Also known as your relics. Please note that you cannot give any of these to Kroot units. Although why you would ''want'' to give a relic to a Kroot Shaper is beyond me. 

* '''Puretide Engram Neurochip''': Once per battle, you can re-roll a single hit roll, wound, or damage roll made for the bearer or a friendly {{W40kKeyword|<SEPT>}} unit within 6" of the bearer. In addition, if your army is battle-forged and the bearer is on the battlefield, roll a d6 each time you or your opponent use a stratagem, on a 6 you gain a bonus command point. The first ability isn't amazing, per-se, but it's not bad and it might help you out of a jam. The second ability is far more worthwhile if you expect your opponent to spam low-cost stratagems, giving you plenty of chances at bonus command points.
** RAW this ability triggers during deployment or other pre-game phases as long as the bearer is already on the field, so deploying the bearer first against armies dependent on deployment/infiltration strategems can pay off in a big way.
** This relic is all but guaranteed to pay for itself, assuming you spent 1 CP to take it and reasonably expect to spend at least 1 CP on a reroll during the game. And that's not even accounting for the CP you generate from it.
* '''Onager Gauntlet''': {{W40kKeyword|Battlesuit Commanders}} only. The old donkey punch is a single S10 AP-4 d6 D attack in melee ideal for cracking open tanks, but you only get one attack and a WS of 3+ really hurts your chances of actually killing anything with it.
* '''Multi-sensory Discouragement Array ''': Enemy units within 6″ subtract 1 from Leadership. Skip.
* '''Solid-Image Projection Unit''': {{W40kKeyword|Ethereal with hover drone}} only. Once per phase, if declared as the target of a charge, the Ethereal can move up to 3″ before the charge is made. Amusing, but if something is trying to charge your Ethereal, he's dead meat anyway. Save your slot for something useful. *Insert Dr Zoidberg sound*
* '''Seismic Destabiliser''': At the start of each shooting phase, you may either pick an enemy Infantry unit claiming cover or a Building within 12″ of the bearer; the Building suffers D3 mortal wounds. If targeting the infantry squad, roll a die per squad member. On a 6, they suffer a mortal wound. Might be decent for weakening blobs, but you've got better choices. Against a 30 model Boyz Mob, its about 5 dead Orks--however, most large units are barreling forward and not in cover. 
* '''Supernova Launcher''': Replaces an Airbursting Fragmentation Projector. 18″ Assault D6, S6, AP-2 2D. can shoot targets that are out of line of sight. Good for pot shots on hidden primaris and the like.
