Should You Buy the Stellar Voyage?
Great Value for Materials and Artifacts

The Stellar Voyage is a high-value purchase for players who actively play Mongil: STAR DIVE. Purchasing it significantly reduces the risk of running out of character upgrade materials while also providing access to 5★ Artifacts.
First Class for Maximum Artifact Value

The Stellar Voyage offers two paid tiers: Business Class ($7.99 USD) and First Class ($16.99 USD). While there are four types of 5★ Artifacts available, the key distinction is that Business Class grants one at random, whereas First Class allows you to select your preferred Artifact.
First Class Rewards

Purchasing First Class grants access to all rewards, including those from Business Class. Note that upgrading later costs $16.99 USD, bringing the total to $24.98 USD, which is $7.99 USD more overall, making it more cost-efficient to choose First Class upfront.
Best Artifact Picks for Exchange
Select Based on What You Own

Stellar Voyage Artifacts are designed with abilities tailored to specific Roles. They do not perform optimally when equipped on a different Role, so it is recommended to evaluate your current characters and Artifacts and exchange for one that best fits your setup.
Celestial Halo of Life Recommended

Celestial Halo of Life is a Support-focused Artifact that grants a teamwide ATK buff by simply landing an attack on an enemy. With its straightforward activation condition, it is a versatile option that can be effectively used by most Support characters.
List of Exchangeable Artifacts
| Artifact | Role and Effect |
Frenzied Struggle | [Recommended Role] Fighter - Increases Special Skill DMG by 10% - Increases Crit DMG by 4% when an attack hits - Crit DMG increase effect stacks up to 2 times |
Thunder-raising Tremors | [Recommended Role] Destroyer - Using Switch Skill increases Neutralization DMG by 7% - Landing an attack on an enemy increases ATK by 3% - ATK increase effect stacks up to 3 times |

This is a list of exchangeable Artifacts. Their effects can be further enhanced through Fusion (Awakening), so obtaining duplicates for Fusion is also a viable option.
Stellar Voyage Rewards and Prices
Business Class Comes with a Frame

The main highlights of Business Class are the icon frame and the Starry Sea Tribute. It also includes Compass of Destiny and Starlight Crystals, making it a cost-efficient option even for players focused on pulling character banners.
Large Amount of Upgrade Materials
In addition to Compass of Destiny and Starlight Crystals for limited-time banner pulls, you can obtain a large amount of upgrade and crafting materials. Compared to the free Economy Class, the materials provided are of higher rarity, allowing for smoother progression.
First Class Has a Profile Background

First Class is the higher-tier plan, allowing you to obtain more upgrade materials and rewards overall. A major benefit is that it includes an exclusive profile background and a Starry Sea Gift.
First Class Includes All Rewards
Purchasing First Class grants all rewards, including those from the 2nd row (Business Class) as well as the 3rd row rewards. While upgrading later is possible, it costs $16.99 USD, resulting in a total that is $7.99 USD higher.
How to Level the Stellar Voyage
Clear Missions That Unlock Weekly

Stellar Voyage missions unlock every Wednesday. The objectives are generally straightforward, and missions from previous weeks remain available even after a new week begins, allowing you to progress at your own pace without falling behind.
Level Up with Season-Long Missions

In addition to weekly missions, there are also season-long missions that can be completed at any time. Clearing these missions provides a significant boost to your level progression, making it suitable even if you plan to play more intensively later in the season.
Leveling by Paying Not Recommended

You can increase your Stellar Voyage level by 1, starting at a cost of 100 Primordial Stars, with the required amount scaling per level. While this can be used to secure specific rewards near a threshold, it is generally not cost-efficient and is not recommended unless necessary.
