For kicks. Just thinking of movie monsters like Jason who are always right behind you no matter how far you run, or S.U.V.s that can plow over rocks and mud. Anyways, right to the meat of it:
Conditioning: (1CP) This minifig is used to carrying heavy loads into combat situations. It ignores the first inch of movement penalty caused by carrying equipment, bricks, etc.
Extreme Conditioning: (3 CP) This minifig is truly hearty, like a pack mule. It ignores the all movement penalties caused by carrying equipment, bricks, etc.
Ponderous: (1CP) This minifig moves slowly, yet steadily. Its speed is reduced by 1" permanently, but it ignores all movement penalties from terrain or enemy effects. It may be rendered completely immobile, however.
Implacable: (3 CP) This minifig is a force of nature, utterly unstoppable by conventional means. It ignores all movement penalties from terrain or enemy effects. If immobilized, it may still move up to half of its original speed.
It's a secret to everybody.
