Leveling up and strengthening your characters in BLEACH: Soul Resonance is essential for keeping up with rising combat power requirements as you progress through the story, challenges, and raids. Nearly every upgrade system in this RPG contributes some form of raw stat gain or unlocks deeper mechanics such as skill enhancements or ascension bonuses. Understanding how these systems connect will help you get the most value out of your resources, especially early on when materials are limited.

In this guide, we’ll break down every major way to upgrade a character, how each system works, and why each one matters for long-term progression.

Character Leveling

Leveling up is the simplest and most direct way to increase a character’s ATK, DEF, and HP. This is done using Insight Books, which act as EXP potions. Each book provides a fixed amount of experience:

• Member’s Insight: +500 EXP
• Seat Officer’s Insight: +3,000 EXP
• Captain’s Insight: +10,000 EXP
• Head Captain’s Insight: +20,000 EXP

These items drop from story missions, patrols, events, and other repeatable content, or even by using BLEACH: Soul Resonance redeem codes. As characters level up, they gain baseline stat increases that improve both survivability and overall damage output. Early levels come cheaply, but later levels require significantly more EXP, so prioritize your primary DPS or your main team of three characters rather than spreading books across too many units.

Weapon Upgrading

Each character has a dedicated weapon shown on their character screen. Upgrading the weapon increases its own stat values, which directly boosts the character’s ATK, HP, and DEF. Weapon upgrades require Tamahagane, which comes in several tiers:

• Tamahagane I: +500 Weapon EXP
• Tamahagane II: +2,000 Weapon EXP
• Tamahagane III: +5,000 Weapon EXP
• Tamahagane IV: +10,000 Weapon EXP

These materials are mostly obtained from hollow hunts, challenges, and upgrade-stage farming. Weapon levels significantly influence a unit’s overall power and often provide one of the best early damage boosts relative to resource investment.

Stamps

Stamps function as weapon-bound enhancement cards that grant bonus stats and sometimes special effects. They come in rarities just like characters (R, SR, SSR) and can be rolled through the gacha. Each weapon has a slot for a stamp, and equipping one provides immediate stat boosts.

You can also upgrade stamps by fusing duplicate copies, which increases their stats even further. Since SSR stamps are tied to specific characters, obtaining the proper stamp for your main DPS should be a high priority, especially because stamp bonuses scale extremely well in the late game.

Skill Upgrading

Skills can be upgraded through materials obtained in story missions, events, and various dungeons. Raising your skill levels improves their damage, duration, healing power, or utility depending on the character. In general:

• Ultimate skills offer the biggest impact per level.
• Core passives can drastically change how a character functions.
• Basic and active skills scale steadily and help increase consistency.

Skill upgrading should be focused on your highest-priority units first, as materials are limited early on.

Ascension

Ascension is the long-term progression system that increases a unit’s star level by consuming character duplicates obtained from the gacha. Ascension unlocks powerful benefits:

• Large ATK/DEF/HP increases
• New passive abilities or boundary skills
• Higher skill caps
• Occasionally new traits or improved versions of existing skills

Ascension materials are character-specific, meaning duplicates automatically convert into ascension items for that unit. This makes every extra pull valuable, even if you already own the character.

Upgrading your characters in BLEACH: Soul Resonance is a multi-layered process that rewards steady investment into a small core team. After all, even top-tier Soul Resonance characters are mostly useless without upgrades. Leveling provides raw stats, weapon upgrades push your damage higher, stamps reinforce your build with even bigger bonuses, skills expand your combat effectiveness, and ascension unlocks a character’s full potential.
