How To Upgrade Weapons in Lost Soul Aside

By Daniel Hidalgo | 2025-09-08 08:12:20
Lost Soul Aside has captured the attention of action-RPG enthusiasts worldwide, drawing favorable comparisons to genre giants like Devil May Cry and Final Fantasy. While its breathtaking visuals and high-octane combat are immediate draws, long-term success hinges on a deep, strategic understanding of its progression systems. Central to this is the game's unique approach to powering up your character. This guide will provide a comprehensive breakdown of how to upgrade your weapons, turning Kazer into an unstoppable force.
Unlike traditional RPGs where you might enhance gear with simple ore or currency, Lost Soul Aside employs a more nuanced system built around Accessories. These items are the absolute cornerstone of building your power and are essential for conquering the game's most challenging encounters.

Why Upgrading Your Weapons is Non-Negotiable


As you progress through Lost Soul Aside, enemies will become significantly more durable and aggressive. Relying solely on base-level weapons and player skill will eventually lead to a frustrating wall. Upgrading is not a mere option; it is a fundamental requirement for survival. A properly upgraded weapon doesn't just deal more damage—it can fundamentally alter your combat flow, increase your survivability, and unlock new strategic possibilities against different enemy types and formidable bosses.

Understanding the Core System: Weapon Assembly & Accessories


The entire upgrade process is managed through the Weapon Assembly menu, found within the Equipment tab of your main menu. This is your workshop for crafting Kazer's power.
Each weapon features six dedicated slots exclusively for equipping accessories. This generous amount of space encourages experimentation, allowing you to create highly specialized builds tailored to your playstyle or a specific boss's weaknesses.

How to Upgrade:


  • Collect Accessories: The first step is acquisition. Accessories are primarily found asvaluable loot inside chests scattered throughout the world or as rewards for defeating powerful bosses and elite enemies. Always explorethoroughly to ensure you don't miss these critical upgrades.
  • Navigate to Weapon Assembly: Open the main menu, go to the Equipment section, and select the Weapon Assembly option.
  • Equip and Enhance: Here, you will see your currently equipped weapon and its six slots.Select an empty slot and choose from the accessories in your inventory.The upgrade is applied instantly, and the weapon's core stats—such asits base damage—will be immediately boosted.
  • Strategies for a Optimized Build


    Simply slotting any accessory into a weapon is not enough. The true depth of the system lies in strategic optimization.


    • Synergy Over Randomness: Don't just equip your six highest-level accessories. Read theirdescriptions carefully. Some may boost specific types of damage, enhance defensive capabilities, or provide unique perks like healing on hit.Look for accessories that synergize with each other and the inherentstrengths of the weapon you are using.
    • Adapt to the Challenge: Lost Soul Aside encourages you to be dynamic. Don't be afraid todismantle one build to create another. If you're facing a boss that uses fire attacks, consider creating a build that prioritizes fireresistance. Having a versatile toolkit of accessories allows you toadapt on the fly.
    • Experiment Constantly: The six-slot system is designed for trial and error. The best way tounderstand what works is to test different combinations against enemiesin the field. Feel the difference in combat speed, damage output, andoverall effectiveness.


    By mastering the Weapon Assembly system and strategically leveragingaccessories, you transform from a mere participant in the game's chaosto a master of it. Forge your perfect build, sharpen your blades, andprepare to dominate the battlefields of Lost Soul Aside.
