Go to the Top of the Drumroot
Follow the path up the mountain until you reach the giant cavern. Dive underwater and follow the tunnel to reach another section of the cavern. Near where the water is, you’ll find Vaus. Collect his seeds then continue following the tunnel. Deal with the machines blocking your way then use your focus to find the grooves to climb up in the cave. Continue heading for the top. Along the way you can find a Greeshine Sliver. Eventually, you’ll end up the giant cavern. Make sure to drop down the ladder in case you fall to make it easier to get back up. Jump to the rocks in the center of the room heading to the southern side. There will be a grappling point you can use to get on the ledge. Follow the path around to end up on the giant rock in the middle of the room. From there, jump to a grappling point on the east side. Climb up the cave wall near the waterfall to reach the top.
Gather 6 Widemaw Metal Pods
Head southwest to find the Widemaw and follow behind it. It will shoot off the pods. Be sneaky as you collect them so it doesn’t spot you!
Return to Kue
