You know that feeling when you finally reach the peak of Mt. Gelmir, expecting maybe a nice view or a lore-heavy cutscene, and instead, a massive, obsidian-crusted bull-insect hybrid rockets out of a crater to ruin your Tuesday? That's the Full-Grown Fallingstar Beast. It’s arguably one of the most jarring difficulty spikes in Elden Ring. Honestly, it's a fight that tests your patience more than your actual reflexes. Most players hit this wall and immediately start questioning their build choices.
Is it a bird? Is it a plane? No, it’s a sentient piece of space debris that really, really hates you.
The Full-Grown Fallingstar Beast is the fully evolved form of the lesser Fallingstar Beasts you've probably encountered in tunnels or that random crater in Altus Plateau. But this one? It’s different. It’s faster. It hits like a freight train made of diamonds. If you're struggling, it’s likely because you’re treating it like a standard boss. It isn’t. It’s a physics puzzle with teeth.
Why the Full-Grown Fallingstar Beast is a Literal Wall
Most bosses in FromSoftware games have a rhythm. You dodge, you poke, you dodge. This beast breaks that. It’s aggressive. It has high physical resistances. It’s basically covered in stone armor that makes most "slashing" weapons feel like you’re trying to cut a mountain with a butter knife.

The arena is the first problem. You’re fighting on a circular plateau with very little room to breathe. One wrong roll and you’re falling to your death, which is just classic Miyazaki design, isn't it? The boss uses every inch of that space. Its charge attack is notorious because it tracks better than you’d expect. If you don't time that sideways roll perfectly, you’re getting tossed into the stratosphere.
Then there’s the gravity magic. The Full-Grown Fallingstar Beast isn't just a physical powerhouse; it manipulates the fundamental forces of the universe. When it starts clicking its mandibles and the ground turns purple, you have about two seconds to realize you’re in trouble. It’s not just one wave of gravity; it’s a three-stage execution. First, it pulls you in. Then, it lifts you up. Finally, it slams you down. If you don't have enough Vigor, that's usually where the "You Died" screen pops up.
Mastering the Mechanics and Finding the Weak Spots
You’d think a giant rock monster wouldn't have a weak spot, but it does. Sorta.
Look at its head. Specifically, look at the fuzzy, white, fleshy bit right between the pincers. That’s the "eye" or the soft tissue. If you hit that, you deal actual damage. The problem? It’s located right where the most dangerous attacks come from. It’s a high-risk, high-reward situation.
Breaking the Charge
Did you know you can actually stance-break this thing mid-charge? It’s terrifying to try, but if you hit it with a heavy attack or a well-timed spell (like Rock Sling) right as it's rushing you, the beast will recoil. It’s a total game-changer. Most people just run away. Don't just run. If you’re brave enough to stand your ground and bonk it on the nose, you get a massive window for a critical hit.
Dealing with the Gravity Slam
When it starts the purple AOE, don't just roll randomly. The timing is specific. You want to roll out of the initial circle, then wait for the upward thrust. If you’re caught in the lift, you’re probably going to take the slam. Some players find success by just sprinting as far away as possible the second they see the purple sparks. It’s the safest bet.
The Best Builds for This Fight
If you're using a Katana, I'm sorry. Bleed is great for a lot of things in Elden Ring, but this thing is made of rock. It doesn't bleed easily. You’re basically trying to make a boulder have a nosebleed. It’s possible, but it’s the hard way.
- Strike Damage is King: Hammers, maces, and flails. These ignore a huge chunk of the beast’s natural armor. A Great Stars or even a basic Morning Star with some heavy investment will do way more work than a Moonveil here.
- Magic Users: You actually have it kinda easy. Rock Sling is the MVP. It deals physical "Stance" damage. Since it scales with Sorcery, you can sit back and pelt the Full-Grown Fallingstar Beast from a distance. If you hit the head enough, it’ll go down for a riposte.
- The Poison Strategy: If you’re really stuck, you can play dirty. Poison and Scarlet Rot work. It’s slow. It’s "cheesy" to some. But hey, a win is a win.
The beast is also surprisingly weak to elemental damage like Fire or Lightning compared to its massive Physical resistance. If you’re a Faith build, hitting it with Lightning Spear or some pyromancies can actually bypass that annoying stone hide.
Common Mistakes Most Players Make
Stop staying behind it.
I know, it sounds counter-intuitive. In most games, the "butt" is the safe zone. Not here. The Full-Grown Fallingstar Beast has a tail that acts like a whip. It has incredible range and can hit you even if you think you’re at a safe distance. Plus, it can kick you with its hind legs.
Another mistake? Using Torrent.

Yes, you can use the horse in this fight. Should you? Probably not for the whole thing. While Torrent is great for closing the gap or avoiding the gravity slams, you lose your ability to "I-frame" through attacks. One hit from the beast will usually knock you off Torrent, leaving you flat on your back while the boss prepares a follow-up. It’s better to stay on foot for the precision dodging and only hop on the horse if you need to chase the beast down after it jumps across the arena.
The Lore Behind the Beast
For the lore hunters out there, these things are fascinating. They are basically the larval or adolescent forms of Astel, Naturalborn of the Void. Think about that for a second. This terrifying, mountain-topping monster is just a "teenager" in the grand scheme of cosmic horrors.
They arrive via meteors. That’s why you always find them in craters. They consume the earth and minerals around them to grow. The Full-Grown Fallingstar Beast is the peak of this earthly evolution before they eventually undergo a metamorphosis into those creepy, skeletal dragonfly things that haunt the underground cities.
Understanding that they are "beasts of the void" explains why gravity magic is their primary tool. They aren't just using magic; they are magic. They are physical manifestations of the celestial forces that govern the Lands Between.

Practical Steps to Victory
If you're staring at the fog gate (or the spirit spring jump) right now, here’s exactly what you should do:
- Check your weapon type. If you’re using Slashing or Piercing, consider swapping to something with Strike damage. Even an unupgraded hammer with a high-damage Ash of War can be more effective than your main sword.
- Equip the Greatshield Talisman. This boss does massive physical damage. Anything to boost your negation will save you from being one-shotted.
- Target the head. It sounds scary, but the damage multiplier is too good to ignore. Lock on to the head, not the body.
- Manage your stamina. The fight is a marathon. If you burn all your green bar trying to get three hits in, you won't have enough left to dodge the inevitable tail swipe. One hit, then reset.
- Use Spirit Summons wisely. If you use the Mimic Tear, make sure you're equipped with a heavy weapon when you summon it. If you use Tiche, she’s great for the percentage-based damage, but she might struggle to stay alive against the AOE attacks.
The Full-Grown Fallingstar Beast is a gatekeeper. It’s meant to stop you from reaching the Volcano Manor easily. But once you realize it's more about timing and positioning than raw DPS, the fight becomes much more manageable. Don't let the rock-bull win. Just stay patient, hit the soft spots, and watch out for the purple glow.
Go get your Smithing Stones and move on to Rykard. You've got a god to devour.
