Reroll Guide — Best Targets and Stop Conditions

What rerolling actually buys you

Rerolling in Mongil is the practice of running a fresh account's opening hours, claiming the new-player summon currency, and re-creating the account if the resulting pulls do not give a viable endgame foundation.

A clean re-run takes roughly 8 to 10 minutes depending on how aggressively you skip cutscenes, so the per-attempt cost is real but bounded — most players who commit to the loop will see between four and ten attempts before stopping.

Your pull budget on a fresh account

A fresh account gets enough new-player currency for 22 pulls in total: 20 on the Permanent Banner and 2 on the Limited-Time Banner. That budget is fixed — you will not get more by playing the prologue more carefully.

The Permanent Banner has a special variant called New Expedition that guarantees one permanent 5★ character within 20 pulls. For reroll purposes that is the banner you want to spend the 20 perm-banner pulls on, because it removes the variance from your one guaranteed 5★ outcome. The two limited-banner pulls are pure rate-up flavour — you can re-pull them on the active rate-up banner whose featured character matters to you.

Priority targets

For the May 2026 roster the following targets stand out — listed with the role and element each one fills, so you can pick based on your own roster gap rather than chasing a name:

• Esther — SSR Slayer (Wind). The premium high-roll reroll target for accounts willing to keep going on the limited banner.
• Mina — SSR Brawler (Fire). Featured on current rate-up at the time of writing, and a strong reroll target as a limited DPS effective against most enemy types.
• Flare — SSR Destroyer (Fire). The best Destroyer because the launch-roster Destroyer pool is shallow; her Stagger-Gauge pressure pairs cleanly with a Fire Slayer.
• Jiwon — SSR Supporter (Wind). The best long-term Permanent-Banner reroll: Supporter scarcity is the most painful gap to fix later, and Jiwon is the cleanest answer.
• Gabi — SSR Brawler (Earth). The strongest permanent-banner DPS option for players who want an aggressive launch but did not roll the limited.

Live tier snapshot

The community tier list this site maintains is re-scored against current Conquest and Rift bosses every patch. Use it as the cross-check on the named targets above — if a target above is sitting outside the top buckets here, the patch context has shifted since this guide was last written and you should treat the live snapshot as the stronger signal.

Why these names — read in roles, not tiers

The reason these five names keep coming up is not arbitrary — it is that the in-game systems push every account toward the same answer:

1. The Stagger loop hard-codes a role specialisation: Destroyers fill the Stagger Gauge fastest, Slayers deal more damage during Stagger and Burst windows. That is two of the three slots already named.
2. Counter Gauges on certain bosses can only be drained by a specific element. Failing that gauge is a wipe window, so an account that has at least one strong character per major element answers more bosses than an account that hyper-stacks one element.
3. Supporter scarcity is the most asymmetric roster gap. There are far fewer Supporters than damage characters in the launch roster, so a starter Supporter pays off across every team you ever build — which is why Jiwon is the Permanent-Banner consensus pick.

The five names above are the cleanest reads of those three rules together. If you match all five it is statistically unlikely; matching any two from {Esther, Mina, Flare, Jiwon, Gabi} is the realistic stopping line.

When to stop

Stop and commit the account when both of the following are true:

1. You have at least one S-tier limited rate-up character from the targets above (Esther, Mina or Flare).
2. You have at least one permanent 5★ from the New Expedition guarantee — ideally Jiwon (Supporter) or Gabi (Brawler) for role coverage; any of the others still moves the needle.

That account is launchable. Marginal upgrades from continued rerolling cost more time than the equivalent rate-up pulls on a live account, where you have access to per-banner pity, a steady drip of free summons and the Path-driven materials that actually scale your roster.

What not to use as a stopping signal

• One specific named character outside the target list. With 2 limited pulls and rate-up multipliers sitting where they do, single-character rerolling has no bounded sample size and will eat days of attempts.
• Multiple SSRs in the same role. Endgame content tests role coverage, not raw rarity count. Three SSR Brawlers and zero Destroyers is a starting account that cannot stagger anything.
• A specific element. Banner schedules rotate; an account that stops on a single-element preference is betting the rest of the year on that element staying relevant.
