Plasma coil

A plasma coil is a component of a starship's engines.

Loose plasma coils create large amounts of radiation. Plasma coils are also highly deadly, as an overload often causes computer consoles on the bridge to explode in a shower of sparks, sometimes killing crewmembers.

Fluctuations in the plasma coils can cause a power surge in the warp core. When this occurs, the ship is typically required to take the core offline.
