You usually don’t need to destroy the Brine Pool at all — the Brine- infused Rod is mainly used to fish there until a Brine Storm/Brine Surge-style event starts, and player reports say the trigger is more about repeated fishing and server-wide disturbance than a fixed “damage” amount. Sources I found describe it as starting more often with the rod, especially with more players in the server, but they do not give a precise required disturbance number.

What people are saying

  • The Brine-infused Rod can increase the chance of a Brine Storm spawning while fishing in the Brine Pool.
  • Some players say more people fishing means more disturbance and a faster trigger.
  • One community post mentions a maximum disturbance cap of 5000, but that appears to be forum speculation rather than an official rule.

Practical takeaway

  • Go to the Brine Pool.
  • Fish there with the Brine-infused Rod.
  • Use a rainy setup if the event requires it in your version of the game.
  • Expect it to be chance-based , not tied to a clearly documented “X amount of disturbance” threshold.

Bottom line

There’s no verified exact amount of disturbance needed from the sources I found; the safest answer is that you keep fishing with the Brine-infused Rod until the event spawns, and it seems easier with more players or storm- friendly conditions.

TL;DR: no confirmed exact number, just keep fishing in the Brine Pool with the Brine-infused Rod until the Brine Storm/Surge triggers.
