Ice spikes, and ice spikes biome Ice crystals (glowing and shaped like amathyst shards) Falling ice blocks, ice-illiger mob When falling ice drops it breaks upon impact on ground, but you can make fragile ice block and place it on top of blocks and open it with pistons in the form of a trap and you can stack them on top of each other to multiply the damage. Crafted with ice balls, mined from icey snow, snow that is the colour of ice but cracked texture and slightly powdery ice slurry. Can be stacked like snow, these don’t do damage if they fall but the fragile/falling ice block does do damage. Ice spikes also do damage. Ice caves. Mob variants replace to, Ice spider. Frozen zombie.frost creeper which explodes into powdered snow attempting to trap and freeze you, or it just explodes with the freeze cloud and you can’t move for a few seconds, the frost creeper being blue.
