The exciting collaboration between *Arknights* and *Delicious in Dungeon* brings two unique operators, Laios and Marcille, to the forefront of the strategy gacha game, enriching the gameplay experience with their distinctive skill sets and playstyles. These characters are exclusive to their Crossover Limited Headhunting banner, meaning players will need to engage with the gacha system to unlock them. Once obtained, understanding how to maximize their potential becomes crucial for enhancing your team’s performance.

Laios: The Curious and Calculated Frontliner

Laios, a 5-star melee unit under the Dreadnought Guard branch, is renowned for his strong, single-target offense. What sets him apart is his ability to reward players who are attentive to enemy types and strategic with repeated spawns. Laios is not a plug-and-play unit; he demands thoughtful planning and tactical deployment to yield optimal results.

Skills and Combat Use

At Elite 2, Laios unlocks *Reliable Companion*, which provides him with 25 initial mana and a powerful team-wide buff when your squad includes four or more members of Laios’s Party. This talent significantly boosts both Attack Speed (ASPD) and Defense (DEF), enhancing the team’s offensive and defensive capabilities.

Marcille: The Strategic Mage

Marcille, another 5-star operator, brings a strategic depth to your team with her diverse skill set centered around mana management and timing. Each of her three skills offers unique utility and damage profiles, catering to different combat scenarios.

Skills and Combat Use

*A Top Student’s Abilities* is a burst skill that enhances Marcille’s attack using mana. In the absence of enemies, it switches to healing allies, making it versatile for mixed-role usage. *Summon Familiar* creates a companion that boosts her basic attacks with slow effects; reactivating it enhances the familiar, extending her range and adding a stun to each hit, perfect for crowd control. *Explosion Magic* is her ultimate skill, a high-mana ability that, after chanting, delivers a massive AoE explosion with a stun effect. Extended chanting and additional mana turn it into a multi-hit attack, ideal for clearing groups quickly.

Marcille’s effectiveness hinges on managing her deployment timing and mana. Deploy her during critical wave moments, utilize her skills, and retreat her to recharge mana. This cycle demands precise timing and strategic planning, especially when combined with SP-focused supports or delay tactics.

Building and Synergy

Reaching Elite 2 is key for Marcille, as it not only increases her starting mana but also activates significant team-wide buffs when paired with a crossover-themed squad. For skill development, prioritize *Summon Familiar* for its broad utility, while *Explosion Magic* excels in scenarios requiring a burst of damage.

Recommended Development Path:

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

Marcille synergizes well with operators that ensure her safety during chants or indirectly boost her SP. She pairs excellently with Laios and other Laios’s Party members to leverage the team buff, and she also complements caster-focused compositions needing both damage and control.

Together, Laios and Marcille inject a fresh and quirky dynamic into *Arknights*. Laios encourages precision and strategic placement, while Marcille challenges players to master mana and timing for explosive results. This duo forms a versatile core capable of tackling both single-target and AoE challenges.

For players eager to experiment with new team builds, especially those centered around the Laios’s Party tag, both operators offer strong synergy potential. To ensure the smoothest gameplay, particularly during intense missions, consider playing *Arknights* on a PC with BlueStacks. This setup provides enhanced control, larger visuals, and uninterrupted play, helping you make every move count.
