The Expedition 33 mechanics for weapon upgrades are very important as you face the challenging world ahead. Finding materials from battles and shops makes each weapon stronger and more powerful. Besides that, reaching weapon levels at 4, 10, and 20 unlocks the weapons’ special perks that you can use to enhance your fighting skills. Players get rewarded based on their strategic thinking rather than choosing them randomly.

1. Urnaro – The Ultimate Break Weapon

Out of all the choices, Monoco’s Urnaro is the most powerful upgrade you can choose in the game. You can obtain this earth-element weapon once you defeat the Chromatic Glaise on Sky Island. As soon as you break an enemy, the Almighty Mask instantly provides two extra energy points to your teammates.

Furthermore, when the Urnaro is completely upgraded, it does more damage when a unit breaks. As a result, Monaco is able to take charge by supporting every member of the team. This makes Monoco a break-focused powerhouse who supports the entire team, and some players strategically plan their party to take full advantage of the weapon’s special traits. 

2. Sireso – Team Support Excellence

The Sireso transforms Verso from a solo damage dealer into a party enabler. You acquire this blade by fighting the Chromatic Greatsword Cultist in Sirene. Instead of boosting Verso’s personal Perfection bonuses, upgrades redirect benefits to teammates.

Additionally, Sireso’s upgrade makes the players use less AP for their support Skills while engaging in combat. In this way, Verso can maintain steady buffs to the team while dealing respectable damage. Players who are smart will know to use this weapon to form a balance in their party teams. This makes as one of great weapon upgrades to prioritize in Expedition 33.

3. Saperim – Lightning Strike Mastery

When players upgrade the Lightning from Lune’s Saperim to its maximum level, it becomes dangerous. To obtain this weapon, you can defeat random enemies on a beach east of Sirene. The weapon ignites a lightning that causes damaging patterns that harm groups of enemies that spread to the formation.

Additionally, upgrading the weapon increases its Gradient Attacks and Gradient Counters by a large margin compared to their base number. When needed, these abilities work like limit breaks, dealing a huge amount of damage in crucial scenarios. Also, top players are able to use these attacks perfectly timed to gain the upper hand in combat.

4. Medalum – Early Game Domination

Through the Gestral Village tournament arena, Maelle’s Medalum gives great advantage in the first stage of the game. Once upgrades are ready, you get the Virtuose Stance, which makes your attacks much stronger at once. If you use this stance, you bring out Maelle’s best fighting skills during the game.

When used with assault techniques, the weapon can cause the enemy to burn more often. As soon as you get Maelle and keep improving her with the latest gears, she becomes almost unbeatable. Those who use this weapon mostly have an edge when dealing with mid-game battles.

5. Litheson – Battlefield Control

Sciel’s Litheson is highly tactical, as it gives extra speed and lets the player debuff enemies. After you beat the optional Clair Obscur boss, you can get this weapon from inside The Monolith. You can speed up your allies and slow down opponents much more after investing in upgrade modules.

It is the tarot card combination and when Sciel uses the weapon that make its function successful. Expert players can manipulate the whole battle flow using Litheson, which has been improved. This lets you take on tough situations using better management of your actions.

6. Lithelim – Dark Element Surprise

Lune’s Lithelim brings unexpected dark element damage to her typically light-based spell arsenal. The weapon appears in ruined Lumiere during the game’s final stages. Upgrades unlock unique dark magic combinations unavailable through other weapons.

This creates interesting tactical opportunities for players willing to experiment with unconventional builds. The dark element often catches enemies unprepared, especially those resistant to light magic. Late-game players appreciate this weapon’s versatility and surprise factor.

7. Joyaro – Lightning Wheel Power

Before you can get the Joyaro, you must fight and defeat the Ultimate Sakapatate in Endless Night Sanctuary. This lightning weapon works perfectly with Monoco’s mask wheel system for enhancing attacks. After killing monsters, the weapon learns abilities, like a Blue Mage in the game Final Fantasy.

Upgrading your engines boosts the lightning abilities and also enhances Monoco’s skill set a lot. In turn, the character is able to face a variety of enemies effectively. The weapon is very useful and can be used in many battlefield scenarios by devoted players.

8. Facesum – Burn Damage Amplifier

Despite not possessing a fire element, the Facesum improves burn damage after being upgraded. After defeating the Chromatic Boucheclier, the Isle of the Eyes provides this weapon.
Combining it with Verso’s Corpeso creates a deadly weapon, as it can easily lessen the opponents’ health with its burn combinations.

Strategic team members use many damage-over-time tricks to make the fight go quickly against their enemies. With weapon upgrades, burn builds get much stronger and become very effective. This way of playing makes it seem like most bosses in the game are easy to deal with.

9. Corpeso – Late Game Perfection

Later on (in Dark Shore), Corpeso, who is Verso’s form, is revealed by the mystery cloaked creatures.  Using Verso’s Perfection adds more power to the weapon, making it even more attacking-oriented. Because Verso got the term later, this is a stronger fit for him than Gustave.

Corpeso at its maximum potential regularly deals a lot of damage, preparing for fire combinations that can completely destroy enemies. People who get to the final stages of the game usually like this weapon’s dependability. The money spent on upgrades helps greatly during battles with the game’s final bosses.

10. Algueron – Ice Control Specialist

Mastering ice element skills and making strategic improvements in Algueron helps Sciel to use Free Aim successfully. A Mandelgo’s Shop in the Old Lumiere area makes it simple to buy this weapon early. It is the Foretell cards that sustain Sciel’s special benefits linked with tarot.

When Twilight Mode is activated with several Foretell cards, it increases the damage your deck does. Another thing that can make you stronger is upgrading your basic attacks and unique spells. Thus, Algueron suits players who like games that focus on tactical card-based fights.
