The Sonic Screwdriver
The Doctor's all purpose tool
Carried by The Doctor
An alien form of techno-wizardry relying exclusively upon psionic interactions. A psychic interface allows anyone to attempt to use the device, even non-psychics, but without investing I.S.P. into it the chances of it being used successfully drop drastically. After a certain amount of exposure to the device, depending on the amount of psychic energy in the user, these requirements can be reduced or circumvented completely.
When physically manipulating its target, the Screwdriver projects a directed wave of subtle sonic vibrations which can typically penetrate most material, unless it is extremely dense (SAMAS MDC or greater). When psychically manipulating its target it does so with pure psionic energy.
The Sonic Screwdriver has some other limitations as well, for example when using its telekinetic or telemechanic abilities on a target of a type that it has not encountered before (or been pre-programmed for), it has a -50% penalty to its success ratio. Once The Doctor or another Time Lord (not just a Gallifreyan) has reconfigured it (requires 1D4x10 minutes, and must have a complete understanding of the nature of the target) this penalty can be ignored. A quick-fix version of this can be attempted in just 1D4 minutes, assuming some part of the nature of the target is understood, but only reduces the penalty by half.
Using the Sonic Screwdriver requires 1D4 Actions, or 1D2 for The Doctor.

The sonic screwdriver — often called the sonic — was a highly versatile tool used by many, but not all, incarnations of the Doctor. The Doctor modified and ostensibly upgraded it over the years, giving it an increasing number of applications. Early versions were used mainly for the picking of locks and for projecting sound so as to, for example, detonate bombs. By the time of the Ninth Doctor, the sonic was able to also be used as a sophisticated scanning device, with medical applications. Subsequent incarnations gave it even wider functionality, such as the ability to hack into computers, provide geolocation and actively defend against some types of assault weapons.
