Garde tum, im stuck

[Moon Shoes]

Im in the area Garde tum and I understand that I have to find four switches/activation crystals but I cant find 2, one of which i can see but cant reach with the bow or gun as its just a hole in the ceiling with a crystal to the right. The last one I have no idea where it could be. Ive been serching for a good hour on how to get through

For the one in the ceiling, you need The Swarm (It's an Energy weapon you'll find in the same area). I imagine the fourth one is the one at the top of the unuseable lift. To get it you have to wait a while for a ladder-lift, let it take you to the top of the shaft and it's on the top left of it. That's also the area with the gate the four switches open, and the second tome for Bysurge.

You don't need to find those to progress in the area. When you look at the map of the area note that there are pathways that aren't obvious. Run into walls and you'll find hidden passageways. Those 4 switches you're looking for are for loot I imagine. Haven't found them all myself yet.

how do u use the swarm to hit the switch ? Been trying but its not easy.

The four switches are bonus content, not required to get to the boss (although the 2nd boss journal is near there): It's the 2nd Gaian Relic
