Thermo-Booster
The razorback is an animal that is reputed for its strength and its surprising vigor. Since several years the alchemists of the Ægis have been trying to improve on this. Their new thermo-booster, if it is installed correctly in their mounts' armor, should allow these animals to overtake the fastest of stallions!
A fighter who already has steam equipment that affects MOV cannot be given a thermo-booster.
Every fighter of Tir-Nâ-Bor with RES 10+ and a razorback (armored or not) in his equipment can be given a boiler and a therm-booster / MOV for +5 A.P. This is a piece of equipment and not an artifact.
Dogs of War: The boiler and the thermo-booster are attributes.
Rag'Narok: A Unit in which all members are equipped with steam equipment / MOV only makes one Pressure Roll for its MOV bonus. The result applies to all members of the Unit in question.
This modification is considered to be printed on the fighters' reference cards. The miniatures may be customized to represent this additional gear.
