Mongil Star Dive Reroll Guide: Best Characters and Fastest Routes

Why your first pull matters more than you think

Mongil: Star Dive throws you into fast-paced combat almost immediately, and the characters you start with directly affect how smoothly you clear early and mid-game content. The good news: the tutorial is short, the starter banner guarantees a 5-star within 20 pulls, and the whole reroll loop takes as little as 5 to 15 minutes depending on how aggressively you skip cutscenes. Knowing which characters to target and which route to take can save you hours of grinding later.

Is rerolling worth it in Mongil: Star Dive?

Yes, and the math is straightforward. New players receive 20 free pulls on the New Expedition banner, which guarantees one of the six permanent 5-star characters. According to Game8's reroll guide (updated April 19, 2026), the tutorial takes around 15 minutes to complete before the gacha system unlocks. That's a short time investment for a potentially account-defining character.

The one catch: you cannot delete your account and reuse the same email. Account deletion takes 30 days to process, as confirmed by both Pocket Tactics and Game8. Every reroll attempt requires a fresh account with a different email or login method.

How to reroll in Mongil: Star Dive

Step-by-step reroll process

The process is consistent across Android, iOS, and PC emulators. Here's the core loop:

1. Create a new account using a separate email or login method and launch the game.
2. At the difficulty selection screen, choose Path of Dawn. This setting makes enemies easier to defeat and speeds up tutorial progression. The difficulty can be changed at any time afterward.
3. Push through the tutorial. You'll be forced to pull on the A New Friend for a New Journey tutorial banner, which grants one random 4-star character. This is not your reroll pull.
4. Defeat Forkmugger and reach the Monster Tamers Gathering Hub to unlock the Recruit system.
5. Check your Mail for any pre-registration rewards, redeem code rewards, or event currency before pulling.
6. Spend all available pulls on the New Expedition banner. This is your primary reroll anchor.
7. Evaluate your results. Keep the account if you land a target character. If not, log out and repeat with a new account.

Rerolling on emulator

If you want to run multiple rerolls simultaneously, an Android emulator on PC is the fastest method. Tools like BlueStacks, LDPlayer, or MEmu all support a Multi-Instance Manager, which lets you run several copies of the game at once. Set up each instance with a separate account, play through the tutorial on all of them in parallel, and compare results before committing to one. This approach requires multiple email addresses but dramatically cuts down total reroll time, according to GamingOnPhone's reroll guide.

What are the two reroll variations?

Kaiden.gg outlines two distinct approaches depending on how much time you want to spend per reset:

Variation 1 means completing up to the "To The Monster Tamers!" quest, claiming Mail rewards, and rolling on New Expedition. It's the fastest loop and covers most reroll targets.

Variation 2 pushes further to the "Scrubs Up, Everyone" quest, which unlocks the Events system. This grants 1 to 2 Compasses of Destiny (the limited banner currency), giving you 3 to 4 additional attempts on the current limited banner. Worth doing if you're specifically chasing Esther.

Best characters to reroll for

Top reroll character targets

Who should you target?

All six permanent 5-stars are viable, but some have clearer advantages at launch. Here's a breakdown based on the reroll tier lists from Game8, Pocket Tactics, and Kaiden.gg:

Esther is the top reroll target if you're willing to spend extra time. She's a limited 5-star Wind Assassin who performs well in both boss fights and general combat. Game8 places her in the SS tier for rerolling. The downside: she's only accessible via Compasses of Destiny on the limited banner, and her 5-star pull rate is 1%. Chasing Esther exclusively can turn rerolling into a grind that delays actual progression. Only commit to this if you're set on a Wind-focused team.

Jiwon is the strongest standard-banner reroll for players who want long-term utility. She's a 5-star Wind Support who provides damage buffs, grouping, Affliction, and Stamina buffs for Wind-attribute units. According to Kaiden.gg, she pairs naturally with Sangun or Esther as Wind main DPS options. Game8 ranks her in the SS tier alongside Esther for reroll purposes.

Gabi is the best immediate DPS option from the permanent pool. She's an Earth Fighter with solid AoE on auto attacks and a strong ultimate, and she has natural support synergy with Francis (who you get for free via pre-registration mail). LDShop's guide highlights her as the standout practical permanent-banner target for players who want carry value from day one.

Flare is a Fire Destroyer who specializes in breaking boss stagger gauges. Kaiden.gg notes there's currently a lack of strong Destroyers in the roster, which makes her the default best in her role. Her AoE is serviceable but not exceptional. A solid pick, though not the first recommendation if Jiwon or Gabi are available.

Ophelia is an Ice Fighter with quick combo chains and a straightforward nuke ultimate. Kaiden.gg compares her kit to fast melee characters from other action games. She's simple to play but can feel limiting as a pure melee unit in certain encounters.

Penny is a Lightning Bow User with quick cooldowns and decent AoE. Her boss fight potential is weaker than the other 5-stars on this list, making her the least prioritized reroll target among the standard pool, according to Kaiden.gg.

How does the Mongil: Star Dive gacha system work?

Gacha currency overview

Mongil: Star Dive uses two primary pull currencies. Compass of Promise is used on standard banners, while Compass of Destiny is required for limited banners. During rerolling, you may also encounter Threads of Promise, Starlight Crystals, and Primordial Stars depending on which rewards you claim and convert.

The current launch banners include Maid & Clover Mascot (featuring Esther) and Wind-Harboring Broom (her artifact banner), alongside permanent banners Eternal Promise, Promised Crest, New Expedition, and New Friends, according to LDShop's gacha system breakdown.

Key rates and pity numbers from LDShop's guide:

• 5-star pull rate: 1% on Event Recruit and Event Artifact banners
• 4-star pull rate: 6%
• 4-star guaranteed: every 10 pulls
• Event Recruit pity: 90 pulls
• Event Artifact pity: 80 pulls
• Rate-up bonus begins: 75 pulls on Recruit banners, 65 pulls on Artifact banners
• Pity carries over between banners of the same type

For rerolling specifically, the New Expedition banner's 20-pull 5-star guarantee at a discounted starter rate is the most player-friendly mechanic in the game's gacha setup. Use it as your primary reroll vehicle rather than spending early Compasses of Destiny on the limited banner unless you're specifically running Variation 2.

When should you stop rerolling?

Stop immediately if you land Esther. For standard-banner rerolls, stopping on Jiwon or Gabi is already a strong result. Landing one top-tier 5-star plus the guaranteed Reina (4-star, awarded on your first tutorial pull) gives you a functional early team. Spending too many sessions chasing a perfect account slows your actual progression more than a slightly lower-tier starting character would.
