ik hep geen ladder

long journey but completely worth it

i only wish their was an Adept version of the armor when you go back though and do it on a + playthrough, take my advice and dont worry about doing it all over again if you already have it

i already did it

All I found after breaking the stalagtites is a can of soda. I referenced the map and I was exactly where the map you provided shows. There were two crates of goodies but no power cell.

do i need all 5?

The armor is totally worth it. Completed this quest last night.

FOR THOSE WHO CANNAE FIND THE LAST POWER CELL:

At the beginning of the mission you go up a ladder to Sylens' workshop, then you go down an elevator shaft. Right after that you will rappel down. The quest marker will tell you to go right, instead go LEFT. There you will see a yellow climbable on your left hand side, it's a bit annoying to get to, use the rock nearby. Climb all the way up, get into the corridor/cave and at the end you got your sweet, sweet power cell.

You can also do it close to the end of the quest as the zip-line after meeting the Alphas drops you off quite literally in front of the aforementioned handhold.
I still had to watch a yt video before I got it but oh well. Now I can restart another new game+ at max level with the weaver :)

cell 4: instructions not clear enough

You kidding? You restore power and the cell right after it. How's that not clear?
