Fringes of Space
Frequently used for demolitions work and in boarding actions, proton grenades are extremely powerful devices that rely on the same technology as the warheads of photon torpedoes, albeit on a much smaller scale. Nevertheless, proton grenades are exceeded only by Thermal Detonator for sheer destructive power in a hand-held package. Proton grenades feature a magnetic clamp and directed charge, so that they are better suited to breaching bulkheads or destroying facilities than as anti-personnel weapons. The devices are also highly prized in demolitions work because of the sympathetic qualities of the blast. Multiple grenades correctly linked together produce a much more powerful blast than each grenade separately.
When setting up an explosive device using proton grenades, the second grenade adds +20 damage, the third adds +30, the fourth adds +40 and the fifth adds +50, for a a total of 150 damage for 5 grenades. After the fifth grenade, additional grenades do not add additional damage, but do increase the blast range by one range band per addition grenade.
