The physical attacks’ damage becomes equal to 460% of her ATK.

Memento Mori - Shining Blade Icon
Shining Blade
Level 1 (Unlocks by level 11)
Deals 1 physical attack equal to 350% of Rean's ATK to 4 random enemies. If a target is defeated by this skill, it deals 1 additional physical attack equal to 480% of her ATK to the enemy with the lowest remaining HP percentage. Each time a target is defeated by this skill, the number of additional physical attacks it deals increases by 1.
Level 2 (Unlocks by level 21)

Crimson Slash excels in sustained damage with its self-buffing mechanic, while Shining Blade offers explosive potential through chain reactions and self-healing.

However, both skills need to improve on random targeting, hindering consistency.

My Vow from That Day gives Rean a substantial shield at the start of the battle, offering a solid defense that enemies cannot remove. On the other hand, Feisty Determination boosts Rean's critical hit chance when her health is low, potentially turning the tides of a difficult battle.

While this skill relies on Rean being in a precarious situation, it offers a powerful offensive counter when activated. These skills create a balanced approach, combining defensive stability with offensive potential.

Witches to Beat Rean

Rean Hard Counters

MementoMori - Kaguya IconKaguya

While Kaguya doesn't have a direct counter to Rean's specific skills, her overall kit provides a strong foundation for countering her. By weakening Rean, protecting allies, and potentially punishing her attacks, Kaguya can be a formidable opponent against Rean.

MementoMori - Nina IconNina

Nina's kit is focused on dealing damage, dispelling buffs, inflicting debuffs, and increasing her survivability. Her skills are designed to disrupt enemies, protect herself, and deal consistent damage. Her ability to dispel buffs, crucial to countering Rean's ATK buff, makes her a valuable asset.

Combining Nina and Merlyn's debuffing capabilities, Soltina's critical hit reduction, Paladea's high damage output, and Cordie's control and damage, this team can effectively disrupt Rean's strategies. This team's skillset weakens Rean's abilities, deals massive damage, and controls the battlefield, making it a solid counter to her strengths.

Witches Not To Use Against Rean

MementoMori - Florence IconFlorence

Characters solely focused on high damage output might struggle if they cannot quickly eliminate Rean before she builds up her ATK buff.

MementoMori - Amour IconAmour

Characters with high defense but low damage output might find countering Rean's aggressive playstyle challenging.

Tips for Beating Rean

Focus Fire

Prioritize taking down Rean as quickly as possible. Concentrate on your party's attacks on her to prevent her from building up power.

Disrupt Her Buffs

If Rean relies on buffs to increase her power, try to dispel or negate these effects to weaken her. Use abilities that can Faint, Sleep, or Silence to interrupt Rean's actions if possible.
