Editing Codex - Tyranids: /tg/'s 9th Edition (section)

====Universal====
*'''Arachnacyte Gland:''' ''The Arachnacyte Gland clutches the spine of its host bioform, its multi-limbed tendrils becoming wedded to the creature’s own flesh. Through these, the bio-artifact floods its host’s nervous systems and organs and lashes it with psychic stimuli, driving the beast on ever faster.''
::Model with Adrenal Glands only. When a charge roll is made for a model with this Relic, roll one additional D6 and discard one of the dice.

*'''Maw Claws of Thyrax:''' ''During the destruction of Thyrax, the dread beast that spearheaded the assault bore a pair of symbiotic fang-lined pincers. These terrible claws consumed both the bodies and the memories of their victims, passing on the assimilated knowledge to the host creature.''
:: Model with Rending Claws, Monstrous Rending Claws or Patriarch Claws only. Add the following to that weapon’s special rule: 'When this model slays an enemy model in the Fight phase, you can re-roll failed hit rolls in all subsequent Fight phases for this model.' In addition, consider the results of the wound rolls made by a model with the Maw Claws of Thyrax as 1 higher to see if the weapon's special rule activates.

*'''Norn Crown:''' ''First named by Inquisitor Kryptman, the Norn Crown is a unique parasitic organism that burrows needle-like cerebral bores directly into the brain of its host, forming a neuro-synaptic link that acts as a hyper-conduit for the Hive Mind. Through this abhorrent union, the Hive Mind’s indomitable will can pour forth to augment and control the hordes of lesser Tyranids that scuttle in the leader-beast’s wake.''
:: Friendly {{W40kKeyword|<HIVE FLEET>}} units do not suffer the penalties to their hit rolls and charge rolls incurred from the Instinctive Behaviour ability whilst they are within 30" of this model. In addition, this model gains the {{W40kKeyword|Psyker}} keyword and can attempt to manifest one additional psychic power in its Psychic phase.

*'''Pathogenesis:''' ''An organism like no other, Pathogenesis is perhaps a throwback to the Tyranids’ genetic origins or a shadow of things to come. Though its motes of psychic awareness are diffused throughout its carrier like a virus, it acts with a singular will. Subverting the body and symbiotes of its host, Pathogenesis causes rapid mutation: cartilaginous tubes and containment spines are lengthened; intercostal muscles are engorged; bio-ammunition are sheathed in a toxic dermis. With its host’s reach and lethality extended, fragments of Pathogenesis can reach out to the bodies of many more prey, by infesting the bio-ammunition or riding through the bio-electric charge. Whether it aims only to spread itself or is actively seeking something in the bodies of its fallen foes, perhaps only time will tell.''
::Add 8" to the Range characteristic of ranged weapons a model with this Relic is equipped with. In addition, when a model with this Relic fires Overwatch or is chosen to shoot with, you can re-roll a single hit roll and you can re-roll a single wound roll.

*'''Resonance Barb:''' ''Within the crowning carapace of this creature are pulsing bundles of nerves, their tendrils are driven irreversibly into the beast’s cortex. The Resonance Barb throbs at sympathetic frequencies with the Hive Mind, transmitting a portion of its cosmic might into the creature’s flesh-form.''
:: {{W40kKeyword|Psyker}} model only. A model with this Relic can attempt to manifest one additional psychic power in your Psychic phase and attempt to deny one additional psychic power in your opponent’s Psychic phase. In addition, when a Psychic test is taken for a model with this Relic, add 1 to the total.

*'''Slimer Maggot Infestation:''' ''Rather than individual organisms, this deathspitter fires a wad of self-replicating slimer maggots. Upon striking their target, these ravenous creatures burrow deep into its flesh before beginning the process of fragmentation and regeneration. Within moments, the host body is devoured from the inside by a wriggling mass of grubs.''
::This Relic replaces the model's two '''Deathspitters with Slimer Maggots'''. In addition, this model and every {{W40Kkeyword|<Hive Fleet>}} unit within 6" may re-roll every wound roll during the Shooting Phase if the fire with any weapon from the ''Deathspitter Weapons'' list.

*'''The Hungering Carapace:''' ''This entire carapace is, in reality, a symbiont creature that leeches onto the host's back and feeds on the pieces of biomass that comes too close to its hidden tendrils.''
:: This model's Armor save is improved by one. In addition, each time you roll a wound roll of 6+ for a melee attack made by its bearer, the target suffers a mortal wound in addition to any other damage; for every model slain by these mortal wounds, the bearer regains a wound lost previously in the battle.

*'''The Miasma Cannon:''' ''The Tyranids utilize all manner of bio-weapons, but none evoke more dread than the Miasma Cannon. Unlike other venom cannons, this weapon fires gobbets of toxin-laden slime so virulent that it reduces organic targets into shapeless puddles of goo in seconds.''
::This Relic replaces the model's '''Heavy Venom Cannon''' and has the following profile:
::{| class=wikitable
|- valign=top
! Weapon !! Range !! Type !! S !! AP !! D !! Abilities 
|-
|'''The Miasma Cannon (Miasmic Spray)''' || 8" || Assault D6 || 7 || -2 || 2 || Blast. This weapon always wounds on a 2+, unless the target is a {{W40kKeyword|VEHICLE}} or {{W40kKeyword|Building}}. This weapon automatically hits its target.
|-
|'''The Miasma Cannon (Miasmic Spit)''' || 36" || Assault D3 || 10 || -3 || 3 || Blast. This weapon always wounds on a 2+, unless the target is a {{W40kKeyword|VEHICLE}} or {{W40kKeyword|Building}}.
|}

*'''The Psyleech Venom Cannon:''' ''This peculiar weapon can fire a special parasite able to disrupt psychic energies, or simply a wave of venomous bodily fluids unto the enemy.''
::This Relic replaces the model's '''Heavy Venom Cannon''' and has the following profile:
::{| class=wikitable
|- valign=top
! Weapon !! Range !! Type !! S !! AP !! D !! Abilities 
|-
|'''The Psyleech Venom Cannon (Salvo)''' || 36" || Assault D6 || 5 || -2 || 1 || Blast.
|-
|'''The Psyleech Venom Cannon (Single Shot)''' || 36" || Assault 1 || 9 || -3 || 2 || You can add 1 to the wound rolls if the target unit has the {{W40kKeyword|Psyker}}, {{W40kKeyword|Daemon}} or {{W40kKeyword|Chaos}} keyword. In addition, the enemy must subtract 2 from Invulnerable saves made against hits caused by this weapon.

*'''The Reaper of Obliterax:''' ''The Reaper of Obliterax, first encountered amongst the re-emergent swarms of Hive Fleet Jormungandr, is a sentient blade resembling a bonesword that discharges highly concentrated bursts of destructive energy. Even the lightest blow from this bio-weapon can result in its target being rent asunder.''
:: Model with Lash Whip and Bonesword or Lash Whip and Monstrous Bonesword only. Add the following to that weapon’s Abilities: 'On a wound roll of 6+, this weapon inflicts double damage.' In addition, a model equipped with the Reaper of Obliterax has a 4+ invulnerable save.

*'''The Venomthorn Parasite:''' ''These engorged bio-ammunition tubes are only the outer form of an ancient symbiotic intelligence that spreads its nerve endings like a fungus throughout both creature and weapon, neurally linking the three together. When it senses prey, the Venomthorn Parasite dominates its two hosts, pushing the weapon symbiote to its limit with pulses of hormonal stimuli until the target is eviscerated.'
::Model equipped with a stranglethorn cannon and/or heavy venom cannon only. When this model shoots with a stranglethorn cannon or heavy venom cannon, do not roll any dice when determining the Type characteristic of that weapon; instead, it has the maximum value (e.g. a Heavy D6 weapon makes 6 attacks). In addition, add 1 to the wound rolls when firing with that weapon.

*'''The Ymgarl Factor:''' ''The Ymgarl Genestealers have long been a cancerous blight on the worlds of the Imperium. Their insatiable voracity is a legend amongst those that have had the misfortune to encounter them and live. Now, dark rumors have surfaced of Tyranid leader-beasts that appear to share the unfathomable adaptability of the Ymgarl Genestealers.''
:: At the start of its movement phase, a model with the Ymgarl Factor must alter its form into one of the three listed below. The bonus gained lasts until the start of its next movement phase. The same form cannot be chosen until all three have been selected at least once. 
::*'''Slashing Claws:''' The model has +D3 Strength.
::*'''Tentacled Limbs:''' The model has +D3 Attack.
::*'''Muscled Carapace:''' The model has +D3 Toughness.

*'''Xenogenic Acid:''' ''This oily black substance continually seeps from the swollen cysts of its carrier. Splashes of the liquid have been seen to flow against gravity towards horrified eyes or compromised armour plates, giving rise to speculation that the acid itself is sentient. Within moments, the horrifying effluence finds its way inside its victims, breaking down the prey’s genetic structure and molecular cohesion until all that is left is a bubbling pile of black bio-matter.''
::Model with Toxin Sacs only. When resolving a melee attack made by a model with this Relic, an unmodified wound roll of 5+ inflicts 1 mortal wound on the target in addition to any other damage.
