Challenges can be accessed via [Menu] - [Challenges].

In Challenges, you have to complete certain objectives in instance-type stages. New Challenge stages will become available as you raise the Company LV and make progress in Chronicles.

Challenges can be divided into two categories. Training is the first category and features Challenge stages very similar to tutorials in nature.

These stages walk you through the basics of combat—Ships’ Mobility, relative weaknesses and strengths, the conditions that determine whether a Counterattack is triggered, and so on—as well as less obvious mechanics. As the main goal of these stages is to learn how the game works, Auto Combat is disabled and you are required to achieve certain objectives manually.

They are designed to be easy and usually offer useful rewards such as Mate Gear and Ducats, so you should complete them as soon as you can while taking into consideration their Suggested Combat Powers.

Each Challenge is divided into several difficulty levels, and each difficulty level has different objectives. The first reward is offered only when you clear a Challenge for the first time. You may complete the same Challenge more than once, but subsequent completions will only yield Ducats.

In the second category are the stages where you can freely engage the powerful fleets you encounter during scenarios in combat. Auto Combat is enabled for these stages.

As you will be pitted against some powerful enemies, you may not be able to complete these until you are truly ready. The Suggested Combat Power is much higher for these stages, but the potential rewards are likewise much more valuable.

Each Challenge is divided into several difficulty levels, and in most cases, the main objective is to defeat the enemy Fleet.

As these stages unfold in the same manner as regular Combat, you can earn additional rewards by accomplishing Additional Goals.

You are guaranteed to get the initial reward when you clear a Challenge for the first time. You may complete the same Challenge more than once, but it will only yield random rewards after the initial completion.
