Each particle only lasts for a single hit, regardless of the arcane's duration. Each hit you take removes 1 particle, so enemies that hit rapidly like a Grineer Heavy Gunner, can easily strip all 6 particles near instantly.

The damage reduction does stack with each active particle. So 1 particle is 12.5%, 2 particles is 25%, 3 particles is 37.5%, 4 particles is 50%, 5 particles is 62.5% and 6 particles is 75%.

But again, since you lose a particle with each hit you take, in order to maintain 75% damage reduction, you would need to immediately enter void mode for 3 seconds (at max rank) instantly after taking a single hit. Combined with the particles decaying over time as well, you would need to constantly refresh them.

Taking 18 seconds in void mode for a "full refresh" which will last 22 seconds before the first particle will vanish, assuming you don't get hit before then. They also continue to decay while in Warframe mode, so switching to maintain stacks does not work. They also do not affect your Warframe either from the looks of it.

It's really good if you know you're going to take a single, big damage hit in operator mode, since you can reduce its damage by 75%. On the other hand, if you know you're going to take a single big damage hit in operator mode, void mode grants 100% damage reduction and doesn't require 18 seconds of setup, 100,000 Vox Solaris rep and an arcane slot.
