The Discouragement Redirection Cube was added to Ichun's portal gun mod as of 1.2.5v1. It serves as a way of redirecting thermal discouragement beams. It will also, like the Weighted Storage Cube or Weighted Companion Cube, weigh down plates. It can be picked up using a portal gun or the G key.
They can be dispensed automatically by a Discouragement Redirection Cube Vent.
It may also be referred to as the "Weighted Pivot Cube".
