How to get Giant Bug Brain in Core Keeper Update
Alright, buckle up. This isn’t just any boss fight, this is Ra-Akar, the biggest, baddest, buggiest beast crawling around the Desert of Beginnings. He’s got legs the size of tree trunks, a health bar that makes you question your life choices, and attacks designed specifically to ruin your day. But you? You’re built different. You’re gonna take this bug apart and walk away with that precious Giant Bug Brain. But first, we gotta find him.

How to find Ra-Akar the Sand Titan
So, you wanna fight Ra-Akar? Great, but where is he? The Desert of Beginnings is huge. Like, walk-for-an-hour-and-still-see-sand huge. And Ra-Akar? He doesn’t just chill on the surface, waiting for a challenge. No, he’s deep underground, lurking like some kind of ancient horror waiting to be disturbed. There are two ways to find him. First, the manual way, which means running around like a headless chicken until you stumble upon his lair. Sounds fun, right? Yeah, no.

The second way, the big brain way, is using the Ra-Akar the Sand Titan Scanner. This magic little gadget pinpoints his exact location so you don’t waste your time digging in random directions. Craft it at the Ancient Hologram Pod using 20 Ancient Gemstones, 10 Mechanical Parts, and 40 Scarab Wingcovers. Scarab Wingcovers are a pain to collect because they don’t drop from mobs; you just have to find them lying around like someone forgot to clean up after a giant bug party. Once you’ve got the scanner, fire it up, and bam, there’s your target. Now all that’s left is waking the big guy up.

How to summon Ra-Akar
Finding Ra-Akar was the easy part. Now we need to wake him up, and for that, you need a Thumper. No, not the cute bunny from that old cartoon, this Thumper is a shockwave machine of doom that lets Ra-Akar know it’s time to throw down. You’ll craft it at the Ancient Hologram Pod, and it’s gonna cost you: 50 Fiber, 50 Planks, 30 Scarlet Bars, 30 Galaxite Bars, 10 Mechanical Parts, and 20 Ancient Gemstones. Yeah, it’s expensive, but no one said fighting titanic death beetles was cheap.

Once you have the Thumper, head to the exact spot the scanner marked, drop it down, and boom, the ground shakes, the sand trembles, and suddenly, the biggest bug you’ve ever seen erupts from below. The fight is on.
How to defeat Ra-Akar the Sand Titan
Alright, deep breath. This is not an easy fight. Ra-Akar is fast, angry, and absolutely not in the mood to die today. He’s got 160,000 health, which means you’re gonna be here a while. Let’s talk about how to survive this mess.

First off, his main attack. Ra-Akar spits out energy orbs that bounce around the arena like they’ve got a mind of their own. Dodge or die, simple as that. Then come the Bomb Scarabs. These little maniacs rush you down and explode, dealing massive damage. If you see one coming, drop whatever you’re doing and take it out.
And then, the worst part. Ra-Akar summons homing triangle projectiles. These bad boys do not miss unless you’ve got insane movement speed. If you thought running in circles was just for warmups, guess what, it’s now your full-time job. Equip anything that boosts your movement speed or prepare to get flattened.

Best strategy? Ranged combat. If you try to go melee, you’re gonna have a bad time. Keep your distance, dodge constantly, and don’t be greedy with your attacks. Bring health potions, reinforced armor, and if possible, a friend. Seriously, this fight is way easier with backup.
How to claim the Giant Bug Brain
You did it. You actually did it. Ra-Akar is down, and now it’s time for your well-earned prize. The Giant Bug Brain is a guaranteed drop, along with the Soul of Ra-Akar, which is another cool thing you can flex on your friends with. This big brain is a must-have for progressing further in Core Keeper. You’ll need it to craft the Hydra Altar, which lets you summon the final bosses. No Bug Brain, no endgame, simple as that.

Thinking about farming Ra-Akar? Bad news. You need a new Thumper every time you wanna fight him again. So if you want extra Giant Bug Brains, get ready to gather more resources and repeat the process. It’s a grind, but hey, that’s life in Core Keeper.
Fighting Ra-Akar is one of the toughest challenges in Core Keeper, but let’s be real, it’s also one of the most epic. The sheer size of this boss, the chaos of the fight, the insane speed you need to survive—it’s all pure adrenaline. But now you know exactly what to do. Find him. Summon him. Dodge like your life depends on it (because it does). And claim that Giant Bug Brain. Good luck, and may your movement speed be high and your dodges be flawless.
