Mastering Laios and Marcille in Arknights

by Jason Apr 25,2025

Arknights' collaboration with Delicious in Dungeon brings exciting new characters to the game: Laios and Marcille. Understanding their skills, playstyles, and deployment strategies can significantly enhance your gameplay. Both characters are available through the Crossover Limited Headhunting banner, requiring players to navigate the gacha system to unlock them. Once obtained, maximizing their potential is key, which is why we've put together this guide.

Laios: The Curious and Calculated Frontliner

Laios is a 5-star melee unit classified as a Dreadnought Guard, known for his strong, single-target offense. What sets him apart is his ability to reward players who pay close attention to enemy types and leverage repeated spawns. He's not a unit you can simply deploy and expect immediate success; rather, he's tailored for players who strategize and understand his unique mechanics.

Marcille: The Versatile Mage

Marcille, at Elite 2, unlocks the talent Reliable Companion, which grants her 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, significantly enhancing both offensive and defensive capabilities.

Skills and Combat Use

Marcille's three skills offer varied utility and damage profiles, all centered around mana management and timing:

  • A Top Student’s Abilities: A burst skill that enhances Marcille’s attack with mana. If no enemies are nearby, it heals allies instead, making it ideal for mixed-role usage.
  • Summon Familiar: Creates a companion that boosts her basic attacks and adds slow effects. Reactivating enhances the familiar, increasing range and adding a stun effect, perfect for crowd control and stalling tactics.
  • Explosion Magic: A high-mana skill that, after chanting, causes a massive AoE explosion with a stun effect. Additional chanting and mana investment turn it into a multi-hit attack, clearing groups of enemies swiftly, ideal for high-pressure stages.

Marcille's gameplay revolves around managing her uptime effectively. Deploy her during crucial wave moments, execute one or two skills, and then retreat to rebuild mana. This cycle rewards precise timing and strategic planning, especially when using SP-focused supports or delay tactics.

Building and Synergy

Marcille truly shines at Elite 2. Her second talent not only provides more starting mana but also significantly buffs your team if running a crossover-themed squad. For skill prioritization, Summon Familiar offers flexibility and utility across various stages, while Explosion Magic excels in scenarios requiring massive burst damage.

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 protect her during chants or indirectly boost her SP. She pairs excellently with Laios and other Laios’s Party members to leverage the team buff, but also fits into caster-focused compositions needing both damage and control.

Conclusion

Laios and Marcille introduce a unique flavor to Arknights, offering rewarding and quirky gameplay. Laios demands precision and tactical placement, while Marcille challenges players to manage her presence and mana for explosive results. Together, they provide a versatile core adaptable to both single-target and AoE challenges.

For those looking to explore new team builds, particularly centered around the Laios’s Party tag, both units offer strong synergy potential. To ensure the smoothest gameplay experience, especially during intense missions, consider playing Arknights on PC with BlueStacks for better controls, larger visuals, and uninterrupted play.
