Mass Effect (Shadowrun 4th ed)
The unstable dark matter energy fields used to create biotic effects can sometimes violently react with each other. Sustained biotic powers such as lift or singularity can react to spatial distortion effects such as warp to create a powerful explosion.
Treat as explosion with damage equal to the combined force of both powers. Damage is reduced by -2 per meter.
