Lunar Hail
Exclusive to: 
This content is available only after activating the 
Lunar Rift
Lunar Hail is a weather phenomenon exclusive to Don't Starve Together, introduced in From Beyond.
Once Lunar Rifts are activated, hail will periodically start falling in the form of Moon Shards and Infused Moon Shards. When they collide with the ground, they have a 25% chance to not break, but they only remain for 5 seconds, unlike resources that fall from Earthquakes in the Caves. If one of these falling objects hits a player, it deals 30 damage. Wearing armor reduces this damage as normal.
A few things fully prevent damage from Lunar Hail:
- Standing under any Tree
- Equipping an Umbralla in hand
- Wearing Bone Armor (on its normal 5 second cooldown)
And these things prevent the hail from falling in the area at all:
- The Umbralla activated on the ground
- The canopy of a Great Tree Trunk or Above-Average Tree Trunk
Lunar Hail happens every 10 days and lasts up to 90 seconds. Unlike regular Rain, these hail storms do not cause Wetness. If it is raining when a hail storm starts, the rain is overridden.
Trivia
- Lunar Hail was introduced in the Host of Horrors update.
- On initial beta release prior to Update 575729, Lunar Hail would happen every 2 days and last up to 60 seconds.
- Beta update 576473 removed the hail's ability to damage creatures other than the player; the developers still intend to make it do this when they "expand on this feature along with a proper set of mechanics for protecting creatures." [1]
