You've probably seen the trailer by now. The one where a group of "Engineers" treks across a desolate, hauntingly beautiful landscape to stop a Paintress from literal deicide. Clair Obscur: Expedition 33 has basically taken the internet by storm, not just because it looks like a high-budget fever dream of Final Fantasy meeting 17th-century France, but because of its world-building. At the center of this weird, turn-based revolution is something called the Medalum.
It sounds like a mouthful. It is. But if you want to understand why Sandfall Interactive is betting the house on this specific mechanic, you have to look at how it bridges the gap between old-school RPG gear and modern, reactive gameplay. Honestly, most games just give you a "Ring of +5 Strength" and call it a day. Expedition 33 isn't doing that.
The Medalum is less of a passive stat-stick and more of a core identity for your character. In the world of the game, the Paintress wakes up every year to paint a number on a monolith. Everyone that age turns to smoke. Our protagonists are part of Expedition 33—the group trying to end this cycle before the number hits zero. To survive, they use these intricate artifacts. They're essentially magical hubs that dictate how you interact with the game’s unique "reactive" turn-based combat.

Understanding the Medalum Mechanic
Let's get into the weeds. Most people think a Medalum is just a fancy word for a skill tree. That’s wrong. While it does house your progression, it functions more like a customizable engine. You aren't just picking "Fireball" or "Heal." You are slotting specific shards and fragments into the Medalum to fundamentally change how your character's turn plays out.
The game uses a system where timing actually matters. Just because it’s turn-based doesn't mean you can go make a sandwich while the enemy attacks. You have to parry. You have to dodge. The Medalum dictates the efficacy of these maneuvers. For example, Gustave (the lead with the massive blade) can be kitted out via his Medalum to focus entirely on counter-attacks. If you slot it right, a successful parry doesn't just negate damage—it triggers a massive follow-up that can break an enemy's stance.
It’s about synergy.
You might find a fragment in the ruins of the Belle Époque-inspired world that adds a bleed effect to any "Perfect" timed hit. You shove that into your Medalum. Suddenly, your defensive playstyle is your primary source of DPS. It's a clever way to keep players engaged during the enemy's turn, which is usually the most boring part of any RPG.
The Customization Depth Nobody Talks About
Sandfall has been somewhat secretive about the exact number of combinations, but from what we've seen in the technical deep dives, the flexibility is pretty wild. You have different "layers" within the Medalum.
Think of it like this: The base Medalum is the frame. The shards are the gears. The essence is the fuel.
One thing that’s super interesting is how the Medalum interacts with the "Lumiere"—the light-based resource in the game. You can essentially build a glass cannon character who gains massive power but loses a chunk of their Medalum’s defensive capabilities. It’s a high-stakes gamble. If you miss a parry, you're dead. If you hit it, you're a god.
There's also a visual component. The developers have a clear obsession with art history—specifically the clair obscur (chiaroscuro) style of high-contrast light and shadow. The Medalum designs themselves look like something out of a master watchmaker’s workshop in 1800s Paris. They are intricate, brassy, and feel "heavy" within the UI. It’s rare to see a menu system feel so integrated into the actual lore of the world.
Why This Matters for the RPG Genre
Let's be real. Turn-based games have been in a weird spot. You have the Persona crowd and the Baldur’s Gate 3 crowd. Expedition 33 is trying to find a middle ground by making the Clair Obscur Expedition 33 Medalum the focal point of player skill.
Usually, in an RPG, if you’re underleveled, you just lose. Here, a well-configured Medalum allows for "skill-expression." If you have the reflexes of a cat and have tuned your Medalum for parry-windows, you can theoretically beat bosses that should be way out of your league. It shifts the focus from "grinding for levels" to "mastering your build."
The Paintress and the Stakes
The reason you’re tweaking this Medalum so obsessively is because of the ticking clock. The Paintress is essentially an eldritch horror with a paintbrush. Every year, she paints a number. This year, it’s 33. The members of the expedition are all 33 years old or younger. They are literally the last line of defense.
The Medalum represents their defiance. It is human-made technology used to fight back against a divine, artistic curse. This narrative weight makes the act of upgrading your gear feel less like a chore and more like a desperate preparation for an inevitable execution.
Real Strategies for Medalum Management
When the game drops, you’re going to be tempted to just auto-fill your slots. Don't.
Based on the gameplay footage from the recent Sony State of Play and the extended developer walkthroughs, here is how you should actually approach your build:
- Prioritize Synergy over Raw Stats: A fragment that gives +10 Attack is almost always worse than a fragment that grants an extra action point on a "Perfect Dodge." Expedition 33 is all about momentum.
- Balance Your Team's Medalums: Maelle is fast. Her Medalum should probably focus on "Chain" fragments. Gustave is the tank; his should focus on "Impact" and "Stagger." If you try to make everyone a jack-of-all-trades, the mid-game bosses will absolutely wreck you.
- Experiment with 'Risk' Fragments: Some shards give you huge buffs but disable your ability to dodge. These are terrifying to use, but against certain slow-moving bosses, they are the key to a quick victory.
The world is also full of "Hidden Echoes"—basically secret areas where you can find unique Medalum components. If you see a weirdly lit corner of a ruined theater, go there. The devs love environmental storytelling, and the best loot is usually tucked away behind a puzzle that requires you to use your character's world-abilities, like the grappling hook.
The Verdict on the System
Is the Clair Obscur Expedition 33 Medalum just a gimmick? Probably not. It feels like a natural evolution of the "Materia" or "Sphere Grid" systems we grew up with, but updated for an era where players want to be more hands-on.
The beauty of it is that it doesn't take away from the strategy. You still have to manage your MP (or the equivalent) and pick the right elemental weaknesses. But the Medalum adds a layer of "feel" to the combat that is usually missing from the genre. When you land that perfect parry because you spent twenty minutes fine-tuning your Medalum's timing windows, it feels earned.
It’s basically a love letter to the era of PlayStation 2 RPGs but with the graphical fidelity of a high-end Unreal Engine 5 tech demo. The contrast is what makes it work. The dark, depressing story of the Paintress versus the shiny, mechanical precision of the Expedition's gear.
Actionable Steps for Future Expeditions
If you're planning on jumping into the game at launch, you need a plan. Don't just wander in blind.
- Master the "Reactive" Timing Early: Go to the first training area and practice the parry windows until they are muscle memory. Your Medalum's power is capped by your own reaction speed.
- Scout for Shards: Don't rush the main story. The world of Expedition 33 is dying, but it's full of powerful artifacts. Every side quest that offers a "Medalum Fragment" as a reward is mandatory if you want to survive the late-game "Erasure" events.
- Watch the Light: Pay attention to the Chiaroscuro effects in combat. The lighting often signals when an enemy is about to unleash a "Heavy" attack that requires a specific Medalum defense to survive.
- Respec Often: The game is reportedly generous with re-slotting your Medalum. If a boss is killing you, it’s not because you aren’t strong enough—it’s because your Medalum isn’t tuned to that boss's specific attack patterns.
The Paintress is coming for the 33s. Your only real chance is to make sure your gear is better than her art. Keep your shards polished and your parry finger ready.
