Description
Packed Ice is crafted from nine regular ice blocks arranged in a 3×3 grid, yielding one block per recipe — a steep nine-to-one compression that makes harvesting and stockpiling regular ice the rate-limiting step. The block also generates naturally in ice spike biomes (the rare ones with tall vertical ice columns) and at the cores of certain icebergs in frozen ocean biomes.
Three mechanical differences from regular ice make this variant valuable. First, it does not melt under any light source, unlike regular ice which becomes water under torchlight. Second, it is fully opaque — light cannot pass through it, allowing builders to use it structurally without unwanted ambient leakage. Third, boats travel measurably faster across this surface than across regular ice, though noticeably slower than across blue ice. Players who build long-distance ice highways often pave them with this material as a cost-balanced compromise between speed and material investment. Mining requires a silk-touch tool to retrieve the block; without it, the block drops nothing.
