Calimshite Mirror

Calimshite Mirror:
An ancient theory brought into modern use. This mirror is seven feet tall and four feet across. Concave in form, it is mounted such that it can capture sunlight and, in bright conditions, can focus the sun’s heat into a ray that is especially damaging to enemy ships sails and rigging. Though it is clumsy to aim and reliant on the weather, should it be brought to bear against flammable materials, its effect is quite devastating.
