Recommended Tactical Memory Setups
Beta 4 + Zeta 2 Setup is Recommended

▲The slot positions for the Gear are flexible.
| Set Effect | |
|---|---|
| Normal Attack Damege 8.600% | Skill Damage 4.100% |
For Tactical Memory combinations, it's recommended to equip a 4-piece Beta set and a 2-piece Zeta set to boost Normal Attack Damege and Skill Damage. This reliably increases your firepower without relying on probability factors.
Crit or Combo Are Also Options

▲The slot positions for the Gear are flexible.
| Set Effect | |
|---|---|
| Normal Attack Damege 8.600% | Critical Damage 3.500% |
If your Critical or Combo activation rate is high enough, a Beta 4 + Epsilon 2 or Beta 4 + Gamma 2 setup is also a good option. Keep the 4-piece Normal Attack Damage set and swap the 2-piece slot as you prefer.
For a Durability Build, Use Alpha 4 as a Base

▲The slot positions for the Gear are flexible.
| Set Effect | |
|---|---|
| Damage DOWN 7.100% | Normal Attack Damege 3.500% |
If you want a durability build instead of a firepower build, it's recommended to use the 4-piece Alpha set for Damage DOWN as your base. Selecting the best reduction, Resist, and recovery-type main stats increases your durability further.
| Note! | It's also an option to use a 2-piece Alpha set and a 4-piece set for firepower. |

How to Use and Enhance Tactical Memory
| 1 | ▼Equip Memories to Slots 1-6 |
|---|---|
| 2 | ▼Increase Memory Level Through Enhancement |
1. Equip Memories to Slots 1-6

Tactical Memories have 6 slots in total, so equip a Memory in each one. Your Battle Power increases based on the main stats, options, and set effects from the combination of the equipped Memories.
How to Increase Battle PowerAim for a 4-piece + 2-piece Set
| Set Effect List | |
|---|---|
Alpha | [2-Set] - Damage DOWN 2.800% [4-Set] - Damage DOWN 7.100% |
Beta | [2-Set] - Normal Attack Damege UP 3.500% [4-Set] - Normal Attack Damege UP 8.600% |
Gamma | [2-Set] - Combo Damage UP 3.500% [4-Set] - Combo Damage UP 8.600% |
Delta | [2-Set] - Counterattack Damage UP 3.500% [4-Set] - Counterattack Damage UP 8.600% |
Epsilon | [2-Set] - Critical Damage UP 3.500% [4-Set] - Critical Damage UP 8.600% |
Zeta | [2-Set] - Skill Damage UP 4.100% [4-Set] - Skill Damage UP 10.300% |
The 4-piece set effect is more than double the 2-piece effect, so aim for a 4-piece + 2-piece combination. Set effects activate when you equip Tactical Memories of the same type (color), regardless of rarity.
2. Increase Memory Level Through Enhancement

Use unwanted Tactical Memories as materials to level up your equipped Memories. Leveling up increases a Memory's main stat values, and options are enhanced or added at certain level intervals.
It's Fine to Enhance from Low Rarity

Actively enhance the Tactical Memories you have equipped. When using an already enhanced Memory as material, you will receive EXP that includes the amount it was enhanced by, so the Memories used for enhancement are not wasted.
Can Be Swapped Using the Preset Function

Tactical Memories have 10 Preset slots, so use them when you want to switch between set effects for different content. Preset names can be edited to make each one's purpose clearer.
Selecting the Best Tactical Memories
Select Main Stat Values and Types

For slots 1-3, the main stat type is fixed, so focus on selecting the best values. Since the main stats for Memories in slots 4-6 are random, you can select for both the best values and types.

| Slot 1 | - HP |
|---|---|
| Slot 2 | - ATK |
| Slot 3 | - DEF |
| Slot 4 | - Damage DOWN - Normal Attack Damege - Normal Attack Damage DOWN - Skill Damage - Skill Damage DOWN - Boss Damage - Boss Damage DOWN - Combo Damage - Combo Damage DOWN - Counterattack Damage - Counterattack Damage DOWN - Support Damage DOWN - HP Recovery - HP Recovery Amount |

|---|
▲Only confirmed effects are listed.
Select the Best Option Values and Types

You get 0 to 4 random options when you obtain a Memory. Since the values can differ even for the same effect, you can keep selecting until you get the option combination you want.
