Hexapod Boss Guide – Mortal Shell 2

TL;DR

• The Hexapod is the boss of the Withered Shoals gate in the Ruins of Mammon.
• Reach it via the Nameless Pass Beacon, then follow the path to the boss area and jump to the void.
• Summon Proxima before the fight — she pulls aggro and gives you free windows to attack and apply status effects.
• All its melee attacks are telegraphed — it spreads its tentacles wide before striking, giving you time to dodge.
• When it jumps back and a red icon flashes, dodge sideways — that’s the Squid Surge charge incoming.
• In the second phase it burrows underground. Watch for the red indicator and dodge to the side when it erupts.
• Beating it rewards the Hexapod Core Tarstone for the Axatana.

The Hexapod boss in Mortal Shell 2 is one of the more visually striking encounters in the game. It’s a strange, fast-moving tentacle creature found in the Withered Shoals — described by Ruk as something that doesn’t belong to this world, said to have fallen from the sky. Despite how intimidating it looks, most players agree it’s actually one of the more manageable major bosses once you understand how its attacks work.

The key to this fight is reading the telegraphs. Almost every attack the Hexapod does has a clear visual warning before it lands. If you’re still working through the Mammon gates, our guide on how to beat Droeg the Conqueror covers the first Mammon gate boss. For the full campaign roadmap, see our Mortal Shell 2 all boss list.

Here’s everything you need — where to find the Hexapod, every attack explained, and the cleanest strategy to take it down.

Where to Find the Hexapod in Mortal Shell 2

The Hexapod is the final boss of the Withered Shoals — the southwest Corrupted Gate in the Ruins of Mammon. This is one of the three Mammon gates you need to clear to collect enough Ova for the campaign’s final area.

Here’s how to get there:

• Enter the Withered Shoals through the Gate of Mammon.
• There are three beacons in this area: the Ossinite Falls Beacon, the Nameless Pass Beacon, and the Hexapod’s Burrow Beacon. Activate them as you push through.
• From the Nameless Pass Beacon, follow the nearby path through the area.
• When you reach the area with Ruk, jump down to the zone below him first. Head back through the bone tunnel to find the Depleted Gland — a useful item worth picking up before the fight.
• Then jump to the void. A short cutscene plays introducing you to the Hexapod. The fight begins immediately after.

Tip: Spend a Glimpse to permanently summon Proxima as your spirit ally before jumping to the void. Proxima is tied to the Hexapod’s storyline and is particularly effective in this fight — she pulls the boss’s attention and can use her Triarch Repeater sidearm to deal ranged damage while you attack. This is one of the best summon matchups in the game.

Note on finding the beacon after the fight: The post-fight area can be disorienting due to mist. If you can’t find the beacon after defeating the Hexapod, exit the game — you’ll respawn at the beacon above the arena. Drop back down, and without moving, turn the camera to face the back of the arena and walk forward to find it.

The Hexapod – Overview and Lore

The Hexapod is described as an otherworldly creature — something that, according to Ruk, fell from the sky just as the Undermether did. Its origin is completely unknown. It’s a beast capable of devouring anything in its path, and the Withered Shoals has essentially become its territory. The fight also ties into Proxima the Broodseeker’s storyline, which is why she’s the designated spirit summon for this encounter.

In terms of appearance, it’s a large, fast-moving creature with multiple tentacles it uses both as weapons and as tools to burrow underground. It’s mobile, constantly repositioning, and it will always try to face you — which actually works in your favour once you know how to read its attacks.

Hexapod – All Attacks Explained

The Hexapod’s attack set has a clear phase structure. Phase 1 is purely tentacle-based melee. Phase 2 introduces the underground burrowing attack. Every attack has a readable tell — this is genuinely one of the most telegraphed boss fights in the game.

Phase 1 Attacks

Lateral Tentacle Slash

The Hexapod sweeps its tentacles horizontally across its body — either left to right or right to left. This is its most common opener and happens frequently throughout phase 1. The motion is slow and wide. You can dodge backward to avoid it cleanly, or — if you’re comfortable — dodge into the attack using iframes and end up right next to the boss in a punish position. Either works. Just confirm which direction the sweep is going before committing to your dodge direction.

Triple Tentacle Stab

The Hexapod lines up three tentacles and drives them forward in a consecutive stabbing motion directly in front of it. This is a straight-line attack with decent reach. The best response here is dodging sideways — stepping to the side of the stab line puts you completely out of the hitbox and right next to its body for a follow-up hit.

Overhead Slash

The Hexapod raises its outer tentacles and brings them down in an overhead arc. This is the easiest attack to parry in the entire fight — the motion is slow and the windup is very clear. If you want to practice parrying, this is the attack to do it on. Otherwise, dodging backward works just as well. After this attack lands (or misses), there’s a short recovery window before the Hexapod resets its position. Use it for a quick two-hit combo.

Tentacle Flurry (Running Slash)

The Hexapod unleashes a rapid flurry of slashes using all its tentacles while moving either toward or away from you. This is the chaotic version of the lateral sweep — faster, more hits, and harder to track. The best answer is to create distance when you see this starting. Run away and let the flurry end before re-engaging. Don’t try to dodge through individual hits here — just get out of range entirely.

Squid Surge (Charge Attack)

The Hexapod jumps backward, putting distance between you. Then a red indicator flashes on its body. That’s your signal — it’s about to charge straight at you at speed. Dodge sideways when it launches. Let it rush past you. The failed charge leaves it in a recovery animation for a second or two. These are your safest and most reliable punish windows in the entire fight. Every time you successfully dodge the Squid Surge, go in for several hits — it’s the best consistent source of damage in phase 1.

Don’t dodge backward for this. Backward dodges keep you in its path. Sideways puts you out of the lane entirely.

Phase 2 Attacks

Unblockable Unparryable Slash (Phase 2 Opener)

When the Hexapod’s health drops and phase 2 triggers, it signals the transition with a specific slash — an unparryable version of the overhead slash. This move is used to create distance from you before it starts its underground sequence. When you see the red warning icon flash alongside a slash motion that can’t be parried, back off and give it room. The burrowing sequence is about to begin.

Underground Burrow and Eruption – Phase 2’s Main Threat

This is the attack that catches players off guard in phase 2. After the unparryable slash creates distance, the Hexapod charges up briefly from a distance then digs into the ground and tunnels toward you underground. You’ll see a red indicator appear at your feet or tracking toward you across the arena floor. When you see it — dodge to the side immediately.

The Hexapod erupts out of the ground at the indicator’s location. If you’re standing there when it surfaces, the hit is devastating. If you dodge sideways in time, the eruption misses and the Hexapod is briefly exposed above ground. That’s your punish window — get a few hits in before it repositions.

The arena is large, which helps here. You have room to read the indicator’s movement and dodge early rather than last-second. Use the open space to your advantage and avoid cornering yourself against the arena edges.

Best Strategy to Beat the Hexapod in Mortal Shell 2

This is one of the more forgiving major boss fights in Mortal Shell 2 once you know what to look for. The attacks are slow and clearly animated. The fight rewards patience and reading the tells rather than aggressive pressure.

Summon Proxima and Apply a Status Effect First

Before jumping to the void, spend a Glimpse to summon Proxima. When the fight starts, run away from the Hexapod and let Proxima pull its attention. Use that time to coat your weapon with a status-effect Tarstone — Stasis, Burn, or Lightning all work well. Stasis is particularly effective because slowing the Hexapod down makes its already-readable attacks even easier to dodge. Getting your status effect applied in the first few seconds of the fight is a big head start. Our best tarstones for beginners in Mortal Shell 2 guide can help you decide what to bring in.

Attack From the Front, Not the Sides

This is counterintuitive compared to most soulslike bosses, but it’s the right call here. The Hexapod constantly rotates to face you, so trying to get behind it or attack from the sides is mostly wasted effort — it’ll turn before you get there. Instead, stay in front of it and attack during its recovery windows. Wait for an attack to end, step in, land two or three hits, then step back before the next move starts. The front is where the punish windows open up.

Watch the Fingers and Tentacles Before Every Attack

Every melee attack the Hexapod does is preceded by it spreading or positioning its tentacles. It physically can’t hide its intent. When it spreads its outer tentacles wide and exposes its head, a strike is incoming — that’s your cue to prepare your dodge. The overhead slash is the clearest example of this. Watching its limbs gives you a half-second lead time on every attack it does.

The Squid Surge Is Your Best Damage Window

Every time the Hexapod jumps back and the red icon flashes, treat it as a gift. Dodge sideways, let the charge go past, then immediately step in for a combo during the recovery. These moments are safer than trying to attack after individual tentacle swings. If you’re playing a shell that rewards aggressive dodging, this fight will feel very natural. Tiel’s perfect dodge Shadow Strike pairs beautifully with these Squid Surge punishes. Our best shells for beginners in Mortal Shell 2 guide covers what each shell offers if you’re still deciding on your setup.

Fill the Stagger Bar to Create Bigger Windows

Landing consistent hits builds up the Hexapod’s stagger bar. When it staggers and breaks, you get a larger punish window than usual — use your weapon’s special ability or your hardest-hitting combo here. One thing to watch though: when the Hexapod staggers and is about to recover, reposition to its flank if possible. When it comes out of a stagger, it can immediately use an unblockable grab directly in front of itself. Being to the side when it recovers sidesteps that entirely.

Phase 2: Trust the Red Indicator

When the Hexapod burrows underground, don’t panic. Don’t run randomly. Watch the red indicator tracking across the ground and dodge sideways out of its path at the right moment. The arena is big enough that you have time to read and react. After the eruption, go in for your hits. This attack is predictable once you’ve seen it once or twice — it just needs a calm first reaction rather than a frantic scramble.

Use Ranged Attacks and Your Sidearm

When the Hexapod is retreating or recovering at range between attacks, your sidearm can chip in some extra damage from a safe distance. Some players also recommend the Forgotten Crossbow specifically for this fight, as it can provide knockback to interrupt certain approach animations. Our best sidearms for beginners in Mortal Shell 2 guide is worth checking if you want to bring the right ranged option.

Hexapod – Rewards

Defeating the Hexapod gives you:

• Hexapod Core – An Ability Tarstone that works exclusively with the Axatana. It costs 60 Resolve to activate and lets you carve through enemies with a rapid succession of strikes. It turns the Axatana into an excellent burst damage option and works especially well during stagger windows. You can upgrade this Tarstone further by giving Franz the Etching Needle — find it in a bone chest near the Magdalena boss area before her fight.
• Gloom – A large sum of upgrade currency (54,250 Gloom).
• Ovum – Earned after cleansing the beacon that appears post-fight, bringing you closer to unlocking the game’s final area.

If you want to get more from the Hexapod Core and your other Tarstone drops, our Mortal Shell 2 Tarforge guide covers how to upgrade and expand your Tarstone options back at Marrow Keep.

What Comes After the Hexapod?

With the Hexapod down, two of the three Mammon gates are cleared (assuming you already beat Droeg). The final Mammon gate is the Faded Citadel, where Sir Isaac, the Scholar-Prince waits. Isaac is widely considered one of the harder gate bosses — a fast, aggressive melee fighter who gets even more dangerous when his shield is destroyed at half health. Make sure you’re upgraded before heading in.

Between gates, always make time for a full Marrow Keep stop — sell trade items, top up Gloom spending, and check weapon upgrades. Our guide on permanent items in Mortal Shell 2 is also worth checking so you don’t miss anything collectible while working through Mammon. And if you need to track down any weapons before the next fight, our Mortal Shell 2 all weapon and sidearm locations guide has everything mapped out.

Quick Tips Summary

• Summon Proxima before jumping to the void — she’s the ideal ally for this fight.
• Apply a status effect while Proxima holds aggro at the start. Stasis works great.
• Attack from the front — the Hexapod always faces you, so sides and back aren’t accessible.
• Watch the tentacles spread before every melee attack — that’s your dodge cue.
• Dodge sideways on the Squid Surge — then punish the recovery. Best damage window in the fight.
• Reposition to the flank after a stagger break — the recovery can trigger an unblockable front grab.
• Trust the red indicator in phase 2 — dodge sideways out of the burrow path, then punish the eruption.
