My first pull of the global launch froze my thumb over the screen. The banner spit a 5-star and my chat thread lit up with frantic reroll advice. I remember thinking: did I just win or inherit a responsibility?
I write this as someone who has watched dozens of launches spin into panic. You want a clear plan you can use at hour one and at level 60, and I’ll show you where to spend patience and where to burn time.
Complete Mongil Star Dive characters tier list
I’ve read hundreds of roster screenshots on Discord and Reddit where players brag or commiserate about a single pull. In the first week, rarity matters, but role and pairing matter more.
In Mongil Star Dive characters come in 4-star and 5-star rarities. The 5-star options are rarer, but not every 5-star deserves the same slot in your squad. Below I separate characters into four tiers so you can decide whether your opening roster is a vault or a paperweight.
- S-tier: Overpowered in the current meta — build teams around these.
- A-tier: Strong and versatile; great if you don’t have an S-tier lineup yet.
- B-tier: Playable with investment, often niche or support-dependent.
- C-tier: Keep while you grind, then replace as soon as you can.
S-tier
| Character | Element | Reason |
|---|---|---|
| Esther | Wind | One of the best assassins. Her smokescreen forces enemies to lose targets and her enhanced attacks multi-hit. Esther’s kit is a Swiss army knife: flexible offense, evasive setup, and a Support skill that auto-triggers when an ally takes damage. |
| Jiwon | Wind | Elite support that amplifies Wind teams and pairs exceptionally with Esther. She lowers stamina costs, increases Wind damage, and her own attacks scale her buffs — a lighthouse for team consistency. |
| Flare | Fire | Fire destroyer who applies strong debuffs and buffs allied Fire DPS. Great AoE potential and hybrid utility for clearing packs and strengthening a primary carry. |
| Gabi | Earth | Specialized boss-killer. Uses a rhythm of Basic attacks and skills to exploit enemy vulnerabilities and can convert enemy special attacks into her own damage spikes. |
A-tier
| Character | Element | Reason |
|---|---|---|
| Francis | Earth | 4-star support that’s easy to pull and level. Extremely flexible: buffs tag-in partners and fills multiple roles when roster depth is thin. |
| Penny | Lightning | Ranged skirmisher whose Special skills scale with Crit Rate. Pokes safely from distance and ramps damage through specials. |
| Ophelia | Ice | Strong Ice DPS. She self-buffs to raise Crit Rate and sustains those buffs through Special Skill inputs, making her reliable when built correctly. |
B-tier
| Character | Element | Reason |
|---|---|---|
| Snagun | Wind | Situational; offers utility in specific compositions but needs support to shine. |
| Ellie | Earth | Hard to manage—she prefers off-field play and delivers value primarily through tag-in Neutralization buffs. |
| Benjamin | Lightning | Support Skill creates AoE tag-ins on Special Skill use, which can be powerful, but long cooldowns limit consistency. |
| Yeownhwa | Lightning | AoE sub-DPS potential but demands heavy investment; cooldowns on core abilities are long at base. |
| Cloud | Ice | Builds Ice Crystals and deals AoE stagger damage. Solid once leveled, but requires resources to reach peak value. |
| Angel | Fire | Good secondary DPS and pack clearer; buffs Fire allies but struggles against single-target bosses. |
C-tier
These characters are functional early, but better options exist once you have resources.
- Leeho
- Verna
- Dalay
- Bonie
- Reina
- Sera
How should I reroll in Mongil Star Dive?
Players flood Discord and Twitter during launches asking this. My rule: reroll only if you need an S-tier core for your first team; otherwise, pick a reliable A-tier and start collecting. Rerolling aggressively can cost hours better spent learning mechanics and joining community channels on Reddit and official Discord where fellow players share synergy guides and banner analytics.
Which characters are worth investing in first?
Invest in characters who change how your team plays: S-tier cores (Esther, Jiwon, Flare, Gabi) then supporting A-tier units that complement them. Use YouTube creators and community spreadsheets to compare skill scalings and artifact recommendations before spending resources.
Are 4-star characters worth keeping?
Yes. 4-star supporters like Francis provide immediate stability while you wait for 5-star pieces. They’re easier to level and often fill essential roles without demanding investment equivalent to 5-star carries.
If you want tactical resources: use gacha tracker tools, community spreadsheets on Google Sheets, and the official Discord to time your pulls and to watch for pity resets.
Final thought: your first week is about choices that compound—who you promote, who you feed, who you ignore. Which roster move will you bank your first hundred hours on?
