Ruiner Nergigante is a Variant of Nergigante first introduced in Monster Hunter World: Iceborne.


At first glance, Ruiner Nergigante is built similarly to Nergigante, albeit with darker scales and carapace. The variant's defining feature are the metallic spikes that grow in between their regular bone spikes. These spikes are much tougher and make deadlier weapons compared to the typical ones, but they can't be regrown rapidly and takes a longer time to reach full size.

Behavior and Abilities

Unlike most monsters, Ruiner Nergigante will not go all out at the earliest opportunity presented and instead will start off being surprisingly slow and predictable in combat, progressively becoming more brutal and deadly as the fight goes on and as it sustains more damage, with the final phase of the fight being a far cry from how it began.

Ruiner Nergigante grows metallic spikes on its forelimbs, nape, and wings. The growth progresses as the dragon loses health in combat. When they reach full size, the spikes will give a bigger "spike burst" effect to attacks that uses the corresponding body parts, which gives significant damage increase, wider burst radius and Bleeding effect. When used in conjunction with Ruiner Nergigante's late phase move set, fighting the dragon could prove very troublesome.

Curiously unlike its counterpart Nergigante, Ruiner Nergigante displays signs of intelligence and patience, when it fights the hunter on Origin Isle it pretends to be defeated. From there it plays dead till the hunter defeats Shara Ishvalda, weakening the Elder Dragon enough to finally kill and, more than likely, devour some of its bio-energy. A typical Nergigante displays a feral and all-consuming desire to eat Elder Dragons at all costs while Ruiner is willing to let others do the work for it.

  • Ruiner Nergigante replaces the standard Nergigante in Master Rank.
  • Outside of Assignments, any quests that involve Ruiner Nergigante are MR-restricted at MR 100 minimum.
  • Ruiner's Nergigante metallic spikes reach their full size on a single random body part every time its health drops below certain threshholds, which also make it go into the next phase.
    • The shift in phase is signified by an "ultimate attack" where the dragon roars, lifts itself up and does a plummeting attack using the body part that gets its metal spikes fully grown.
      • The location of the spike can be predicted by the roaring itself. After the roar, Ruiner Nergigante will hold one arm higher, signifying that that sides iron spikes are fully grown. This does not signal whether the arm or the wing will grow the metallic spikes. If it's the heads iron spikes, Ruiner Nergigante will let out a very loud and long roar that is different from the limbs counterparts, this version will try to home in at a hunter.
    • Breaking Ruiner Nergigante's metallic spikes reduces the augmentative effect of its attacks. Conversely, its metallic spikes cannot be broken before fully grown.
    • Ruiner Nergigante's metallic spikes do not regrow once broken and counts as conventional part-breaking, meaning players are rewarded accordingly for accomplishing the feat.
    • Ruiner Nergigante's bone spikes only works defensively, meaning it hardens the corresponding body part against physical damage, but does not enable spike bursts or build up its ultimate attack as both functions are overridden by the metallic spikes' mechanic. Breaking the bone spikes on the arms will cause Ruiner Nergigante to fall over.
  • Ruiner Nergigante, along with the regular species, are the only monsters that can be randomly generated in the game which moveset changes as it go through different phases through sustained damage. Other such monsters, like Shara Ishvalda, Behemoth and Kulve Taroth, are locked into specific quests with predetermined conditions.
  • Tempered Ruiner Nergigante did not exist in-game until the second free title update of Iceborne.
    • Ruiner Nergigante has a very slim chance of spawning as Tempered in level 7 of the Forest, Wildspire, Coral, Rotten and Volcanic region in the Guiding Lands. It is guaranteed to spawn as Tempered within a level 7 Tundra region.
