Calamity Gem is a progression gem for equipment upgrading. It is not a safe stat filler like a routine material, because the official Gems page warns that Calamity Gem has a low chance to destroy the item when used.

Quick Answer

QuestionAnswer
What is it?A gem used in the equipment upgrade loop.
Why is it risky?It can potentially destroy the item when used.
Is it a normal crafting material?No. Treat it as a high-risk upgrade item.
Should beginners use it?Usually no, unless the item is replaceable or the player accepts the risk.

When To Use It

Use Calamity Gem only when the upside is worth the loss risk. Good candidates are duplicate gear pieces, replaceable test items, or gear that would be retired soon anyway.

Avoid using it on:

  • your only strong weapon;
  • gear with rare Echoes you cannot replace;
  • equipment that already consumed expensive Souls or gems;
  • party-critical gear before a dungeon run.
