Luma Island: Complete Mining Guide

Whether it's a survival game like Minecraft or a cozy, life-sim one like Fields of Mistria, mining is often a pretty important mechanic, and Luma Island puts its own spin on it. You'll be delving deep into old caves located around the island in search of useful metals and valuable gems, and you may even find some treasure too.

Besides the resources, spiders make their home in the caves, and they're all too eager to take a bite out of any unprepared explorers looking for resources. A rock might drop onto your head, and even the darkness itself seems out to get you.

How To Locate The Caves

While you can find small amounts of ore nodes in specific mountainous locations or after unlocking certain temple rooms, the main place you'll get ore, and the only place you can mine for gems, is in the biome-specific caves.

• The first available cave is the Abandoned Farm Cave, and it's located next to your house.
• The second available cave is the Lost Forest Cave, and you need to repair the town's bridge so you can access the Forest. It's located in the northern corner of the western side of the area, past the stone bridge.
• The third available cave is the Frozen Mountain Cave, and you need to repair the town's Cable Car to ride it to the Mountain. It's located northwest of the entrance to the area.

Some areas, such as the Forest, also have minor caves that contain Charcoal and different Ores, but these don't have gems or enemies, are much smaller, and can't be reset once you've mined all the resources found in them.

Many of the minor caves can help you access new areas or give you a shortcut closer to the entrance of an area, so they're still worth exploring.

You'll also begin finding unfinished campsites outside a major cave once you reach the Forest. They'll have all the basic crafting stations, like a Sawmill, Kiln, Ore Smelter, and Simple Workbench, and you can finish their construction with the regional material equivalent.

How To Explore The Caves

When you first go down into a cave, you'll start in a well-lit area with a few trees and bushes, while the rest of the area is in complete darkness except for glowing gems in the distance if they've spawned close enough.

You'll need to use one of three torch types to light the area around you as you explore to keep the darkness from consuming you and sending you back to the entrance. Each area has its own Resin and Torch type that differs in light color and effectiveness:

Torch Type	Resin Needed	Light Radius	How Long It Lasts
Farm Torch	Farm Resin	Small	Two In-game Days
Forest Torch	Forest Resin	Medium	Four In-game Days
Mountain Torch	Mountain Resin	Large	Six In-game Days

Torches will go out after a certain amount of in-game time passes, but you can reignite them by running over them.

Charcoal and the area's ore type can be found throughout the cave, but the gems are always located farther out according to their rarity, with the lowest rarity located closer to the cave entrance, and the rarest one near the edge of the cave's interior.

Each cave, save for the Abandoned Farm Cave, also introduces a rare, dangerous variant of its regional stone that can kill you and send you back to the entrance if you don't avoid it.

• For the Lost Forest Cave, rocks may explode into a cloud of poison gas that will cause your screen to go hazy. These rocks are always large and pointed.
• For the Frozen Mountain Cave, rocks may detonate and explode after a few seconds, destroying rocks and ores around them in a small radius. These rocks are always flat, round, and medium-sized.

While exploring, you'll also find Old Barrels and Crates you can break with your Whip, and these mostly contain cave-related items, such as Torches and Flares, and occasionally a small amount of Ore and Charcoal.

Flares are great for revealing a wide radius around you briefly and can save you from dying if you run out of torches.

Rocks will also occasionally fall from the ceiling and create a new boulder that can block a path you've made, but they often fall on top of other boulders instead, and it's rare for them to hit you since they spawn on the outskirts of where you're standing.

How To Deal With Spiders

The longer you stay inside a cave, the more likely it is that a Spider enemy will spawn near your location, and these serve as your main threat while in a cave.

A Spider will start wandering around the cave once they've spawned, and if you or they get close to them, they'll initiate a chase and begin hunting you down unless you run far away enough to lose its attention.

You can tell if a Spider is spawning as they always produce a flash of colored light at their location while spawning, and they make a loud hissing noise.

Besides those that spawn over time, mining a gem of any type also produces a loud noise that attracts Spiders and each hit drastically increases the chance of a Spider spawning near you.

If a Spider comes after you, or you don't want to be bothered by it, use your Whip to fight them off. Each hit with your Whip will stun them for a few moments, and you can time it so you stun them each time they try to move until they're dead, or it can just give you a chance to escape or avoid them.

You can farm Spiders for their rare drops like Webbed Gems to sell by mining gems and making them spawn near you.

Each type of cave has a Spider variant, with a different appearance and spawning light color, but they all do the same amount of damage, and the main difference between them is how fast they go.

• The Farm Spider is the slowest.
• The Forest Spider is the second fastest.
• The Mountain Spider is the fastest.

In mid-to-late game caves such as the Frozen Mountain Cave, multiple Spiders can spawn at once, either naturally or by attracting them via striking a gem.

How To Reset A Cave's Interior

Eventually, a cave can run out of resources, and if this happens, you'll need to locate the Cave Reset Beacon and use it to spawn new resources.

Each cave has one, and they're always located somewhere along the very edge of the cave's interior, so they require quite a bit of exploring and torches to reach them. They sit in a well-lit area like the cave's entrance, so you can see them from afar if you've gone deep enough.

When you find the beacon, all you have to do is interact with it and a countdown will start. You'll have 90 seconds to mine any last resources and exit the cave, or else it will collapse on you and send you back to the entrance.

Next time you go back inside, the entire layout will be reset, allowing you to get more resources. There isn't a limit to how many times you can reset a cave, but you will have to find the beacon again each time.

All Mining Resources And Their Uses

All cave resources are important for upgrading your tools, but ore and gems provide the main materials needed for the Blacksmithing and Jewelrycrafter Professions, and you'll need metal bars for making the magnets as a Treasure Hunter.
