Current max level for hidden potential

[ZeGoose]

See title. Teammates told me that you can get to level 5 so I tried using my vraolet. I was already at 3 and now +10 again but I can't get to level 4. Do I have to get the lambda version?

You can only go to 3.

Is that the current max level right now? Or because of the weapon?

It's the current max level right now. Nothing can go to 5.

Alright thanks.
