Something drastic is going to happen to the Void, with the endless addition of primed items, some must go to allow room for new ones. This week will be your last to get Frost Prime, Latron Prime, and Reaper Prime parts from the Void. On March 24th, the Prime Vault will be added to house these parts, and they will no longer be available from the Void. If you have any of these parts now, you will keep them. Cephalon Suda will change their final sacrifice part to Nova Prime Helmet.
This potentially means that there is going to be no more addition void game modes and that the loot tables will stop being even more watered down. Unfortunately, that means void parts will no longer be an indefinite amount of supply.
