What Is a Sky Shard Eruption?

A Shard Eruption is a recurring event in Sky: Children of the Light where a crystal shard falls into one of the game's five realms — Daylight Prairie, Hidden Forest, Valley of Triumph, Golden Wasteland or Vault of Knowledge — and cracks open the ground around it. Players who dive in and grab pieces of the shard before it disappears are rewarded with Wax or Ascended Candles. Sky Shard tracks exactly when, where and what kind of shard is erupting, so you don't have to guess or wait for the in-game warning sign at the realm gate.

There are two kinds of shard eruptions. A black shard is the regular eruption — it happens more often, gives Wax, and is safe to collect solo. A red shard is the strong eruption — rarer, pays out Ascended Candles instead, and drops a "wax monster" that chases you off the shard piece, so most players group up before going for it. Not every day has a shard eruption; each of the five schedule groups skips two fixed weekdays, which Sky Shard accounts for automatically.

Frequently Asked Questions

How many shard eruptions happen per day?
Three, on days when a shard is scheduled. Black shard eruptions land 8 hours apart; red shard eruptions land 6 hours apart. Each eruption lasts roughly 3 hours 51 minutes from landfall to close, with a short ~8 minute 40 second tremor warning beforehand.
What's the difference between a red shard and a black shard?
Black shards are the regular eruption type — more frequent, reward Wax, no danger. Red shards are the strong eruption type — reward Ascended Candles, occur on an odd-day cycle, and spawn a wax monster that will knock you off the shard if it catches you.
How is the Sky Shard eruption schedule calculated?
Sky's day-of-month parity decides red vs. black, and a fixed rotation decides which realm and location each day lands in. This pattern isn't published by the developer thatgamecompany — it was reverse-engineered by the Sky community over time, and Sky Shard computes it live in your browser rather than fetching it from a server.
When do the daily and weekly resets happen?
Daily reset is 00:00 Sky time every day, refreshing quests, candles and the Realm gate. The weekly reset — when Eye of Eden resets — is Sunday 00:00 Sky time. A Traveling Spirit arrives Thursday 00:00 and departs Monday 00:00, also on the Sky clock.
What timezone does Sky Shard use?
All in-game timing runs on Sky time, which is America/Los_Angeles. Sky Shard shows every countdown in your local time by default — tap the timezone button to switch to Sky time instead.
