Respond to the warning by getting under cover
When a moving chaos storm warning appears, head for shelter inside a crystal pillar’s coverage. The storm travels across the world, so give yourself time to reach the protected part of your base. This is one reason to keep a route home in mind when you leave to gather or explore.
Treat it as a roaming event
A chaos storm moves across the map. That makes it different from a local corrupted area you enter to reach a dark crystal. The developer’s storm spotlight describes chaos storms as traveling world events and explains why a crystal pillar belongs at the center of a base.
Wait for the storm to move on
Stay within the protected part of the base while the event passes. If there are raid enemies, deal with immediate threats and leave room to fall back under the shield. The October 22 demo notes say raid enemies lose their corruption as the storm leaves. Check your surroundings before heading out again.
FAQ
Can a chaos storm reach my base outside a local storm area?
Yes. It roams across the map rather than staying in one corrupted area.
Should I look for a local crystal to end a moving chaos storm?
Use the warning to get to pillar shelter and let the event pass. Breaking a dark crystal is how you clear a local cursed storm.
What if I am already at home when the warning appears?
Move into the part of the base covered by the pillar. Give yourself a route back under the shield if you need to move during the event.
