Lex Proxima Packed with Energy Ascendency question

I am considering taking this Ascebdebcy notable in that map region but am wondering how long the increased damage and movement speed last for when opening a chest or Sulphite Vein, and if they last the entire map instance, do they stack up? Thanks in advance :)

p.s. I looked all over the internet to find the answer to this but couldn't find anything relevant.

I was also wondering what the passive means when it says "for each voltaxic sulphite vein or chest". What is a voltaxic sulphite chest?

Ye I was wondering about that myself as all I've ever seen were piles of sulphite on the ground to click on. Maybe I just never took the time to read it properly lol

Sometimes they spawn as chests instead of piles, typically indoor building layouts.

And yes, they do stack for the entire map, and right now the calc seems bugged, so that the speed boost is pretty insane if you manage to hit more than two.

They last the entire map, and yes it stacks.
It's definitely worth it if you're a delver.

Or if you're into Chayula Rotas, as a way of sustaining your regular counts of those breachstones, you could theoretically run 100% delerious T16 Park maps x5 breach delerium orbs with guilded Breach Scarab while running Packed with Energy with Niko just for the buffs to MS/dmg, not to mention the craftable watchstones to boost it even more with sextants and beyond Zana mods etc. like a hot knife through butter and wouldn't need every bit of BiS gear upgrades, which is kinda nice :)

p.s. notice I said Theoretically :P
