Captured Huyblein Tower and the two other uncaptured portals up on the mountain on the way home. I didn’t have any resonators, so I just hung around hacking until I had enough to complete the tower and get the portal key. I can keep recharging it from ground level at work (which is nearly directly below the tower on the floor of the river valley) until I get enough L4/L3 resonators to make it as strong as I can at the moment, then head back up.
