Hello Commanders.

Following the February 24 update, Command Tank skills are now displayed up to Level 7.

​​

​Please note that Skill Levels 6 and 7 cannot be increased through Command Tank leveling or by using skill enhancement materials. Instead, these levels can only be achieved through Engine Modification.

For more details, please refer below.​

■ Command Tank Skill Levels 6 and 7 Conditions​​​​

​- These levels cannot be reached through standard skill upgrades.

- When a skill is at Level 5, you must obtain a Main Skill or Sub Skill level buff through Engine Modification in order to apply Levels 6 and 7.

[You can check here the list of buffs obtainable through modification!]​

We hope this information has been helpful, and we will continue striving to provide useful guidance in the future.

Thank you.​​
