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

===Cerastus Knight Atrapos===

This is your answer to any superheavies in your way.  It gets Twin-Linked against Superheavies or Gargantuans, and considering that one of its weapons is a Strength D Lascutter that can be fired at short-range or in combat and it is a freaking beam weapon 8" line of pure death, it WILL see use, even if it's just to break buildings because of Wrecker.  And the other gun, oh, it's just a Graviton Singularity Cannon which is a S8 AP2 large blast, has Armorbane and Concussive. Also, you roll a d6 before firing that singularity - a 1 means you lose an HP, a 6 turns this singularity into a goddamn VORTEX. On top of that it has 7 HP, IWND 6+ and a Ionic Flare Shield meaning anything not D or haywire can fuck off and die. 

All considered, this is a 0-1 option for every 2000 points in this army because you seriously don't want to be on the wrong side of this thing's gun.  For these reasons, throwing him in as Actueller or as an Arbalester would probably be the smartest move as those would make the most use of the vehicle-demolishing weapons.
