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.
Stasers had both lethal and non-lethal settings, and fired an unspecified type of directed energy. They were relatively non-damaging to inorganic matter but caused massive tissue disruption to living creatures. (DW: The Deadly Assassin)
- As a result a single staser shot could apparently kill a Time Lord outright and ensure that regeneration could not take place.
A Staser rifle was used in the assassination of the Lord President by Goth. (DW: The Deadly Assassin)
A staser wielded by Commander Maxil was used to stun The Doctor. (DW: Arc of Infinity)
Stasers were ineffective against Sontaran armor. (DW: The Invasion of Time)
The Un-named 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. (DW: The Five Doctors), however it is implied that he was murdered and the staser placed on the body.
The visual effect of a staser bolt varies, and has been observed as a white flash at the victim, a green lance, or a green-white beam that cascades over the victim's body.
