Editing Warhammer 40,000/8th Edition Tactics/Tyranids (section)

====Universal====
*'''Miasma Cannon''': Replaces a heavy venom cannon. Compared to the heavy venom cannon, it gains the ability to auto-hit anything within 8", and always wounds non-{{W40Kkeyword|vehicles}} on a 2+. 
** Effectively Hive Tyrant only, as it's the only character that can take a venom cannon to start with, and should always be paired with Wings so you can get into auto-hitting range faster. 
**Better than the basic version against T5+ non-{{W40Kkeyword|vehicles}}, and of course against anything within 8", but not nearly as good as a Venomthorn Parasite in general, due to the Hive Tyrant's already good BS and the fact that the Venomthorn is like a *1.5 multiplier, which would require at least a T10 target for this to meet or a T18 one to beat, and good luck finding those.  Don't take this unless you've already handed out a Venomthorn.
*'''Reaper of Obliterax''': Replaces a lash whip and bonesword or the monstrous version. Same stats as the normal one, but on a wound roll of 6+ it doubles its damage. With Toxin Sacs on the monstrous version, that's a whopping 7.
** Because this upgrades a weapon that isn't free, cost matters, but the strength of the underlying weapon really doesn't, since the special ability triggers only when you're definitely wounding regardless of strength. As a result, this is actually best on a Behemoth Warlord (for more damage) or Gorgon (for more reliability) Tyranid Prime; the difference is clearest in the Behemoth case, where you're spending 102 points minimum on WS2+ A4 S5 AP-2 D1, increasing to D4 on 6s, as opposed to 158 minimum on WS2+ A4 S6 AP-2 D3, increasing to D8 on 6s.
*** Note on calculating damage: Because of the order of operation, the damage is first multiplied. After that, you add the extra damage. So you are 'just' dealing 8 damage at max. Nevertheless, if you want something dead, use Adrenaline Surge for attacking a second time or Voracious Appetite to increase the chance of dealing high damage.
*** Just an idea: Give this to a winged Hive Tyrant with adrenal glands, toxin sacs and the '''{{W40Kkeyword|Behemoth}}'''-Warlord Trait. You get a high chance for a Turn 1 Charge and the opportunity to kill the enemies bigger threats - for example a Land Raider or ,if you're lucky, a superheavy
*'''Ymgarl Factor''': It's back! at the beginning of each fight phase, randomly gain +1T, +1A, ''or'' +1S. The stat returns to normal after the fight phase. 
** Generally not worth it, due to its random nature and the fact that it only last a fight phase - you have only a 2/3 chance of rolling a stat that might help you kill things better in melee, and if you roll strength, it might do nothing at all.
***This and the Norn Crown are the two Relics that don't require any existing equipment. If your warlord has an odd loadout, or is a Zoan, this can be a good Relic just because of a lack of better choices. 
*'''Maw Claws of Thyrax''': Enhances a model equipped with rending claws or monstrous rending claws. If you slay a model in the fight phase, you can re-roll ''all'' failed to-hit rolls in melee for the rest of the game.
**Because monstrous rending claws are ''cheaper'' than rending claws, absolutely superb on a Hive Tyrant.  (An odd statement given that MoRCs are only available to Broodlords &  Tyrants which are considerably more expensive than a Prime + RCs, lol, but the point stands.)
**Overkill on a Broodlord, rerolling ones only after a successful fight is not worth.
*'''Norn Crown''': Models within 30" do not suffer the penalties from Instinctive Behaviour. Probably the weakest choice here, but could be useful if you don't plan on using many synapse units (e.g. you run Hydra and want to save your Troops slots for more Gaunts).
**Note that it doesn't grant immunity to morale, like synapse would, so really only useful on units that have no moral issues (like single model monster units). Main value is if you need to space out your giant ranged bugs, but don't want to take penalties when shooting at further targets. The Tyrannofex's rupture cannon, for example, has 48" of range, but he's only BS5+ if he's not in synapse and not targeting the closest unit.
