Editing Codex - Tyranids: /tg/ edition (section)

==Hive Fleet Strains==
A player may choose one of the following Hive Fleet Strains to gain its effects for their army. Unless otherwise listed, all Hive Fleet Strains ally as Battle Brothers.

*'''Behemoth:''' ''Forward Surveyors:'' Choose one type of enemy unit (eg: Ork Boys, Dark Angels tactical squad, etc); all friendly Behemoth units within the Warlord's synapse range (including himself) gain Preferred Enemy against all units with the chosen name. In addition, Behemoth units may organize into a "Spearhead Swarm" detachment described below.
**'''Spearhead Swarm detachment:''' This is a primary detachment consisting of the following:
*** 2 HQ (1 mandatory)
*** 4 Elites
*** 4 Fast Attack (2 mandatory)
*** 2 Heavy Support
*** 4 Troops
*** 1 Lord of War
*** 1 Fortification
:Сommand Benefits: ''Forward Swarm:'' Units of this detachment may re-roll Reserve rolls (including successful ones), Deep Strike scatter and Outflank results. Additionally, Fast Attack units have Objective Secured, and count friendly Behemoth synaptic creatures as having +6" to synaptic range.

*'''Kraken:''' ''Gene-cult Network:'' For every one Genestealer Brood taken may bestow the Infiltrate special rule to one other Kraken unit. In addition, Kraken units may organize into an "Encirclement Swarm" detachment described below.
**'''Encirclement Swarm detachment:''' This is a primary detachment consisting of the following:
*** 2 HQ (1 mandatory)
*** 3 Elites
*** 3 Fast Attack
*** 3 Heavy Support
*** 6 Troops (2 mandatory)
*** 1 Lords of War
*** 1 Fortification 
:Сommand Benefits: ''Encirclement:'' Units of this detachment with Outflank special rule may enter the field from any table edge (including opponent's one). For each Kraken unit you have in Reserves, you may force your opponent to re-roll one of his Reserve rolls.

*'''Leviathan:''' ''Without Numbers:'' Hormagaunts, termagants, simurghs, rippers, cortex leeches, sky-slashers, gargoyles and Tervigons may purchase Toxin Sacks and Adrenal Glands Biomorphs for half points cost. In addition, Leviathan units may organize into a "Without Numbers" detachment described below.  For every brood of Hormagaunts, Termagants, Simurghs, Gargoyles, Cortex Leeches, Rippers, Tervigons, and Sky-Slashers taken, you may take an additional brood without taking an additional FOC slot; though you must pay for the extra brood as normal.   You may take up to double the maximum number of the aforementioned broods in any formation that permits them to be taken as well as the living tide detachment.
**'''Without Numbers detachment:''' This is a primary detachment consisting of the following:
*** 3 HQ (1 mandatory)
*** 4 Elites
*** 4 Fast Attack
*** 4 Heavy Support
*** 8 Troops (3 mandatory)
*** 1 Lord of War
*** 1 Fortification 
:Сommand Benefits: ''Unending Tide:'' Each time a Hormagaunt, Termagant, Simurgh, Ripper, Cortex Leech, Sky-Slasher, or Gargoyle model is removed as a casualty you gain one Second Wave token, or three from a Ripper or Sky-slasher base's removal. Whenever you have 16 Second Wave tokens, remove them all and place a 10-model Termagant, Hormagaunt, Simurgh, or Gargoyle brood or a three base ripper, cortex leech, or sky-slasher brood with no upgrades into ongoing Reserves.  You may choose to place a larger brood by delaying the introduction of the new brood until you have a larger multiple of sixteen second wave tokens.  Allowing you to place a new 20 model Termagant/Hormagaunt/Simurgh/Gargoyle brood with thirty two tokens, thirty for forty eight tokens, forty for sixty four tokens, or fifty for eighty tokens.   You may also increase the size of a new ripper, cortex leech, or sky-slasher brood accordingly.   Broods introduced into the game in this manner also produce second wave tokens when removed; as do broods spawned by spawning pools and tervigons, or are respawned by formations such as the skyblight swarm.   

*'''Jourmungandr:''' ''Tremor:'' Raveners are Troops by default. Rippers may get deep strike for free. Trygons and Mawlocs may re-roll deep strike scatter.

*'''Gorgon:''' ''Adaptive Evolution:'' Mutation prices are halved (round up). During deployment phase each model in a Gorgon army may replace one of it's mutations with another of the same points cost. If Gorgon is your primary detachment, you must roll a D6 each time one of your units with Synapse Creature rule is removed as a casualty. On a 1 or 2 you lose one Victory Point (to a minimum of 0).

*'''Hydra:''' ''The Awakening:'' Tervigons are Troops by default. All Monstrous Creatures gain Feel no Pain (6+) on the first turn or on the turn they arrive from reserves.

*'''Naga:''' ''Psychic Monstrosity:'' All Naga psykers may re-roll psychic dice rolls of 1 when attempting to manifest a psychic power, and gain +3" to their Synapse range.

*'''Moloch:''' ''City Eaters:'' All non-monstrous creatures gain Move Through Cover (Ruins) and Stealth (Ruins). Any model with the access to Basic Bio-cannons can replace its scything talons with twinlinked flamespurt cannons for free.

*'''Nidhoggr:''' ''Hellspawn:'' If a Flame weapon, or a weapon with the Soul Blaze or Melta rules is used against a Nidhoggr unit, it treats its Strength and AP as one lower than usual (eg: a normal flamer of S 4 and AP 5 becomes S 3 and AP 6). Any model with access to Basic Bio-cannons can replace its scything talons with Stranglewebs for 5 pts. Nidhoggr psykers gain access to Pyromancy and Geomancy disciplines. Nidhoggr armies ally as Come the Apocalypse with other Hive Fleets, but are Allies of Convenience with Chaos Daemons. In addition, Nidhoggr units may organize into a "Giants' March" detachment described below.
**'''Giants' March detachment:''' This is a primary detachment consisting of the following:
*** 3 HQ (1 mandatory)
*** 3 Elites
*** 3 Fast Attack
*** 6 Heavy Support (2 mandatory)
*** 3 Troops
*** 1 Lord of War

:Сommand Benefits: ''Flaming Horror:'' All Nidhoggr creatures gain the Fear special rule. Those who already had it bestow -2 penalty to Leadership for Fear tests against them. Models with 3 or more base Wounds gain Objective Secured while within synapse range.

*'''Chimera:''' ''Adaptable Tactics:'' Enemy models suffer -1 to their reserve rolls for each synapse creature remaining on the table, to a maximum of a 6+. If Deathleaper is your Warlord, your army gains Stealth for the rest of the game. If Old One Eye is your Warlord, your army gains Furious Charge and Fleet for the rest of the game. If the Swarmlord is your warlord, your army gains Preferred Enemy and Hatred for the rest of the game. In addition, Chimera units may organize into a "Divergent Swarm" detachment described below.

:Command Benefits: ''Adaptive Roles:'' Malanthropes may be taken as either a HQ or Elite choice. A Malanthrope must be your warlord, and has the following Warlord Trait:
:'''Digest and Assess''': If an enemy model dies within 6" of this model, the Warlord and all models in it's synapse gain ONE of the enemy model's special rules. In addition, all Codex: Tyranids models in this detachment gain the Preferred Enemy: Tyranids special rule.
:If the only HQs in your primary detachment are Malanthropes, Deathleaper is instead moved to an Elite slot, Old One Eye to a Heavy Support Slot, and the Swarmlord to the LoW slot.
