Selective Compression
The Thermo-Priests know that the power furnished by their boilers weakens when they are linked to multiple machines. To solve this problem, they have developed circuit breakers and special pipes that are activated by Magic of the Forge. With Selective Compression the Thermo-Priest can direct steam towards one hydro-pneumatic circuit rather than the other. Thus a figurine equipped with a boiler, having multiple connections, will see the power of one of his apparatuses grow at the expense of the others.

The target's figurine can only use one of its steam apparatuses, but can roll as many dice for the Pressure Rolls as it has steam equipment. For example, if it has two, it must choose one of use but rolls two dice and adds the results. A result of 1 on any Pressure die still indicates an incident.
Selective Compression can only be cast during the Magician's activation and its target must be a Dwarf of Tir-Nâ-Bor carrying steam equipment.
