell, seems it technically would not.

The question came out of a conversation that started with the realization that the "help" action doesn't break invisibility. This spawned the idea of the invisible tactician, who just spends all his time invisible, using help actions and making trouble. It's a fun idea.

But it then lead to "Ok, what else can you do without breaking invisibility?" and it turns out the list may be fairly long.

And lead to some reading of the wording of several magic items.

Now, most of them explicitly say "spend a charge to allow you to cast X", so that's pretty clear cut.

But a some of them are "spend a charge for [effect]", which is less so.

And there are totally reasonable use cases. Drinking a potion probably shouldn't break invisibility.

Now, all this becomes a non-issue (or only an edge case) if we adopt a common sense interpretation of "attack" but it's a term that has specific meaning.

I should also add, however this goes at our table will be fine. Whichever way it goes, we'll all be on the same page, and NPCs will be able to do whatever we do.

And, honestly, I don't want NPCs to be able to do this!

(And I always forget that the Necklace of Missiles is the Necklace of Fireballs these days. Get off my lawn!)
