Type matchups, terrain affinity, stat limits and the damage cap

Blue Archive attack types, armor and terrain

Every hit is multiplied by how the attacker's attack type meets the target's armor, from double damage down to half, and by the student's affinity for the stage's terrain. Each student's page lists both.

Attack type against armor type

Rows attack, columns defend. Each attack type deals double damage to one armor: Explosive into Light, Piercing into Heavy, Mystic into Special and Sonic into Elastic. Sonic also deals 150% to Special armor. Structures (barricades and other objects) take half damage from all four.

Terrain affinity

Every stage is Urban, Outdoor or Indoor, and every student has a grade for each, from D to SS. The grade scales all damage the student deals there and how well they use cover. An Exclusive Weapon at 3 stars raises one terrain by a grade.

Cover values are the game's own rating numbers, as the terrain screen prints them.

Stat limits

Buffs and debuffs stack, but the result is clamped to these ranges for students. Past the cap, more of the same buff does nothing. A single hit deals at most 4,000,000 damage. A single heal restores at most 1,000,000 HP.

Strikers and Specials

A team fields up to four Strikers and two Specials. Specials never step onto the field: they use their EX Skills from the back line, and each Striker gets a share of their stats. Raids that take larger teams pass on a smaller share.
