Stasis Grenade

A Stasis Grenade is a unusual Imperial weapon that can create a stasis field effect. Developed by the Adeptus Mechanicus, Stasis Grenades are extremely rare and expensive to acquire. This and their specialised nature means their issue is limited to only special agents of the Imperium rather than common soldiers of the Astra Militarum or even the Adeptus Astartes.

On activation, the grenade emits a stasis-loop field around itself. Everything within the field exists in the same moment of space-time repeated over and over. Eventually the grenade's power source is expended and the field collapses. As the grenade's power source is small, the stasis field caused by an activated Stasis Grenade does not normally last for a long period of objective time, though the duration is long enough to cause a significant amount of battlefield disruption for those caught within the projected stasis field.

Since they are rather bulky and possess delicate internal mechanisms, it is not possible to fire a Stasis Grenade from a Grenade Launcher. Instead, they are typically deployed in a manner similar to Melta Bombs.

Game History
Stasis Grenades were originally made available during the 1st Edition of Warhammer 40,000, but they are not a current wargear option for any Imperial faction. They are used in some in-universe fiction, however.
