Editing Warhammer 40,000/9th Edition Tactics/Tyranids (section)

===Universal Biomorphs===
These upgrades grant the following ability and some gain the keyword of the same name as the upgrade.

*'''Acid Maw''': Gives the keyword that lets you access a 1CP stratagem to spit acid on your enemy to inflict mortal wounds. On the Carnifex it's one of the options for the head but you're probably better off with Tusks or Enhanced Senses.

*'''Adrenal Glands''': Adds 1" to the move characteristic and +1 to strength characteristic of the unit. '''This is amazing'''. Combine with {{W40Kkeyword|Kraken}} and movement boosting Stratagems, and that seemingly small bonus can make a big difference.

*'''Biostatic Rattle''': One of the tail options of the Trygon/Mawloc, you select an enemy unit in engagement range and if you roll higher than their leadership on 3D6 you shut off re-rolls for their hit and wound for that turn. Remember that the average roll of 3D6 is 10.5

*'''Chitin Thorns''': Improves the Ap of Melee attacks by 1, useful against Armor of Contempt.

*'''Enhanced Senses''': The bearer's BS becomes 3+, one of the options for the carnifex head and the one you want if you're aiming for a dakkafex or thornback.

*'''Extended Carapace''': Gives M7" and a 4+ armor save to genestealers, now that they are infiltrators this could work for making them survive longer.

*'''Flesh Hooks''': Gives the keyword and lets you ignore the vertical distance when you move, advance, or fall back.  The keyword also lets you access a 1CP stratagem to give +1 to your melee hit rolls for attacks against non-VEHICLE and non-MONSTER enemy units.

*'''Infestation Node''': An upgrade for a Genestealer unit that makes you put a marker down with them that regenerates D3 destroyed models a turn. The marker is removed if there are enemy models within 3" at the end of any phase and there aren't any friendly units with them.

*'''Lash Whip''': Gives the keyword and lets you re-roll 1's to hit in the fight phase for models with this biomorph. Found on those who take a single bonesword.

*'''Prehensile Pincer Tail''': Lets you re-roll one hit roll or one wound roll each Fight phase, useful for a Flyrant with the Reaper.

*'''Spore Cysts''': The bearer counts as in light cover against shooting attacks, one of the two back options for the carnifex, you should always take this if you can.

*'''Toxin Sacs''': Hit rolls of 6+ by the model/unit in the Fight phase automatically wound. Best used on models with low Strength.

*'''Tusks''': Gives the {{W40Kkeyword|Horned Chitin}} keyword, useful on a Carnifex that aims for the big guys on the board.
