The Cragmaw Mire is a Hardmode, post-Aquatic Scourge mini boss that spawns during the Acid Rain event. It will always spawn underwater on the Sulphurous Sea's ocean floor.


The Cragmaw Mire is a gravity-affected and mostly stationary enemy. It cycles randomly between three attacks:

  • Fires an even ring of five Cragmaw Mire Spikespikes around itself twice in quick succession. It switches to another attack after four seconds have passed.
  • Teleports above the player and attempts to drop directly onto them. On impact with a surface, an Sulphuric Nukesplosionexplosion is created alongside a burst of 12 homing Acid Dropletacid droplets. It switches to another attack after performing two slams.
  • Teleports underneath the player and charges up a Cragmaw Mire Beamlaser beam for one second. The laser beam lasts for two seconds and periodically releases homing laser beams in random directions. It switches to another attack after the acid droplets fully dissipates.

Tier 3

  • Teleports faster in the laser beam attack and takes 25% less time to charge the laser.
  • Teleports faster in the slam attack and falls 26.32% faster.
  • Fires three more spikes per ring with increased projectile speed and takes 21.74% less time to fire, allowing it to fire three rings instead of two.
  • Transforms into its second phase at 70% / 85% Revengeance Mode health, changing its appearance.
    • Gains the ability to fire a Cragmaw Vibe Check Chain tether that attempts to grab the player, reeling them into itself if it lands. The tether has a lifetime of six seconds regardless of whether it hits or not.
    • Fires one additional spike per ring and takes 13.89% less time to fire.
    • Teleports even faster in the slam attack and falls 6.25% faster.
    • Teleports even faster in the laser beam attack.


  • In the Get fixed boi seed, if the player gets latched by its tether, a floating piece of text will appear above them saying "Vibe Check!".


  • The Cragmaw Mire spawns under the water, so it is recommended that the player dives into the water to lessen the chance of missing potential spawns.
    • Bringing accessories that aid with underwater combat can be very helpful.


  • The BestiaryBestiary entry for the Cragmaw Mire: "A mostly immobile creature that dwells in the depths of the radioactive wasteland, it boasts an exoskeleton harder than titanium to defend its core. To compensate for its lack of movement, it has formed a symbiotic relationship with a worm that reels in prey in exchange for protection."
  • The Cragmaw Mire's appearance was inspired by a submission for a sulphurous sea design contest that was held on the Calamity art server. The original artwork, made by Ox#8375, used the name "Azufre Piercer".
  • The tether is referred to as 'CragmawVibeCheckChain' in the mod's source files.
  • The jaw of the Cragmaw Mire was inspired by a bear trap.


These history sections are still a work-in-progress, and may not yet contain changes relevant to the current version of the Calamity Mod.
  • Now properly displays vanilla debuff colors and Hunter Potion effects.
    • Added a map icon.
    • Now drops its Relic at a 100% chance instead of 25%.
    • Added it to Boss Checklist.
    • Reworked AI:
      • Now randomly selects a range of three base attacks: dropping below the player and firing a laser beam, dropping onto the player and creating an explosion and homing acid droplets on impact, and firing a ring of spikes.
      • Spikes are no longer affected by gravity and can now travel through tiles.
      • The laser beam now releases homing acid droplets.
      • Decreased tether lifespan from 7 seconds to 6 and it pulls the player more slowly.
      • No longer spawns enemies and no longer has damage reduction.
    • Now vulnerable to electricity debuffs, but resistant to water, sickness, and heat debuffs.
    • Nerfed tier 3 health from 146,600 / 234,560 Expert Mode to 80,630 / 129,008 Expert Mode.
    • Nerfed damage reduction from 60% to 50%, 40% to 30% when the player is submerged.
  • Nerfed tier 2 health from 6000 / 9600 Expert Mode to 4000 / 6400 Expert Mode.
