Challenge the Metal Sea

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

▲Since the level has increased by 4, it's 108x4 for a +432 bonus.
Use unwanted Tactical Memories as materials to level up your equipped Memories. Stats increase by the same amount as their initial value each time the level goes up by 1, and an option is added or enhanced every 4 levels.
| Note! | The maximum level for a Tactical Memory is 20. |
|---|
Enhance From Low Rarity

We recommend actively enhancing Tactical Memories, even if they are low rarity. This is because when using an enhanced Memory as material, you gain EXP equivalent to its enhancement level, so the Memories used for enhancement are not wasted.
EXP Gained by Rarity
| Rarity | ![]() | ![]() | ![]() | ![]() | ![]() | ![]() |
|---|---|---|---|---|---|---|
| EXP | 10 | 15 | 30 | 50 | 100 | 200 |
Recommended to Enhance Low-Cost SSRs

Until you get the GR you want, it's usually best to prioritize increasing your immediate Battle Power by enhancing and equipping SSRs. Since Memories are easier to obtain and have a lower level cap than Crests, enhance and use SSRs instead of Rs or SRs.
Increase in Required EXP Per Level
| Rarity | ![]() | ![]() | ![]() | ![]() | ![]() | ![]() |
|---|---|---|---|---|---|---|
| Increase Amount | +10 | +15 | +30 | +50 | +100 | +200 |
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.
Recommended Stats for Slots 4-6
| Slot | Stats |
|---|---|
| 4 | - Normal Attack Damege - Skill Damage - Boss Damage |
| 5 | - Critical Rate - Skill Critical Rate |
| 6 | - Critical Damage - Skill Critical Damage - Normal Attack Damege UP - Skill Damage UP - Critical Damage UP |
It is recommended to focus on Normal Attack, Skill, and Critical stats to boost your overall damage output. Also, it's a good idea to carefully select/raise Boss Damage in Slot 4 for boss battles and switch to it when needed.
| Note! | By supplementing Critical Rate in Slot 5, you'll have more flexibility to allocate Gear options to Stun Rate. |

Select the Best Option Values and Types

You will randomly obtain 0 to 4 options upon acquisition, and the higher the rarity, the more you will have from the start. Also, because the values can differ even for the same effect, you can farm until you finally get your desired combination of Tactical Memories.
