Editing Warhammer 40,000/Tactics/Questoris Knight Crusade (30k) (section)

===Questoris Knight Paladin===
Your basic Knight with a "Questoris Battle Cannon", which unlike the 40k counterpart is a Strength 6, Ordnance 3 weapon, but it can be replaced with the more familiar (and higher strength) Rapid-Fire Battle-cannon for free.

Its 2 Heavy Stubbers may also be upgraded to Bio-Corrosive Rounds which reduce its range by 6" but grant them the Poisoned special rule, making them a "bit" more of a threat against high toughness units (such as Primarchs or Monstrous Creatures), but mostly this has no significant impact vs MEQ... and it has its Reaper Chainsword for hitting things with. 

Both types of cannon are the general purpose weapons that fire multiple AP3 large blast templates and are Ordnance, meaning it gets several chances at trying to penetrate vehicle armour. In particular, the Questoris cannon is also very good at wiping out large units of enemy soldiers (I'm looking at you Legion Marine squads.) But for more general uses switch to the Battle-Cannon instead since it does better against vehicles,

While the Chainsword is entirely overkill against most things, you're better off with the stomp attacks unless you are fighting a superheavy, monstrous creature or high value enemy warriors such as Primarchs. But you get both Stomp Attacks and chainsword anyway, so you're very likely to chew things up in melee, just be aware of what your opponent is bringing against you. 

Questoris Knights may also be upgraded with Occular Augmetics which grant Night Fighting but the epic ability to re-roll 1s on Vehicle damage tables AND on Destroyer tables so long as the target was within 12", meaning death to things struck by your <s>sword</s> ranged weapons only.

Paladins make decent Knights for pretty much any Household rank.
