Frozen caves and petrified forests

Frozen caves spawns below colder biomes (Snowy tundra, ice spikes, etc). They will have a new variant of stray known as frost strays. And they have a new crystal type known as frost crystal. When broken, they drop frost shards (much like amethyst) and can be used to make frozen glass. When the frozen glass is placed atop a beacon it will add the freezing effect to the beacon and will grant the player immunity to the freezing effect within the beacon’s range. Also, if the same is done with tinted glass, it adds blindness to the effects.

Petrified forests biome spawns in upper surfaces of the world, usually below forest biomes. They have a brand new wood type called petrified wood, as well as petrified grass. The wood is a brownish green and has to be broken with an iron axe to get.
