Deathgates

From A Wheel of Time Wiki

A weave of the One Power using Spirit, Earth, and Fire that opens and closes Gateways very rapidly. Any Shadowspawn that pass through these Deathgates die because they are constructs, and cannot survive such a trip.

Along with Arrows of Fire and Fire Blossoms, Deathgates are a recently rediscovered combat weave used by the Asha'man. These weaves were shown Rand when Lews Therin gained control of the One Power in Knife of Dreams.
