Singularity

Singularity is an biotic ability available exclusively to Adepts and the Asari Scientist in Mass Effect, and Adepts in Mass Effect 2.

According to Mass Effect: Ascension, a singularity is generated when a biotic uses dark energy to imbue a subatomic particle with infinite density. This profoundly warps the fabric of space-time, causing all mass within the singularity's event horizon to be drawn into it. Creating and sustaining one is extremely difficult, requiring advanced training as well as considerable biotic talent.

Mass Effect
This gravitational power sucks multiple enemies within a radius to a single area, leaving them floating helplessly and vulnerable to attack. It can also attract objects from the environment, such as crates or pieces of furniture; enemies will take damage if they collide with other solid objects in the Singularity field.
