Impaling Caves

Caves are repetitive and have not exciting 2 years since after there initial release. But if biomes ever added to caves, one would be rare yet frightening. The Impaling Caves would be smothered with new types of blocks, all known as Fragile Stone. This stone would look almost identical to stone but with a slightly darker tint and would have the physics of sand. Another block found here would be Sulfer; it would be explosive, and it would be the first ore to have physics applied to it. If it falls from a drop of more than 20 feet, it will explode for how unstable it would be. You could place it on the floor and have a flammable line to TNT. Also, being near it could cause the nausea effect on players.
Stalactites would hang from the ceiling and fall on players at any moment doing 15 damage to a player without any armor. And something interesting is that the fragile stone could give physics to any block attached to it, so if a state falls its bring down the ceiling. And physics is only applied to fragile stone is if there is no longer and rock around it to support it so even if the roof were made of fragile stone it would only collapse if there is no stone around it to keep it up: Like scaffolding. Lastly, the main reason a player would like to come here would be Corundum Ore. If combined with a nether star and three netherite ingots, you would be able to craft the Dark Beacon. It could affect a more considerable distance and more substantial effects. Thank you.
