This is an expansion of the Codex - Tyranids: /tg/'s 9th Edition

Nidhoggr Hive Fleet

Rules

All the rules in this section are meant to be used alongside the Tyranids 9th Edition Codex.

Hive Fleet Adaptation

Burning Fury: The fiery beasts of the Nidhoggr are fueled by a perpetual burning rage capable of trampling all but the most durable of foes.

Each time a unit with this adaptation fights, if it made a charge move, was charged, or performed a Heroic Intervention this turn, then until that fight is resolved, add 1 to the Attack characteristic of models in that unit, 2 if that unit is a Monster.

Adaptive: Each time a unit with this adaptation makes an attack, an unmodified wound roll of 6, improve the Damage characteristic of that attack by 1.

Hyper-adaptation: You can swap this hive fleet’s Adaptive rule for one of the followings:

-Augmented Ferocity: Add 1 to charge rolls made for units with this adaptation.

-Extra-caustic Fumes: At the end of the turn, roll a die for each enemy unit within 3" of a Monster model with this adaptation; on a 4+, that unit suffers D3 mortal wounds, 3 on a roll of 6.

-Scorching Salvoes: Each time a unit with this adaptation makes a ranged attack, the target does not receive the benefits of cover against that attack.

-Tectonic Shell: Each time an attack is allocated to a Monster model with this adaptation, subtract 1 from the Damage characteristic of that attack (to a minimum of 1).

-Unfeeling Resilience: Models with this adaptation whose characteristics can change as they suffer damage are considered to have double the number of wounds remaining for the purposes of determining what those characteristics are.

-Unstoppable Swarm: Units with this adaptation can ignore any or all modifiers to their Move characteristic, Advance rolls and charge rolls.

Stratagem

Internal Sun (2CP): The creature of the Nidhoggr can produce an incredible heat seemingly out of nothing. It is not known how those beasts manage to survive but one thing is certain, no simple soldier can withstand these iron-melting temperatures.

Use this Stratagem at the end of your Fight phase. Choose a single Internal Furnace Nidhoggr model and roll a die for each non-Nidhoggr model within 1" of it; on a 3+ that model's unit suffers a mortal wound.

Burning Rain (1/2CP): As the flaming terrors of the Nidhoggr soar the skies, the darkness is driven back by millions of tiny drops of burning acid that fall down like deadly shooting stars.

Use this Stratagem at the end of your Movement phase and select one NIDHOGGR Aircraft unit from your army. Select one enemy unit that was passed over by the selected model. Roll six D6s for each Vehicle or Monster model in that unit and roll one D6 for each other model in that unit (to a maximum of ten D6s): for each 3+, that unit suffers 1 mortal wound; if your selected unit is Titanic, then double the amount of D6 rolled for each model to a maximum of twenty D6s. An Harpy may not be chosen as the target of this Stratagem and use its Spore Mine Cysts rule to inflict mortal wounds in the same turn. This Stratagem costs 2 Command Points if the targeted model is Titanic, otherwise it costs 1 Command Point.

Warlord Trait

Hellspawn: The leader beast of the Nidhoggr is a demonic creature of ash and hatred. The heat produced by its body reaches impossible heights and all enemies kneel down and melt at its sight.

During deployment, you may instead set this model up deep underground, waiting for the right time to strike. At the end of any of your movement phases this model can burrow up and out of the rock in a fiery eruption of magma and razor-sharp limbs, set this model up anywhere on the battlefield that is more than 6" away from any enemy models, after that, every enemy unit within 9" suffers D3 mortal wounds on a roll of 2+. In addition, at the end of every turn roll a die for every non-NIDHOGGR unit within 9” of this model; on a 4+ that unit suffers D3 mortal wounds.

Each time you roll a wound roll of 6+ for this weapon, the target suffers a mortal wound in addition to any other damage. Enemy models in base contact with a model equipped with this weapon have to subtract 1 from their hit rolls.

Roll a die if a model that has suffered a wound by this weapon but that hasn't been removed as a casualty; if the result is higher than that model's remaining number of wounds remove it from play.

Upgrade Biomorphs

To represent the strange adaptations of the Nidhoggr Hive Fleet, Nidhoggr Monster unit in your army may take any of the following biomorphs as upgrades.

• Geothermal Jets: In your Movement phase, if this model Remains Stationary or moves a total distance of less than half its Move characteristic, until the end of the turn, each time this model declares a charge, roll one additional D6 and discard one of the dice when making the charge roll. - 10 pts.
• Internal Furnace: Roll a die each time this model destroys an enemy Vehicle during the Fight phase; on a 4+ that model regains D3 lost wounds. - 10 pts.

Available Biomorphs

The highly erratic nature of the Nidhoggr hive fleet differentiates it from other tendrils. Due to the intrinsic nature of the biomorphs present, the smaller types such as gaunts and genestealers wouldn't be able to survive the extreme internal heat. For this, the Norn Queen known as the Molten Empress privileges bigger organisms and has adapted new strains to fill the gaps of the discarded specimens.

While creating a Nidhoggr army, you may not include any of the following units: Broodlord, Old One Eye, The Swarmlord, Gargoyles, Hormagaunts, Termagants, Genestealers, Pyrovore, Parasite of Mortrex, Ripper Swamrs and/or Sky-slasher Swarm.

You may instead include the following units: X, Linnorm, Surtr-Class Swarmlord, Suam'O, Ignis-Class Pyrovores, Wyrm Swarm and/or Magma Corer.

• Burrow: At the beginning of any of your Movement phases, the Linnorm can burrow. Remove it from the battlefield - it can return as described in the Underground Eruption ability. The Linnorm may not burrow and return to the battlefield in the same turn. If the battle ends while the Linnorm is underground, it is considered to be slain.
• Death Throes
• Extreme Omnivore: The Linnorm gains a Fuel Token for each wound inflicted on a Vehicle, up to three for any single model.
• Lurker: The Linnorm automatically enters from Reserve on the first turn.
• Magma Furnace: At the start of the Shooting phase you can spend 4 Fuel Token to let the Linnorm perform a single shooting attack as if it had a Dragon Cannon.
• Shadow in the Warp
• Synapse
• Terraform: During the Shooting phase a unit with this rule may opt to devour an inorganic terrain piece (buildings, rocks, wreckage etc) it touches. If it chooses to do so, you may move it to any point wholly within that piece of terrain before removing it from the field. This counts as advancing for all intents and purposes. This action earns a Fuel Token. Up to three Tokens can be spent for a +2" total movement increase or any number to increase the Attacks by +1 in the Fight phase.
• Underground Eruption: During deployment, you can set up the Linnorm underground instead of placing it on the battlefield. At the end of any of your Movement phases, set up the Linnorm anywhere on the battlefield that is more than 1" away from any enemy models, then roll a D6 for each enemy unit within 2" of it; on a 1 the unit escapes unharmed, on a 2-3 it suffers D3 mortal wound, on a 4-5 it suffers D3+3 mortal wounds, and on a 6 it suffers 6 mortal wounds.

Lords of War

Magma Corer

Magma Corers are enormous Tyranid biomorphs engineered for planet consumption. These hulking monsters possess a shell a thousand times stronger than diamonds that makes them nigh-invulnerable to small arms fire and whose purpose is to enable the creature to dig into the planet's mantle and start a chain reaction that results in the detonation of multiple fault lines around the crust, breaking it apart and hampering the native forces' resistance. This process is fatal to the Magma Corer but it's a small price the Hive Mind is willing to pay. But their powerful strength isn't to be feared only up-close, debris, tanks, and even buildings are thrown by the creature thanks to its incredible limbs. A Magma Corer is a death sentence incarnated, for everyone and everything standing on solid ground.

This unit contains 1 Magma Corer (Power Rating: 100).

-Gigantic Shoveling Claws

Weapon	Range	Type	S	AP	D	Abilities
Gigantic Shoveling Claws	Melee	Melee	x2	-6	4D3	When attacking with this weapon, you must subtract 1 from the hit roll. If a Vehicle or Monster (that has 18 wounds or less) is slain by this weapon, pick an enemy unit within 24" of the bearer and roll a number of D6s equal to the wound characteristic of the destroyed model. For every roll of 4+, that unit suffers 1 mortal wound.

Special Rules: <tabs> <tab name="Burrowing Nightmare"> At the beginning of any of your Movement phases, any Magma Corer that is not within 1" of an enemy unit can burrow. Remove it from the battlefield – it can return as described in the Magmatic Eruption ability. A Magma Corer may not burrow and return to the battlefield in the same turn. If the battle ends while the Magma Corer is underground, it is considered to be slain. </tab> <tab name="Impervious Chitin"> Attacks made against this model suffer a penalty of 1 to the wound roll and a penalty of 2 to its AP characteristic. In addition, attacks made against this model don't receive a bonus to their damage roll, regardless of any special rule or stratagem (es. "melta" weapons don't get a bonus to their damage if they fire at this model and it's within half of their range). </tab> <tab name="Magmatic Eruption"> During deployment, you can set up a Magma Corer underground instead of placing it on the battlefield. At the end of any of your Movement phases, set up the Magma Corer anywhere on the battlefield that is more than 1" away from any enemy models and more than 6" from any other Magma Corers set up this way this turn, then roll a D6 for each enemy unit within 9" of it; on a 1 the unit escapes unharmed, on a 2-3 it suffers 2D3 mortal wound, on a 4-5 it suffers 2D3+3 mortal wounds and on a 6 it suffers 3D3+3 mortal wounds.
