Oneshot

Description
Oneshot can be found on a small number of area-attacks on the MUSH. Primarily it will be seen as part of the bombs created by Demolition. Certain special FCs may also have it, in addition to plot devices or other objects.

The purpose is, it will allow the Area attack it is attached to to attack any number of targets and only consume a single Ammo

Strategy
You probably don't have one. If you do, it's probably attached to one of your fancy bombs, and will automatically allow the bomb to target any number of targets regardless of the bomb's limited ammo (1 ammo would normally only target up to 3 targets)
