Hailstorms, added by the Weather Mobs idea pack, occur when a Rainstorm is happening between about 10:00 p.m. Minecraft time and 3:00 a.m. Before or after those hours, it will turn back to rain. They are also triggered by summoning the Hail Boss. While it is hailing, the player takes 9px-Half Heart.svg every 10 seconds, making it dangerous to be out in. Every time they take damage, there is a 1% chance that the Hail Boss will spawn. Mobs called Angry Hail may also spawn in Hailstorms. A new block called Hail will also appear on the ground. 


  • If the elevation is high enough, Hailstorms will not occur at all because it is snowing instead.
