Staser

Staser weapons were the standard armament of the Chancellory Guard on Gallifrey. The Guards were normally equipped with staser pistols, although staser rifles were also occasionally used.

Usage

Stasers had both lethal and non-lethal settings, and fired an unspecified type of directed energy. They were relatively harmless to inorganic matter but caused massive tissue disruption to living creatures. The corpse would be unrecognisable upon examination. (TV: The Deadly Assassin) The sidearm of the President's personal security did not have a stun setting. (TV: Hell Bent)

According to one account, a single staser shot could kill a Time Lord outright and ensure that regeneration could not take place. (PROSE: The Ancestor Cell) However, using the sidearm of the President's personal security, the Twelfth Doctor shot the General once, triggering the General's regeneration. (TV: Hell Bent)

Stasers were ineffective against Sontaran armour, (TV: The Invasion of Time), androids of Kraal manufacture, (AUDIO: The Oseidon Adventure) and Daleks. (AUDIO: The Apocalypse Element)

Staser pistols apparently come in different versions. Those seen after the Sontaran invasion were significantly larger then those seen before.

The stasers issued to Chancellery Guards and to security personnel were coloured red, but Castellan Spandrell and Chancellor Goth both used black pistols. (TV: The Deadly Assassin)

Before his death, Andred showed his wife Leela how to operate a staser. (AUDIO: Extermination)

Stasers were used during the Last Great Time War. Children in the First Segment of the War sorted out staser bolt chargers in munitions factories. (PROSE: The Stranger)

Instances of use

A staser wielded by Commander Maxil was used to stun the Fifth Doctor. (TV: Arc of Infinity)

A Castellan supposedly kept a small staser hidden on his person, and was shot dead by security personnel whilst using it to attempt an escape during Borusa's Death Zone gambit. (TV: The Five Doctors)

A staser sniper rifle was used in the assassination of the Lord President by Goth. (TV: The Deadly Assassin)

Coordinator Narvin was given a staser for a mission in Earth's past. President Romana forbid him from using it to stun or kill humans. He shot a wall to impress the local people and he promised to gift it to Sol in exchange for her help. (AUDIO: Intervention Earth)
