Miriam (Afterimage)Build and Guide

Last Updated - August 11, 2025

Miriam (Afterimage) is a Fairy DEX Assassin that can swap between her 2 modes based on where she is placed in the formation. Placed on the front line, she’s a fairly tanky disruptor, and on the backline she’s an all-out glass cannon.

• Passive: Line Reversal – Miriam gains different effects based on where she is placed in the team.

  • Front Row: Miriam gains a shield at the start of the battle, regaining a shield every 10 hits. She also lowers the Resistances of all enemies within 3m of her.

  • Back Row: Miriam gains 30% Damage dealt and 30% Speed, but takes 10% more damage.

• S1: Surging Pierce – Miriam dashes to the enemy with the lowest HP, dealing damage and dispelling 2 buffs. Front Row: Miriam takes less damage for a short duration and gains a shield afterwards. Back Row: Attack deals more damage with guarantee to crit.

• S2: Dagger Blink – Miriam attacks the closest enemy, dealing damage and stunning. Front Row: Miriam taunts all enemies within 3.5m of her and decreases their ATK. Back Row: Attack deals more damage.

• Main: Detonating Spear – Miriam deals damage to the nearest target and AOE damage to all enemies within 3m, stunning them. Knocks away all enemies besides the main target. This attack cannot be evaded.

• Ultimate: Blink Strike – Miriam attacks the enemy with the highest ATK. Gains Limiter Removal - +40% Speed. All subskills consume 500 mana and deal additional damage.

• Artifact Skill: Emergency Blink – Miriam’s normal attacks deal additional Burn damage and apply a 4 second Burn. (at L+ and higher) Upon taking fatal damage, negates that damage, and she returns to her formation and recovers HP. Miriam permanently deals less damage for the rest of the fight, and her next action is changed to S1 – Surging Piece.

Miriam presents players with the pretty elf assassin equivalent of the Trolley problem – do you want to play funny tricks on the enemy or just kill them where they stand? Unlike most other dual mode characters, Steampunk Miriam is actually competent with both modes. Miriam’s base kit is very good at immediately going after a squishy backline DPS and either killing the target ASAP or disrupting them long enough for your other souls to finish the job. And if that is not enough, Miriam’s artifact at Legend+ gives her a one-time “Resist Death” and lets her make a second attempt. Miriam is certainly a strong and versatile unit and will likely be a battlefront staple moving forward.

Miriam’s kit also functions very well against most raids. Her taunt, resistance shred, attack reduction and constant burn application allow her to excel against the Dark Knight, Charite, and Gaia raids as a support. She can also have a go at being a powerful DPS herself with tons of additional bonus damage, a whopping 70% speed buff and damage dealt buffs, although it remains to see if she will excel in that arena.

Synergies and Weaknesses

Miriam is quite starved for Crit Rate and ATK buffs and would really appreciate support from her allies in that department. She is also quite squishy outside of her shield and frankly small Damage Reduction and it doesn’t take much to put her down if she gets focused, especially as a melee Assassin. Defensive supporters like Eve and Wheri, give Miriam enough longevity to finish the job, while tanks like Claire and Honglan (Peerless) help draw attention away from Miriam.

Her small burn and debuff package also makes her an excellent slot in for the already burgeoning Burn comp; with easy access to Burn Amp and even DoT Damage amp from Rebecca.

Investment

Miriam already has access to her base utilities at lower ascensions. We’ve tested her at Eternal+ Ascension and Epic+ Artifact, and while her Front Row mode is competent enough at that stage, to maximise her Back Row mode, we always recommend Origin Ascension and Legend+ Artifact minimum to unlock her Resist Death skill on her Artifact.

Further investment on her Artifact and Ascension will greatly improve Miriam’s personal DPS.

Conclusion

Players who went deep on the Nia banner are being treated to dessert at this point, being presented with an excellent Assassin soul that can play support alongside their Nia or be the carry DPS for a 2nd team. She is an excellent pickup for many players, both new and old with a month-long banner alongside her own dedicated event.
