Overall Base progression

Base level does increase your stats

The client applies the Base possession buff to allied characters. Each Base level contributes the same three bonuses, while a separate player aura is selected from the level brackets below.

Loaded percentages and native application path verified
Every Base level+4% ATK BonusAlso +4% DEF Bonus and +4% HP Bonus.
Example: Base Lv.54+216% to all three BonusesThe selected player aura at this level is 18% Boss Damage DOWN.
Simple ruleATK / DEF / HP Bonus = Base level × 4%

For example, 54 × 4% = 216%. This is a multiplier stat, not 216 raw ATK, DEF, or HP.

Individual Buddy progression

Stars improve stats and skills

Every star after ★1 applies that Buddy's per-star growth values. The table shows the first star of each skill tier.

Raw Attack = Base Attack + Attack growth × (stars − 1)

Attack Bonus = Attack Bonus growth × (stars − 1)

Effective Attack = Raw Attack × (1 + Attack Bonus)

How the percentage values are read

The table stores Attack Bonus growth as numbers such as 20. The client divides percent-type stats by 100 after loading, so 20 means +20% per star—not +2,000%.

Shared star growth

Stats every Buddy profile shares

Only Attack and Attack Bonus differ between the listed Buddy profiles.

Every Buddy is marked No Targeting in the client table. The 1 HP and 1 Defense entries should not be read as a normal player-style survivability model.

All percentages shown here include the client's load-time conversion. For example, a stored Normal Attack Damage value of 10 is displayed as 10%.
