[Dev Note] Shadow Sister: Eliminate Target

Hey there, Survivors!

We’re back again with another character rework update. Today, we’re introducing a deadly assassin who can finish the job before her enemies know what hit them—Shadow Sister Mienne.


[h3]Shadow Sisters: Serving the Light from the Darkest Places[/h3]
Mienne is a member of the Shadow Sisterhood, a covert group that’s been operating long before the explosion of Memolith. Their role? To "handle" anything that went against the doctrine of the Church—quietly, from the shadows.

While the Church preached its bright and shining teachings in public, there were always things they couldn’t deal with so openly—gray areas, borderline heresy, or problems that might become heresy down the line. That’s where the Shadow Sisters came in: To take care of things quietly, cleanly, and out of sight.

Mienne’s been doing just that—spying, gathering intel, and taking care of potential threats before they could grow into real problems. Right before the explosion, her mission was to investigate the strange darkness creeping through the Pleasure District and deal with anything suspicious. Disguised as a nurse tending to the sick, she worked undercover, passing messages to her fellow Sisters who were also operating in the area, all while chasing down the source of the corruption.



[h3]Unexpected Connection: Joining a New Party[/h3]
Before long, the Memolith exploded, cutting off the Shadow Sisterhood’s communication, and Mienne ended up completely isolated—unable to push forward or fall back. And with all kinds of evils appearing, she focused on taking them down while trying to figure out what was going on.

That’s when she spotted the Expedition team—people who were not only trying to handle the creatures but also lighting the Guiding Pillars as they went.

Still, Mienne wasn’t one to rush in. Instead of stepping out and joining them right away, she kept her distance and watched, trying to get a read about their goals and what they were capable of. Every now and then, she’d quietly leave behind a helpful item and slip away without a word.



Just as Mienne had started to build some trust in the Expedition team, they found themselves in serious danger—completely surrounded by enemies.

At that point, Mienne couldn’t just sit back and watch anymore. She stepped out of the shadows, jumped into the fight, and advised the team to use the Guiding Pillars to push back the enemy.

After a tough battle, they managed to wipe out the enemy forces together. Encouraging the team, Mienne then joins them at their Hideout—and from that moment on, becomes a playable Survivor.



[h3]A Flash of Steel in the Shadowed Darkness[/h3]
Mienne’s character is built around stealth, precision, and practicality. She’s someone who prefers working alone over relying on others—a cool-headed realist who gets the job done quietly and efficiently. She’s not just another assassin; she’s designed as a high-skill character who shines brightest when a fight unfolds exactly as planned.

Shadow Sister Mienne’s main Stat is Speed, and characters with high Speed can deal devastating surprise attack damage—far beyond what most enemies can handle. For her, Ambush isn’t just a tactic—it’s everything. That said, you can’t always ambush in every situation. If enemies are grouped too closely or if there’s a sharp-eyed foe nearby, getting the jump on them won’t be so easy.

That’s where Mienne’s core mechanic comes in: Stealth.

She has several ways to slip into the shadows. From the moment she joins the team, she comes with the skill “Hide”, which lets her enter stealth instantly at the cost of very little TP—regardless of the situation. On top of that, her unique trait “Afterimage” allows her to automatically enter stealth at the end of her turn, as long as no enemies are adjacent to her.

With this, you can chain stealth-based plays—ambushing an enemy, repositioning to stay out of reach, and slipping back into the shadows by turn’s end. If the stealth isn’t broken, you’re ready to strike again on the next turn. It’s a hit-and-fade style of gameplay that rewards patience, planning, and precision.



Of course, for Afterimage to activate, Mienne needs to keep her distance not only from enemies but also from allies. If there are characters next to her, her weakness—“Social Anxiety”—actually causes her Will to decrease.

Because of this, the Shadow Sister surprisingly needs to take a somewhat bold approach. She has to get right into the enemy’s midst, eliminate key targets, and then slip away smoothly. So, when building the Expedition team including Mienne, it’s ideal to have characters who can soak up enemy attacks and protect her.

Also, to avoid getting stuck or disadvantaged by terrain, allies, or enemies blocking her path, it’s important to equip her with a variety of movement skills that allow flexible positioning on the battlefield.



The unique traits that Mienne unlocks as she gradually strengthens her memories help make her stealth-and-ambush playstyle even more powerful and flexible.

One such trait, “Silent Steps,” gained through her unique memories, lets her move without spending TP when she enters stealth while no characters are adjacent. Since Hide consumes TP but has no cooldown, using Silent Steps well means she can slip into stealth multiple times in a single turn—taking down enemies one after another.

To make her Ambushes even deadlier, Mienne’s core memory traits also give various bonuses to her surprise attacks. “Decisive Action” adds 10% extra damage per 1 point of her current Will when she lands a successful ambush. So, if her Will is well-managed, that can mean a whopping 40% damage boost.

“Ongoing Mission” gives her a 50% chance to recover WP after killing an enemy with an ambush.

All together, these traits let Mienne efficiently take out enemies with each Ambush, slip back into Stealth, and then target the next victim—performing a kind of “chain assassination.”



Today’s spotlight Survivor, Shadow Sister Mienne, is a high-risk, high-reward character who demands careful and strategic play. When used well, she can deal devastating damage to enemies, making her a great choice for skilled players!

We’ll be back next week with more character rework news.
