Ashes of Yggdrasil

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 Codex - Tyranids: /tg/'s 8th Edition.

Hive Fleet Adaptation

White-hot Ammo: The bullets shot by the Nidhoggr aren't simple creatures of flesh but fiery projectiles engulfed in flames, able to burn through any target that stands too close to the Great Devourer servants.

Each time a model with this adaptation shoots an enemy unit that is within half range of its weapon's maximum range, add 1 to the wound 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 Nidhoggr model from your army equipped with the Internal Furnace Biomorph. Roll a die for each non-Nidhoggr model within 1" of it; on a 4+ that model suffers a mortal wound.

Nom Nom Nom... ALWAYS ANGRY!!! (1CP):

Use this Stratagem after an ANGRY MARINE INFANTRY unit is destroyed in close combat by a TYRANID unit, that unit gets the ALWAYS ANGRY! rule for the rest of the battle.

Burning Rain (2CP):

Use this Stratagem at the end of your Movement phase. Select one enemy unit that was passed over by a NIDHOGGR unit with the FLY keyword. Then roll 3D6 for each VEHICLE or MONSTER in the unit, and roll a D6 for every other model in the unit, up to a maximum of 12D6. For each roll of 3+, the target unit suffers a mortal wound.

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.

Enemy models in base contact with a model equipped with this weapon have to subtract 1 from their hit rolls.

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).

Name	M	WS	BS	S	T	W	A	Ld	Sv	Pts/model
Magma Corer	12"	3+	4+	10	9	31-45	6	6	2+	2000

-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.
