The Stasis Bomb is an archaic holdover from the Age of Technology, and is deployed by the deadly and much feared aircraft known as the Ravenwing Dark Talon that is a part of the armoury of the Dark Angels' elite 2nd Company, known as the Ravenwing.
In the workshops of The Rock, the Chapter's Techmarines labour lovingly over the construction of each bomb, using a STC template dating back to before the founding of the Imperium of Man that they have repeatedly denied owning to the Adeptus Mechanicus.
The blast of a Stasis Bomb causes a degree of damage but, more importantly, will momentarily halt the flow of time.
While the actual suspension of the normal flow of the space-time continuum is measured in mere milliseconds, this unnatural disruption to the time stream has lingering effects on those in close proximity to such a blast, causing gut-wrenching disorientation and slowing their reaction times.
