Attack, or ATK for short, represents how much damage that the unit deals after the target's defenses are factored in. HP recovery, such as that of Medic Operators, is also determined by ATK. For more information, see Damage.
Enemies' ATK values are not numerically shown unlike those of Operators and summons, instead displayed as one of the following ten ratings which roughly indicates their amount:
| SS | >5000 |
|---|---|
| S+ | 3000 – 5000 |
| S | 2000 – 3000 |
| A+ | 1500 – 2000 |
| A | 1000 – 1500 |
| B+ | 700 – 1000 |
| B | 500 – 700 |
| C | 300 – 500 |
| D | 200 – 300 |
| E | <200 |
Modifiers[edit]
Buffs[edit]
Many Operators have the ability to increase the ATK of friendly units (including themselves), but those will not be listed on this page due to their numbers. This also applies to enemies with the ability to increase the ATK of other enemies and themselves.
Two of the most notable examples are the ATK/Healing Up and Swift Strike skills, which increase the user's ATK for their duration.
