New 8th Tyranids Codex Rules Changes Breakdown

Tyranid Carnifex Wal Hor

The new Tyranid Codex is finally here, and we have the points cost, new rules, and datasheet changes that you will see inside. Come check them out!

We’ve collected up the latest on the new codex book and compiled it into one HUGE post, with our own review video at the end as well.

The Codex: Tyranids is 128 pages full of great lore and even better Stratagems, Warlord Traits, psychic powers, and bio-artifacts. The 7 Hive Fleets represented in this codex are all strong in their own right and have multiple options and combos that will suit anyone’s play style.

So far fans seem to be enjoying the new rules, and are looking forward getting some serious games under their belt starting this week.

From what we’ve seen do not expect this codex to be full of point costs reductions. It isn’t. This codex is more about how the Tyranids will play and about getting more power for points. Early hive fleet favorites are Behemoth for their super assaulty nature, and Kronos for their ability to mess with psykers on a much larger scale than just the baseTyranid rules.

Let’s dive and and see what is new!

Tyranids Codex

8th Edition Hive Fleet Special Rules:

Behemoth

  • Hive Fleet Attribute: Re-roll failed charges.
  • Warlord Trait: A To-Wound roll of 6+ during the Fight Phase deals 1 additional damage.
  • Stratagem: Brute Force (1CP)
    Use when a Benemoth unit successfully completes a charge. Roll a dice for each model in the unit that ended it’s charge move within 1” of an enemy model. For each roll of 6+, the enemy unit suffers 1 Mortal Wound. If the charging unit was a Monster, it instead inflicts a Mortal Wound on a roll of 2+.


Gorgon

  • Hive Fleet Attribute: Re-roll 1’s To-Hit during the Fight Phase.
  • Warlord Trait: At the end of the Fight Phase roll a dice for each unit within 1”/3”* of the Warlord. On a 4+ that unit suffers a Mortal Wound.
  • Stratagem: Hypertoxicity (1CP)
    Use during the Fight Phase. Choose a Gorgon unit equipped with Toxin Sacs. The biomorph does 1 additional damage on To-Wound rolls of 5+ instead of 6+.


Hydra

  • Hive Fleet Attribute: Re-roll all failed To-Hit rolls during the Fight Phase for units who outnumber their opponents.
  • Warlord Trait: At the beginning of your turn roll a dice for each Wound your Warlord has suffered previously in battle, on a 6+ it regains that Wound.
  • Stratagem: Endless Swarm (2cp)
    Select a destroyed unit of Termagants, Hormsgaunts, Gargoyles, or any Hydra Infantry unit that has been completely destroyed. Add an identical unit to your army and set it up as reinforcements wholly within 6” of any board edge, and more than 9 inch from any enemy units.

Not sure if this is actually the Hydra stratagem, if it simply has a bonus when used by Hydra armies. The wording implies the later, but I couldn’t find another trait that specifically mentions Hydra in the leaks.

Jormungandr

  • Hive Fleet Attribute: A unit with this adaptation (other than units that can Fly) always has the benefit of cover for the purpose of shooting attacks. If the unit advances or charges, however, it loses the benefits of this adaptation until the start of your next movement phase.
  • Warlord Trait: Enemy units do not benefit from Cover against attacks made by the Warlord or friendly units within 3” of the Warlord.
  • Stratagem: The Enemy Below (1CP)  Use this Stratagem during deployment when setting up a Jormungandr Infantry unit. Instead of deploying normal set this unit up underground. When you set up a unit of tunnellers (Raveners, Trygon, Trygon Prime, or Mawloc) any number of units that have been set up underground may deploy with them. Place that unit within 3” of the tunneller and more than 9” away from any enemy units.

Kraken

  • Hive Fleet Attribute: Units may charge after Falling Back.
  • Warlord Trait: Choose a unit within 6” of the Warlord, it may fight first in the Fight Phase even if it didn’t charge.
  • Stratagem: Opportunistic Advance (1CP)  Use in the Movement Phase. Choose a Kraken unit that does not have the Fly keyword. When Advancing you can double number you roll when determining how much to add to the unit’s Movemnt characteristic.

Kronos

  • Hive Fleet Attribute: If a unit does not Move, it may re-roll 1’s To-Hit when shooting.
  • Warlord Trait: If an enemy Psyker within 18” of your Warlord fails a Psychic Test they suffer D3 Mortal Wounds.
  • Stratagem: Against Shadows (1CP)  Use when an enemy psyker attempts to cast a spell within 24” of a Kronos unit. That psyker can only use one dice for their psychic test.

Leviathan

  • Warlord Trait: After deployment, but before the first game turn, you may re-deploy your Warlord.
  • Stratagem: War On All Fronts (1CP)
    Use during the Fight Phase. Select enemy unit within 1” of one Flying and one non-Flying Leviathan unit. You may re-roll all To-Hit and To-Wound rolls of 1 for attacks against the enemy unit made by friendly Leviathin units.

At any point in the game, they can appear within 6″ of a node. If an enemy model gets within 9″ of a node, that node is removed. The Genestealers are considered lost if all nodes are removed before they can deploy.
