Star Savior Reroll Tier List: Best Units To Aim For On Day One

Star Savior Artwork 8

Rerolling in Star Savior is all about securing at least one “National Power” carry plus a top-tier support or tank so your account feels strong from the tutorial onwards. Because a full reroll cycle can take 25–35 minutes, aim for 1–2 premium units and stop rather than chasing perfection.

Day-one reroll priorities (short list)

Most reroll and tier-list guides agree on five “Tier 0 / National Power” units that are worth resetting for.

Top reroll targets (Tier 0 / SS):

PrioritySaviorRole / AttributeWhy you reroll for them (summary)
1LunaCaster / OrderBest AoE farmer and story clearer; binds enemies and shreds waves and elites. 
2SmileRanger / StarFast single-target DPS with huge fixed defence-down, enabling one-turn boss kills. 
3KiraAssassin / SunStealth-based boss killer that cuts enemy action gauges and avoids targeting. 
4AsellaStriker / MoonFlexible AoE + single-target damage; ideal “first carry” for story and farming. 
5LydiaRanger / ChaosWide AoE plus effect-resist shred, making all debuffs and CC more reliable. 

If you can lock in any 1–2 of these on day one, you are already well ahead of most accounts.

Best supporting picks to pair with your carry

After one Tier 0 damage dealer, your next priority is a strong sustain or tank so you can push harder content safely.

God Tier supports/tanks (fantastic reroll “second hits”):

  • Serpent (Supporter / Sun): Nullifies enemy skill damage once per ally and auto-heals the lowest HP target; widely recommended as the best survival support in hard PvE.
  • Harley (Defender / Sun): Frontline tank that buffs allies’ defence and speed while providing ignite stacks; strong anchor for aggressive teams.
  • Lily (Caster / Moon): Attack-scaling shields plus attack-down debuff, giving both protection and damage reduction.
  • Dana (Caster / Star): Team-wide attack buffs and enemy speed debuffs while still dealing AoE damage; blends support and DPS.
  • Frey (Supporter / Star): Free but rated Tier 1/S in lists; excellent healer/shielder and worth keeping if she shows up with a top damage dealer.

Tier 1 damage/tank backups (still excellent reroll outcomes):

  • Charles, Carmen, Epindel, Tanya – strong DPS/tank options that round out teams even if you miss a Tier 0.
  • Vesta (SR tank) and Bella (SR healer) – great if you pull them alongside a Tier 0 DPS on an otherwise average account.

In practice, many guides recommend stopping rerolls once you get:

  • 1× Tier 0 damage dealer (Luna / Smile / Kira / Asella / Lydia)
  • plus either Serpent, Harley, Lily, Dana, Frey, Carmen, or Charles.

Practical reroll goals and when to stop

Given the long reroll time and generous launch pulls, most JP/KR resources suggest these realistic targets:

  • Ideal outcome (whale reroll standard):
    • 2× Tier 0 units (for example, Luna + Smile, or Luna + Kira)
    • plus 1 God Tier support/tank (Serpent/Harley/Lily/Dana)
  • Strong, sensible outcome (recommended for most players):
    • 1× Tier 0 unit
    • plus 1 top support/tank (Serpent, Harley, Lily, Dana, Frey, or Carmen/Charles)
  • Good enough (stop here if tired of rerolling):
    • 1× Tier 0 or high Tier 1 carry
    • and decent SR sustain (Vesta, Bella)

Because launch events and story rewards give over 500 tickets and multiple guaranteed SSRs over time, chasing more than one Tier 0 can lead to burnout without being strictly necessary. Securing a single “National Power” carry and a solid support on day one gives you a powerful foundation that later SSRs and selection tickets can build on.
