Hekaton siege claw with twin-linked rad cleanser

Weapons and attacks with this special rule may reroll failed Armour Penetration rolls against fortifications and immobile structures (such as bunkers and barricades), and add +1 to any result rolled on the Building Damage chart. If this attack damages a bulkhead or wall section of terrain and destroys it, remove that section of terrain from play if possible.

A model which loses one or more wounds to an attack with this special rule and survives has its Toughness value reduced by -1 for the rest of the battle.
