MEEETEORS!!!!

In open world, with small chance will spawn meteor, it will fall and you will see how sky changed color for a second, meteor is pretty similar to air ballons but rarer.

How to find it? Craft Seismograph! You must have it in hand, and as closer meteor is as many signals seismograph gives. (crafts from 4 platinum and 1 magnet inside)

What will be meteors for? First of all a lot platinum, not that a lot just like 16 ig, meteors not a big structure, just small one or big like max 16×16×16 blocks, maybe some iron and inside them will be new ore named Magnet Ore, used for crafting Seismograph, and attracts everything that made from iron, even players in iron armor.

What if meteor will fall on player? It cant, its falls only where no players in radius 200 blocks.
