Memory Bonds
Obtained mainly through Adventure Mode by earning full-star completion rewards. They provide direct combat bonuses like increased attack, damage %, and critical damage.
The Bond System is an important progression feature that provide significant combat bonuses, including increased attack, damage, critical damage, and other powerful effects that can greatly improve a character's performance. Each Bond grants unique bonuses during battle, and some Bonds are specifically stronger for certain characters or playstyles. Bonds are special enhancements equipped through the Stamp menu on a character.

Bonds are another option to improve our characters, but a little different from other enhancement methods like Weapon Stamps or Set Stamps. Each Bond grants unique bonuses during battle, and some Bonds are specifically stronger for certain characters or playstyles. Bonds can be leveled up by obtaining additional Bond fragments. There are two types of Bonds:
Obtained mainly through Adventure Mode by earning full-star completion rewards. They provide direct combat bonuses like increased attack, damage %, and critical damage.
Obtained through the Deploy system. They improve resource acquisition — extra rewards from Fund Collection, Patrol of the World, Hollow Hunt, and Academy Training.
Complete Adventure chapters with full stars to unlock Memory Bonds and their fragments.
Run Deploy missions daily to collect Regular Bond fragments. Use your free refreshes to reroll for better Bond rewards.
Upgrade Bonds whenever fragments become available. A well-developed Bond collection provides substantial advantages in both PvE and endgame ranking.
SR Memory Bonds are the entry-level combat Bonds. They provide solid stat boosts and are easier to obtain through early Adventure chapters. Equip these to boost your team's Attack, Skill damage, damage types, and Critical Damage.

Regular Bonds provide account-wide progression bonuses rather than direct combat power. Their effects improve resource farming and various game modes. Because many of these bonuses improve resource acquisition, upgrading Regular Bonds can significantly accelerate account progression.
