Lagiacrus are Leviathans introduced in Monster Hunter 3.

Appearance[]

Lagiacrus is a monster with serpentine body, roughly resembling a crocodile with a long neck. Its body is covered in blue shells along its head, back, and the base of the tail, while the underside is light brown in color. Adorning its head is a pair of brown color horns, with three pairs of dermal spikes of the same color on its back. Its tail flare out horizontally at the base, before turning laterally flat with a fin at the end. Its mouth, in additiong to a jaw full of small teeth, it also has a roll of shell spikes on both upper and lower jaw, arranged like a second row of jaw.

When a Lagiacrus is fully sunbathed, it turns a dry grayish-blue color and its dermal spikes turn brown. When it returns to the water, Lagiacrus regains a striking deep blue color and its spikes return to their original color of a very light beige.

Abilities[]

The dermal spikes on its back glow white when it is using strong thunder attacks, and its mouth gurgles with Thunder when it is enraged.

Habitat[]

Lagiacrus is found only at the Deserted Island, Flooded Forest and Misty Peaks. It's most at home underwater, but is more than capable of fighting on land.

    • Both are the only old flagship monsters that can be fought in 3U's low ranked quests.
  • The theme; Tremors on Land and Sea - Lagiacrus of Lagiacrus was voted among the top 10 music themes in the Hunters' Choice: Top 10 Monster Themes - Monster Hunter 20th Anniversary[ref>Hunters' Choice: Top 10 Monster Themes - Monster Hunter 20th Anniversary</ref>

  • Lagiacrus shares some of its physical attacks with Royal Ludroth and Agnaktor.

Monster Hunter 3

  • Lagiacrus is the first Leviathan of its kind to be encountered in Monster Hunter 3.
  • When encountered for the first time offline, in the 1* Village Quest: "Guts- It's What's for Dinner"; Lagiacrus cannot be killed. Its body parts can be broken, and its tail can be carved, but it will only go as far as limping, and cannot be killed until the Urgent Quest in the Village.
  • When present in Deserted Island, Lagiacrus will, on rare occasion, leave the water and venture no further inland than Area 5.
  • Even if the Lagiacrus' tail is cut or its parts broken in the "Trial of the Sea Dragon" urgent quest, it will return in "Fell the Lagiacrus" healed and unwounded.
  • The Lagiacrus is one of only two monsters in Monster Hunter Tri to have a weapon in every category. The other is Alatreon.
  • The only electrical attack Lagiacrus can do on land is spitting thunderballs. Lagiacrus is not able to utilise its shell shockers on land.

  • Monster Hunter 3 Ultimate

  • Breaking its dermal spikes reduces its ability to use electrical attacks.
  • When low on stamina, it will fail to use its electrical charge attacks.
  • Hitting Lagiacrus with any kind of bomb (including Sonic Bombs and Crag/Cluster shots) underwater may cause it to drop an item.
  • A Lagiacrus either will eat an Epioth, or come up on land for air to recover Stamina - however, both often give no indication of Stamina recovery.
  • The Lagiacrus is the biggest Leviathan that dwells in the water, since the Ceadeus is considered an Elder Dragon.
  • When Lagiacrus hits an underwater pillar or a rock and destroys it, it may drop an item (Offline mode only).
  • Lagiacrus' roar requires Earplugs to block.

  • Monster Hunter Generations

  • Lagiacrus uses a drastically different set of electrical attacks to compensate for the removal of underwater combat. However, lore-wise, Lagiacrus should not be able to use its shell shockers on land. Using shell shockers on land is an ability unique to Ivory Lagiacrus.
  • When enraged, thunder will surge around its horns.
  • Lagiacrus will prey on Kelbi to recover stamina.
  • In G Rank Lagiacrus gains a powerful, short-ranged thunder blast from its mouth. It also taunts less frequently.

  • Monster Hunter: World

  • Lagiacrus was prototyped early in the development of Monster Hunter: World, but was cut from the final game due to animation issues.
  • It would have dominated Anjanath in turf wars, like Rathalos, only in the prototype the turf war resulted in Anjanath's death.

  • Monster Hunter Wilds

  • It will be added in the game's second title update.

  • Monster Hunter Stories 2

  • Lagiacrus is a Power type monster. It also attacks with Double Fang.
    • Opposing Lagiacrus’ turn to Speed attacks, Electro Breath, and Bolt Pressure when enraged, and Technical attacks and Wretched Water when its charged with Electrify.
  • When charged, its back crystals will glow and become a breakable part, which must be broken to return to normal.
