10. The Lookout Made of Packed Ice Bricks
Packed ice bricks are the block I didn’t know I needed. Slabs, stairs, walls, chiselled variant — a full set, finally. I built a small lookout platform at the top of my cave, where the tunnel meets the surface, out of packed ice bricks with a snow brick roof. From up there you can see the whole snowy biome, and at dusk the ice goes this pale blue that no screenshot does justice to. Put a spyglass in the chest up there. You’ll use it more than you think.
