Demolitions is the controlled application of violence through chemistry and
physics. It covers breaching charges (shaped plasma, cutting torches), IED
construction and disarmament, ship-to-ship demolition, unstable ordnance
handling, and the art of putting exactly the right amount of explosive in
exactly the right place. Legion breachers, Operative demolitionists, and
Rim saboteurs all depend on this skill. The margin between a clean breach
and a collapsed corridor is measured in grams and milliseconds. Trained
only: an untrained character near live ordnance is a liability to everyone.

Notes
Special: Setting a shaped charge grants +2 to the breach roll on the target. A
failed disarm by 5+ detonates the device; failures by less than 5 merely
fail to disarm safely (retry possible).

Untrained: Cannot reliably set or disarm explosives. Any untrained disarm attempt
risks detonation (DC 10 flat check on failure). Setting charges untrained
is possible but at -4 and with no shaped-breach bonus.
