Calamity Befalls: pure damage, nothing else

Updated 25 Oct 2026

The weekly damage check: 16 rounds over 48 hours, an all-damage fleet, why you should fight alone, and the 5-kill daily goal.

The short version

48 hours, individual, server-wide. 16 rounds: 8 a day, every 3 hours from reset, 20 minutes each.
Go all-in on damage. Enemy counterattacks are weak and don't scale, so defence is useless here.
Fight alone. Being in a crowd costs about 7% of your damage.
Kill at least 5 ships in one round to get the daily rewards.
The leaderboard is for show: no extra rewards for ranking.
Rewards: Cocoon fragments and Component Modules.

Each round is 10 waves of a single Calamity Ship, with 10 seconds between waves.
Each ship has more HP than the last. Wave 10 has almost 10 billion HP and isn't meant to die: just keep hitting it until the round ends.

Full damage. Ignore defensive stats and abilities.
Swap out utility and defensive champions (Klara, Doug, Ajita…) for pure damage dealers, even Epic ones. An Epic damage dealer outscores a well-built Legendary tank here.
See Combat basics for how ATK and INT turn into damage.

Calamity portals appear in every level 4, 6, 7 and 9 system (9 locations). Look for the red/pink portal icon on the galaxy map.
Find a spot to yourself, usually in lower-level systems.
Stay in one place. Damage is tracked per location; fighting in several systems at once doesn't add up.
