Earthwake Revelation and hidden Alpha caves
Infusing 120 Lumin Amber into the Breezy Plains branch clears the vines off hidden caves. This guide also covers the boulder and dark rock in front of the Minespine cave.
The short version
- Infusing 120 Lumin Amber into the Breezy Plains branch unlocks Earthwake Revelation, which opens previously hidden caves by clearing the vines that block them.
- Lumin Amber comes from environmental puzzles, mini-games, time trials, Sanctums and general exploration, and catching a Lumin Amber-blessed Aniimo gives you its Lumin Amber.
- Hidden caves can sit behind cliffs and waterfalls, so check those spots once Earthwake Revelation is active.
- Alpha Geoclaw is in the Nimbus Fields, in a cave revealed by Earthwake Revelation, reached by the stream and lake to the west of the Breezy Plains branch.
- The Alpha Minespine cavern needs an Aniimo with the tunnel ability, such as Budclaw, to get under a boulder, and the Minespine cave needs Gravity Pull to push explosive barrels onto dense dark rock.
Some of the best caves in Aniimo stay out of sight until you do something about them. A few are covered in vines. Others sit behind a boulder or a wall of dark rock. Alpha Geoclaw and Alpha Minespine both live behind obstacles like these, and so does the Minespine cave.
Vines are the most common obstacle, and you fix them with Earthwake Revelation. You unlock it with Lumin Amber, so most of the early work is collecting that. The boulder and the dark rock each need a different tool, which this guide covers further down.
Unlocking Earthwake Revelation with Lumin Amber
Earthwake Revelation unlocks when you infuse 120 Lumin Amber into the Breezy Plains branch. Once it is active, it opens previously hidden caves by clearing the vines that block them.
That is all it does, but it matters. A vine-covered entrance is easy to walk past without noticing, and until you have Earthwake Revelation you cannot get through one anyway. If you have been circling an area sure there must be more to it, this is often the reason.

Lumin Amber to unlock Earthwake Revelation
Where to get Lumin Amber
Lumin Amber is a collectible resource spread across the open world. You pick it up through exploration, environmental puzzles on the map, mini-games, time trials and Sanctums. Sanctums have their own guide on this site, so all you need here is that they pay out Lumin Amber too.
The source people tend to miss is catching. Some Aniimo are Lumin Amber-blessed, and when you catch one, its Lumin Amber goes to you. That means a catching session can count toward Earthwake Revelation as well, so keep an eye out for blessed Aniimo while you explore.
Finding the hidden caves
Hidden caves can be tucked behind cliffs and waterfalls. Those are the places to check after you unlock Earthwake Revelation. A cliff face or a waterfall you passed earlier may now have an entrance behind it where the vines used to be.
Alpha Geoclaw in the Nimbus Fields
Alpha Geoclaw is in the Nimbus Fields, inside a cave that Earthwake Revelation reveals. To get there, head for the stream and lake to the west of the Breezy Plains branch. That is the same branch you fed the Lumin Amber into, so you start from familiar ground.
The path to the Alpha Geoclaw is not clear all the way. There is an obstacle along the route: past the hole you will find a Lumberer and a growth that blocks the way. Expect that stretch rather than assuming the cave entrance is the last hurdle. The full Alpha boss guide on this site covers Geoclaw itself.
Alpha Minespine and the Minespine cave
Not every hidden cave is blocked by vines. The Alpha Minespine cavern sits past a boulder, and you get beneath it with an Aniimo that has the tunnel ability. Budclaw is one that works. If no Aniimo on your team can tunnel, you will not get through, so sort that out before you make the trip.
The Minespine cave is blocked by dense dark rock. Use Gravity Pull to move explosive barrels onto the rock, then blow it up. The barrels do the damage; Gravity Pull is how you get them into position. Field abilities like these have their own guide on this site if you need the basics.
Where to start
Collect Lumin Amber from puzzles, mini-games, time trials, Sanctums and blessed Aniimo until you have 120, then infuse it into the Breezy Plains branch. Head west to the stream and lake for Geoclaw and be ready for the Lumberer past the hole. Take a tunneller such as Budclaw for Minespine, and use Gravity Pull and the barrels for Minespine.
