Best Team Compositions
Magna synergizes perfectly with Maribell's core mechanics. Since both characters thrive on accumulating shields and counterattack stacks, they naturally complement each other's playstyle. Magna can leverage the defensive resources Maribell generates while contributing his own damage output, creating a cohesive defensive-offensive duo.
Mika serves as the ideal support for this pairing. She provides essential healing to maintain team health, generates additional action points to help Maribell overcome her AP consumption issues (especially in single-boss fights), and contributes extra shielding that amplifies Maribell's shield-scaling capabilities. This makes Mika's utility perfectly aligned with what Maribell needs to function optimally.
Alternative Team Members
| Character | Explanation |
 Mei Lin | Her primary value comes from providing offensive buffs that enhance Maribell's damage output. Since both characters share the Passion attribute, Mei Lin can take advantage of attribute synergy to amplify Maribell's effectiveness |
 Selena | Selena can fill the sub-DPS slot if neither Magna nor Mei Lin are accessible. Her contribution is more limited, she can inflict Passion weakness on enemies, which helps Maribell deal increased damage. |

Playstyle Tips and Strategy/How to Play
Maribell's gameplay revolves around two main strategies that you can adapt based on the situation:
Shield-Focused Approach: Build up shields first, then unleash Shelter Strike for maximum impact. Pair her with teammates like Mika (who provides strong shields through Blessing of Waves) or Magna (who offers continuous shielding each turn). If available, Amir can boost your shield generation further through Resolve buffs, amplifying how much protection Maribell creates.
Counterattack Strategy: Stack counterattack charges throughout the battle, this works best once you've unlocked her Potential 3-1, which lets even her basic cards generate counterattacks. Once you've accumulated enough stacks, cards like Maribell Shelter MK.II will deal significant damage. The Oh... I see card also converts your counterattack stacks into shields, offering both offense and defense.
General Playstyle
Maribell is pretty simple to use. Your main job is generating shields to keep the team safe through cards like Shelter Defense or attacking cards that also provide protection (Maribell MK.II). Her counterattacks add consistent chip damage over time, while not her main purpose, this passive damage helps wear down enemies or finish off weakened targets before your main damage dealer's next turn.
