How to summon Ra-Akar in Core Keeper
Alright, so you wanna fight Ra-Akar, the biggest, meanest beetle in Core Keeper? Great plan, except he’s not just chilling on the surface waiting for a duel. Nope, this guy is buried deep in the sands, sleeping like some ancient menace that really doesn’t wanna be disturbed. But we’re disturbing him anyway. So, if you’re ready to knock on the door of doom, let’s talk about how to summon Ra-Akar and bring the pain.

How to find Ra-Akar’s lair
First things first, before you can wake up Ra-Akar, you need to find him. This guy isn’t walking around like some regular mob - he’s got a whole hidden arena somewhere in the Desert of Beginnings, and it’s your job to locate it. There are two ways to go about this.

Option one: the caveman method, aka running around aimlessly hoping you bump into his lair. This could take hours, days, maybe even your entire Core Keeper career. Not ideal.
Option two: the smart way, which is crafting the Ra-Akar the Sand Titan Scanner. This beauty will mark his exact location on your map so you can stop digging holes like a clueless mole. You can craft the scanner at the Ancient Hologram Pod, but it’s gonna cost you:
- 20 Ancient Gemstones
- 20 Mechanical Parts
- 20 Scarab Wingcovers

Ancient Gemstones and Mechanical Parts? Easy. But Scarab Wingcovers? Oh boy. You won’t get these from fighting enemies or looting chests. No, they’re just lying around in the desert, waiting for you to walk over them and pick them up. Sounds simple? Try collecting 40 of them without losing your mind. If you’d rather avoid this grind, you can search manually for Ra-Akar’s arena - look for a square-shaped structure buried in the sand about 600 blocks away from the map’s center. Found it? Good. Now it’s time to wake up the beast.

How to summon Ra-Akar
Okay, you’ve found the lair. Now you just need to knock - except instead of knocking, you’re going to detonate the entire floor. Meet the Thumper, a high-powered shockwave generator designed specifically to wake up angry sand monsters. You can’t just buy one at the shop, though - you have to craft it at the Ancient Hologram Pod, and it’s gonna cost you some serious resources:
- 50 Fiber
- 50 Planks
- 30 Scarlet Bars
- 30 Galaxite Bars
- 10 Mechanical Parts
- 20 Ancient Gemstones

Once you’ve built your Thumper, take it to the exact center of Ra-Akar’s lair. Place it down, activate it, and step back, because what happens next is pure chaos.
The ground rumbles. The sand shakes. And then, BOOM - Ra-Akar explodes out of the ground like a horror movie jump scare, screeching and ready to ruin your day. The fight begins immediately, so make sure you’re not standing there in your underwear when this guy wakes up.

How to prepare for the fight
Once Ra-Akar is awake, things get real fast. If you think you can just stand there and trade blows, think again. This Titan has a nasty arsenal of attacks designed specifically to make you regret your life choices. Here’s what to do before summoning him, unless you wanna end up in the dirt in under ten seconds.
1. Stack movement speed. Ra-Akar is fast, and his homing triangle attack will chase you down unless you can outrun it. Equip anything that boosts movement speed - your legs will thank you later.
2. Bring ranged weapons. Getting up close and personal? Bad idea. Ra-Akar spits energy orbs, summons exploding scarabs, and generally does everything in his power to make melee builds suffer. Use ranged attacks to keep your distance and stay alive.
3. Stock up on health potions. You’re going to get hit, no matter how good you are at dodging. Having a full stack of potions might be the difference between victory and an embarrassing trip back to the respawn point.
4. Set up a portal nearby. If you die (and let’s be honest, you probably will), having a portal close to the fight means you can jump back in before Ra-Akar resets. No one wants to farm another Thumper just because they didn’t place a portal.
If you follow these steps, you might just survive this nightmare of a boss fight. And if not? Well, at least you went down in style.

What happens after summoning Ra-Akar
Congratulations! You woke up an ancient bug monster, and now it’s trying to kill you. Ra-Akar isn’t just a tank with high HP, he’s a full-on raid boss with a 160,000 health bar and enough attack patterns to make you question your gaming skills.

If you can survive the chaos, dodge like a professional parkour artist, and land enough hits before your potions run out, you’ll eventually take him down.

And when he finally crashes to the ground, guess what? You’re rewarded with the Giant Bug Brain - one of the most important crafting materials in the game. You’ll need it to craft the Hydra Altar, which lets you summon the game’s final bosses.

Of course, if you wanna fight Ra-Akar again, you’ll need to craft another Thumper. So if you’re planning on farming him, stock up on resources - you’re gonna need them.
Summoning Ra-Akar isn’t just about waking up a big bug—it’s about preparing for one of the toughest fights in Core Keeper. First, you gotta find him, then gather the materials, and finally, drop that Thumper and brace yourself for absolute madness. This boss fight is chaotic, fast, and punishing, but also one of the most rewarding. So get your gear, get your potions, and get ready to take on the Sand Titan.
