If you’ve ever spent hours fighting through the Underworld trying to boost your melee damage for upcoming hardmode bosses, you’ve probably wondered how to get magma stone terraria. This underrated pre-hardmode accessory is a game-changer for melee builds, adding a consistent fire damage debuff to every hit that sticks around even after you unlock hardmode gear. I’ve farmed this item dozens of times across playthroughs, and I once spent three hours grinding for it on a master mode run before I realized I was using a weapon that knocked every bat straight into lava, so I know how frustrating the grind can be if you don’t know what you’re doing.
How to Get Magma Stone in Terraria: Core Farming Requirements
Before you head down to the Underworld to start your farm, you should know exactly which enemies drop the item and what gear you’ll need to make the process as painless as possible. Only Hellbats and Lava Bats drop the Magma Stone, so you don’t need to waste time fighting other Underworld enemies like Demons or Bone Serpents to get it. The base drop rate is only 2% per kill, so don’t get discouraged if you don’t get it in the first 20 kills.
You don’t need any hard-to-find items to start farming, but these supplies will cut your grind time significantly:
If you’re playing on Journey mode, you can skip most of these preparations entirely by setting your spawn rate to maximum and turning on invulnerability if you don’t feel like dealing with lava damage.
Fastest Farming Strategies for Magma Stone
The method you use to farm the Magma Stone will depend on how far you’ve progressed in your playthrough. For brand new players who haven’t beaten any bosses yet, the simplest method is to dig a hellevator straight down to the Underworld, build a 20-block long platform 10 blocks above the lava layer, and stand in the middle to kill any bats that spawn. I prefer using the Space Gun for early farming because it has low knockback and hits multiple bats at once, even if you don’t have a lot of mana to spare.
If you’ve already beaten Skeletron and have access to the Dungeon, you can speed up the process even more. Using a Water Candle will double enemy spawn rates, cutting your average farm time by almost half. You can also place a Battle Potion to increase spawn rates further, though you’ll have to deal with more unwanted Underworld enemies spawning alongside the bats.
So if you’re playing with friends, bring one or two people along to help clear out extra enemies and kill bats faster. More players means more spawns, which means more chances to get the Magma Stone to drop for everyone in the group.
Common Mistakes to Avoid When Farming Magma Stone
Even if you have all the right gear, small mistakes can turn a 20-minute farm into a three-hour slog. The most common mistake new players make is building their farming platform right above a large, open lava lake. Bats will regularly fly down into the lava to escape, and they’ll either despawn before you can kill them or take so much lava damage that they die before you land a hit, so you won’t get credit for the kill. You can block off open lava pockets with ash blocks to prevent bats from escaping into the lava, and you won’t have to worry about losing half your spawns to the environment.
Another big mistake is using weapons with high knockback, like the Muramasa or a strong bow. You’ll end up flinging bats straight into the lava before you can land enough hits to kill them, which wastes your time and cuts down on your number of possible drops. Stick to low-knockback, wide-range weapons to avoid this issue entirely.
Don’t forget to keep an eye on the ground once you start killing bats, too. The Magma Stone is a small, bright red item that blends in almost perfectly with the Underworld’s red ash background. It’s easy to miss if you’re not paying attention, so pop a Heartreach potion to pull all drops straight to you without having to run around the platform to pick them up.
Best Uses for Your Magma Stone Once You Get It
On its own, the Magma Stone adds 4 extra fire damage to every melee hit, and applies a 3-second On Fire! debuff to enemies that deals 4 damage per second. That might not sound like a lot in the early game, but it adds up extremely fast when you’re using fast melee weapons like the Blade of Grass or Night’s Edge. It works with all melee weapon types, including yoyos, flails, and boomerangs, so it’s a useful accessory even if you don’t use a traditional sword build.
You can combine the Magma Stone with an Obsidian Rose later to make the Molten Skull Rose, one of the best pre-hardmode accessories for melee builds. This upgraded accessory keeps the Magma Stone’s fire damage and debuff, and also adds 7 defense, reduces lava damage by 30 / 50 (depending on your game mode), and makes you immune to the Burning debuff from hellstone blocks. It’s strong enough to carry you all the way through the Wall of Flesh fight and into early hardmode.
Even if you don’t main a melee build, it’s worth keeping a Magma Stone in your inventory for boss fights against enemies that aren’t immune to fire. It works great for adding extra damage during the Eye of Cthulhu, Skeletron, and Queen Bee fights, and it will make your first few hardmode boss runs a little easier until you can get higher-tier damage accessories.
At the end of the day, learning how to get magma stone terraria is well worth the small time investment, even if you’re not planning to main a melee build for your playthrough. The fire damage boost and debuff will make your pre-hardmode boss fights much smoother, and it gives you a head start on crafting some of the best early hardmode melee accessories. Don’t get discouraged if you have bad RNG on your first farm run; bring a friend to help kill bats faster, pop a luck potion, and you’ll have one in your inventory before you know it.
