Arknights' exciting collaboration with Delicious in Dungeon brings two unique operators into the mix: Laios and Marcille. These characters can greatly enhance your strategic gameplay, and understanding their skills, playstyles, and deployment strategies is key to maximizing their potential. Both operators can be obtained through the Crossover Limited Headhunting banner, requiring a bit of luck and patience with the gacha system. Once you've managed to recruit them, let's dive into how you can make the most out of Laios and Marcille.
Laios: The Curious and Calculated Frontliner
Laios, a 5-star melee unit from the Dreadnought Guard branch, specializes in strong, single-target attacks. What sets him apart is his ability to capitalize on enemy types and repeated spawns, making him ideal for players who strategize their deployments meticulously. Laios thrives in scenarios where tactical planning is crucial, rather than being a straightforward drop-in fighter.

Marcille: The Versatile Mage
Marcille, on the other hand, is a versatile mage whose effectiveness hinges on mana management. At Elite 2, her talent, Reliable Companion, not only grants her 25 initial mana but also boosts her team's ASPD and DEF when four or more members of Laios’s Party are present. This synergy is vital for enhancing both offensive and defensive capabilities.
Skills and Combat Use
Marcille's three skills offer varied utility and damage options:
- A Top Student’s Abilities: A burst skill that enhances her attack or heals allies when no enemies are nearby, making it perfect for mixed-role scenarios.
- Summon Familiar: Generates a companion that boosts her basic attacks with slow effects. Re-activating this skill enhances the familiar, increasing her range and adding a stun effect, ideal for crowd control and stalling.
- Explosion Magic: A high-mana skill that, after chanting, delivers a massive AoE explosion with a stun. Further chanting and mana investment turn it into a multi-hit attack capable of clearing groups swiftly, perfect for high-pressure stages.
Marcille’s gameplay revolves around strategic timing, deploying her during critical moments, executing skills, and retreating to regain mana. This cycle rewards careful planning, especially with SP-focused supports or delay tactics.
Building and Synergy
Reaching Elite 2 is crucial for Marcille, enhancing her mana scaling and support synergy. Prioritizing Summon Familiar offers versatile utility across various stages, while Explosion Magic is the go-to for needing significant bursts.
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 members of Laios’s Party for additional team buffs and integrates smoothly into caster-focused compositions needing both damage and control.
Conclusion
Laios and Marcille introduce a dynamic duo to Arknights, blending precision and tactical depth with Marcille's explosive mana management. They offer strong synergy for teams, particularly those themed around Laios’s Party, providing flexibility to tackle both single-target and AoE challenges.
