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

===Signature Systems===
Also known as relics. Now there's Kroot stuff.  Since you can take a Signature and a Prototype system on the same model, as well as a Warlord Trait, combining multiple synergistic traits can get you a genuine terror on the table.  As an example, the Onager Gauntlet Signature, the Thermoneutronic Prototype, and the Precision of the Hunter Warlord Trait will combine to get you a Commander who's a melee blender that will make mincemeat out of opponents expecting the opposite from the Tau.

*'''Advanced EM Scrambler''': Now restricted to characters instead of some Ghostkeel. Enemies cannot deep strike within 12" of the bearer. Also, in your command phase select an enemy unit within 6"; until the start of your next command phase it cannot benefit from their teammates' auras (except psychic auras). The aura disabling has a range so short you will only rarely use it, so the main purpose is deep strike denial.
*'''The Be'Gel Hunter's Plate''': The bearer has +1 to armour saves and a 5+++. Fun on a shooting Enforcer, so long as you take a SG with it.
*'''Borthrod Gland''': {{W40kKeyword|KROOT}} model only. Once per battle, in your command phase, gain a 6” aura until the start of your next command phase, giving friendly {{W40kKeyword|KROOT}} +1A and +1S.
*'''The Humble Stave''': {{W40kKeyword|ETHEREAL}} model only. The bearer can intone one extra invocation each turn, and gains +1 to its rolls to intone them, turning your nameless ethereal into Aun'Va/Aun'Shi's equal where it counts, yet cheaper (and faster with a hover drone).  If you're taking an Ethereal and you aren't Tau Sept or Vior'la for taking a named dude instead, this is nearly an auto-include, as while the named Ethereals can be taken cross-faction, <s>they disable Tactical Philosophy.</s>  This relic lets you keep their improved invoking for cheaper.
  
*'''Ka’Chak’Tarr''': Enhances a Shaper Kroot Rifle into 24" Rapid Fire 2 S5 AP-2 D2, plus ignores Look Out Sir, and 6s to wound cause a mortal wound.
*'''The Kindled Blade''': {{W40kKeyword|CADRE FIREBLADE}} model only. Once per battle, in your command phase, gain a 6” aura until the start of your next command phase. Friendly {{W40kKeyword|<SEPT> FIRE WARRIOR TEAM}} units in the aura autopass morale tests. ''The Yawn Blade''.
*'''Multi-sensory Discouragement Array ''': At the end of your movement phase select one enemy unit within 12" and roll 3d6. If it's higher than their Ld, that unit is debuffed until the start of your next movement phase. Since the roll happens before the shooting phase, you can either commit or JSJ your Commander away. Select one of the following effects:
**The unit loses obsec.
**Halve the move stat and charge rolls of the target.
**The target's ranged attacks can only target the closest eligible target.
*'''Neuro-Empathic Nullifier''': {{W40kKeyword|ETHEREAL}} model only. Once per battle, in your command phase, select one enemy unit within 18" of and visible to the bearer and roll a D6. On a 2+, until the start of your next command phase that unit cannot perform actions and any current action fails.
*'''Ohr'Tu's Lantern''': Replaces a markerlight only with a high intensity one. When this model performs a Fire Markerlights action, roll five additional dice.
** Rather useful for pathfinder-light lists to put on Fireblade. Beware that you can't split individual model's markers, so this is got lighting up something whole army plans to unload at 
* '''Onager Gauntlet''': {{W40kKeyword|Battlesuit Commanders}} only. It has finally become a proper S12 AP-4 D3 weapon you can do all your attacks with.
* '''Puretide Engram Neurochip''': While the bearer is on the battlefield, each time you spend a CP to use a '''Battle Tactic''' or '''Epic Deed''' stratagem, regain that CP on a 3+. Many strats are in those categories, so make sure you've studied the list so you can competently choose this relic or not.  It's hard to argue with, but then again, you can generally use an Ethereal as a CP battery on your own turns, reducing this relic's utility.
*'''Solid-Image Projection Unit''': 4++ (''meh''). Also the first failed save ''every turn'' gets turned into D0 (the characteristic, not the damage inflicted). Useful to foil snipers (unless they manage to inflict their mortal wounds) and can buy a character time to run away from melee.
** Arguably an auto-take on either this or begel plate for tough as nails commander who wants to take 4 guns (as this is better than shield-Gen)
