Arknights’ collaboration with Delicious in Dungeon brings two unique operators, Laios and Marcille, to the popular strategy gacha game. Mastering their skills, playstyles, and optimal deployment strategies can greatly improve your overall performance.
Both operators are available through a special Crossover Limited Headhunting banner, meaning most players will rely on the gacha system to obtain them. Once you successfully recruit either unit, you’ll naturally want to maximize their potential—this guide will help you do just that.
Let’s get started!
Laios: The Tactical and Inquisitive Frontline Guard
Laios is a 5-Star Dreadnought Guard, a class known for powerful single-target assaults. What truly sets him apart is how his abilities reward players who study enemy types and capitalize on recurring spawns. He’s not an operator you can place thoughtlessly and expect top-tier results. Instead, he thrives under players who strategize in advance and adapt to his unique mechanics.
At Elite 2, she unlocks Reliable Companion, granting 25 initial Mana and a robust squad-wide buff when four or more Laios’s Party members are deployed. This talent boosts ASPD and DEF for the entire group, enhancing offensive output and survivability simultaneously.
Skills and Combat Strategies
Each of Marcille’s three skills serves a distinct role, balancing mana consumption and timing for maximum effect.
A Top Student’s Abilities: A burst skill that consumes mana to amplify Marcille’s attack power. When no enemies are in range, she switches to healing allies—ideal for hybrid offensive and supportive roles.Summon Familiar: Conjures a small familiar that strengthens her basic attacks and inflicts slow. Reactivating the skill empowers the familiar, extending Marcille’s attack range and adding a stun to each strike. Excellent for controlling enemy movement and stalling strategies.Explosion Magic: A high-impact area spell. After channeling, it unleashes a massive AoE blast that stuns targets. If Marcille continues channeling with additional mana, the skill transforms into a multi-hit barrage, swiftly eliminating clustered enemies. Best reserved for overwhelming waves.
Marcille’s playstyle emphasizes active Mana management. Deploy her during critical enemy waves, trigger one or two skills, then retreat her to rebuild Mana reserves. This rhythmic approach complements operators with SP-based abilities or delay tactics, rewarding foresight and timing.
Build Recommendations and Synergy
Marcille reaches her full potential at Elite 2. Her second talent not only boosts starting Mana but also provides powerful team-wide bonuses when running a crossover-themed squad. Regarding skill progression, Summon Familiar offers the most versatility across various stages, while Explosion Magic is preferred when massive burst damage is essential.
Recommended Development Path:
Promotion Priority: Elite 2 for improved Mana scaling and team synergySkill Upgrade Focus: Summon Familiar for utility; Explosion Magic for burst damageRecommended Potentials: Increased ATK and reduced redeployment time
For team synergy, Marcille excels alongside operators who protect her during skill channels or indirectly supply SP. She pairs effectively with Laios and other Laios’s Party members to activate her squad buff, and fits smoothly into caster-heavy lineups requiring both damage and control.
Laios and Marcille offer a fresh, engaging playstyle to Arknights, blending strategic depth with unique mechanics. Laios encourages precise placement and tactical foresight, while Marcille challenges players to manage her Mana for explosive results. Together, they create a versatile core capable of handling both single-target and area challenges.
If you're experimenting with team compositions—especially those revolving around the Laios’s Party tag—these operators deliver excellent synergy. And for the most seamless experience during demanding missions, consider playing Arknights on PC with BlueStacks.
