Can read up
here. Basically, you get capped VW lights during the campaign and you can spam bosses to your hearts content for fast kills/hmp/riftstuff. "Lights" are basically what gives you the enhanced rewards in VW. Since lights will always be capped, you don't have to worry about procing the NM for improved treasure (you can still trade rubicund cells).
You can join a group and semi afk clear box spam, or displacer and solo a bunch of Aellos or whatever for your own HMP. The campaign starts tomorrow, which is perfect timing to start collecting. You don't have to do anything to activate it, it's always active during the
listed timeframe.

Voidwatch
Voidwatch Campaign
When this Monthly Adventurer Campaign is active, every Voidwatch battle starts with alignments at the maximum level.
White proc is still possible to perform but it is already at 100%, so it is suggested to complete the Voidwatch Quests and easily obtain all of the Voidwatch Key Items during this campaign.
It is still possible to increase the four alignments by an additional 150% after using the following cells: Cobalt Cell, Rubicund Cell, Xanthous Cell, and Jade Cell.
Note: The battlefields that take place in Provenance are not eligible for this campaign.
Note: There is no reason to take your time on kills during this campaign. It is recommended that you team up with other players, and take advantage of Phase Displacers to kill the NMs as quickly as possible. This will expedite your number of kills, thus granting the highest amount of loot and Empyrean Weapon upgrade materials.
