Powder snow bucket is obtained by using a bucket on a powder snow block or by placing a cauldron in snowy weather and collecting the powder snow when full.
Powder snow buckets are primarily used to place and transport powder snow, which can trap mobs, slow movement, and freeze entities over time. They are essential for creating traps, parkour challenges, and farming stray skeletons, as skeletons that stand in powder snow for too long turn into strays.
