"Expert Tips for Dominating with Laios and Marcille in Arknights"

Author : Hannah Mar 29,2025

Arknights’ collaboration with Delicious in Dungeon introduces two distinctive operators to the popular strategy gacha game: Laios and Marcille. Understanding their skill sets, playstyles, and effective deployment strategies can significantly enhance your gameplay experience.

Both of these characters are obtained from their corresponding Crossover Limited Headhunting banner, which means most players will need to wait out the gacha system before they can actually attempt to unlock them. Once you do obtain one of these units, you’ll want to maximize their potential, which is why we’ve created this guide.

Let's dive in!

Laios: The Curious and Calculated Frontliner

Laios is a 5-star melee unit classified under the Dreadnought Guard branch, known for strong, single-target offense. What sets him apart in The Doctor’s roster is his kit, which rewards players who pay close attention to enemy types and exploit repeated spawns. He isn’t a unit you can simply deploy anywhere and expect stellar results. Instead, he's tailored for players who strategize and adapt to his unique abilities.

At Elite 2, Laios unlocks Reliable Companion, granting him 25 initial mana and a powerful team-wide buff when your squad includes four or more Laios’s Party members. This talent boosts ASPD and DEF for the entire group, enhancing both their offensive and defensive capabilities.

Marcille: The Mana-Managing Mage

Marcille, a 5-star caster, introduces a unique gameplay loop centered around mana management and strategic deployment. Her three skills offer varied utility and damage profiles, each tailored to different combat scenarios.

Skills and Combat Use

  • A Top Student’s Abilities: This burst skill enhances Marcille’s attack using mana. If no enemies are nearby, she heals allies instead, making it versatile for mixed-role usage.
  • Summon Familiar: Creates a companion that boosts her basic attacks and adds slow effects. Activating it again enhances the familiar, increasing her range and adding a stun to each hit. Ideal for crowd control and stalling tactics.
  • Explosion Magic: A high-mana skill that, after chanting, unleashes a massive AoE explosion with a stun effect. Continued chanting and additional mana expenditure transform it into a multi-hit attack, clearing groups of enemies swiftly. Perfect for high-pressure stages.

Marcille’s gameplay revolves around managing her uptime effectively. Deploy her during critical wave moments, use a skill or two, and then retreat to rebuild mana. This cycle rewards good timing and planning, especially with SP-focused supports or delay tactics.

Building and Synergy

Marcille truly shines at Elite 2, where her second talent not only increases her starting mana but also provides significant team-wide buffs when running a crossover-themed squad. For skill prioritization, Summon Familiar offers flexibility and utility across various stages, while Explosion Magic is ideal for when you need a massive burst.

Recommended Development Path:

  • Promotion Priority: Elite 2 for mana scaling and support synergy.
  • Skill Upgrade Focus: Summon Familiar for utility; Explosion Magic for burst.
  • Best Potentials: ATK increase and redeployment time reduction.

Marcille synergizes well with operators who can protect her during chants or indirectly boost her SP. She pairs excellently with Laios and other Laios’s Party units to leverage the extra team buff, fitting seamlessly into caster-focused compositions needing both damage and control.

Conclusion

Laios and Marcille add a fresh and unique flavor to Arknights, offering gameplay that’s both rewarding and quirky. Laios challenges players with precision and tactical placement, while Marcille requires careful mana management for explosive results. Together, they form a versatile core capable of tackling both single-target and AoE challenges.

If you’re exploring new team builds, especially those centered around the Laios’s Party tag, both units offer strong synergy potential. For the smoothest gameplay experience, particularly during intense missions, consider playing Arknights on PC with BlueStacks. You'll benefit from better controls, larger visuals, and uninterrupted gameplay, ensuring every move counts.
