Assassin's Creed Valhalla

They've been around for ages now... at least a year.

But normally they're very rare, random for each player, and only happen in certain locations (we assume they move from one location to another over X amount of time). There are people who have 800+ hours in-game who've never seen one.

And at these locations, there are two more (even more rare) events that can happen - Rainbows in England (with a little pile of 100 silver at the end) and burning statues of Odin. I have only seen one of each of those. Ever.

Also, I've heard a rumor that none of these events will happen if it's raining. From my own experience, I think that's true. However, if you do find one (and are farming it), it won't disappear if it starts raining afterward.

And just in case anyone's not sure how to farm the meteors (and rainbows). After you loot them, ride out a min. of 200 meters away, then head back towards it.

In the meteor's case, another meteor will fall, which you can loot again. And you can repeat that process indefinitely as long as you don't fast travel, die, quit, or reload your game.

In the rainbow's case, another pile of silver will appear. But the rainbow will eventually disappear on its own.

The burning statue of Odin just generates a comment from Eivor, but can't be looted.
