Iwajira is an enormous corrosive kraggon that can be found in Pyroclast Grotto, a hidden cavern found south of the Fast Travel station in Serenity's Waste.



Iwajira will emerge from the large lava pool within Pyroclast Grotto as soon as every Vault Hunter in the party enters the area. He constantly moves towards his chosen target and alternates between two primary attacks:

  • First, he will lob three corrosive boulders toward his target, which explode a few seconds after hitting the ground, leaving a lingering cloud of corrosive gas. Each boulder has a chance of spawning a Kraggon Pebble or a Kraggon.
  • Second, he will attack with a long-range beam dealing corrosive damage. He is highly accurate with this attack, but it is possible to dodge the beam by quickly moving out of the way.

These two attacks are continually rotated until his defeat.

If his target gets within his large melee range, Iwajira will swing around and swipe with his tail, or perform a quick bite attack, identical to other kraggons. The bite is highly damaging, whilst the tail swipes inflict a powerful knockback that sends Vault Hunters flying.



Location of Iwajira

  • Iwajira's loot drops include:
    • an average drop of 27 moonstones.
    • a chance of purple rarity skins for each class: "Bitter Pill" (Wilhelm), "Last Thing You See" (Nisha).
    • Due to a hotfix at 1/21/15 Iwajira has a chance to drop the Hail.
  • Iwajira's loot can spray all around the cavern besides the concentrated pile where he dies, including in the lava and its surrounding outcroppings.
  • Iwajira was temporarily replaced by the cryo/incendiary kraggon Odjurymir during the in-game Mercenary Day event from December 23rd 2014 to January 5th 2015.
  • Iwajira has an increased chance to drop the legendary Thingy launcher.


  • Iwajira is based on Godzilla.
    • The name Iwajira is a combination of the word Iwa, which means rock in Japanese, and end of the name Gojira, which is Godzilla's actual name.
    • His fins (the spikes running down his back are called fins) resembles those of the millennium series Godzilla.
    • One of his attacks is a corrosive beam out of his mouth, an imitation of Godzilla's atomic breath.
