If you want a hero that goes through any of the content easily, then go for the SS rank. These are the overpowered heroes that anyone can rely on the MementoMori tier list and they show no weakness. In of attacks, damage, defense and overall combat powers, these are your powerhouses.

The best heroes from the SS rank that we can recommend to you are:

Fenrir

Sorcerer (/Damage Dealer)	Runes: Prioritize MAG (Magic) and CRIT Rate to maximize damage and debuff‑cleanse reliability. Gear: Equip pieces with MAG DEF and Cooldown Reduction to enhance uptime. Skill Upgrades: Upgrade Icicle Shower for improved debuff removal and scaling damage.	Fenrir excels in PvE (Main Quest, Tower of Infinity) and PvP (Battle League). Ideal for teams needing offensive —pairs well with high‑damage dealers like Cordie or Florence.

Fenrir in the MementoMori tier list 2025 is consistently one of the best ers paired with high damage output. Her Snow Wolf’s Fangs deal 490% of her Attack as magical damage to a single target while reducing an adjacent ally’s skill cooldown by 1. On the other hand, her Icicle Shower delivers five random attacks (230% Attack each) and removes two debuffs from herself and an adjacent ally. This combination of damage, cooldown reduction, and debuff cleansing makes Fenrir one of the best versatile heroes for your gameplay.

Cordie (Summer Version)

 

Role	Specialty	Strategies
Sniper (Damage Dealer)	Runes: Focus on ATK, CRIT Rate, and CRIT DMG to amplify her burst potential. Gear: Use gear with HP and ATK to maintain her HP threshold for Fanning Shots. Skill Upgrades: Prioritize The Quick & the Dead for higher damage and buff triggers.	Cordie shines in PvE (Guild Raids, Cave of Space‑Time) and PvP. She’s best in teams with healers or tanks (e.g., Fortina, Olivia) to keep her HP above 50%. Her high damage and Defense Break make her a go‑to for players tackling tough bosses or competitive modes.

Cordie (Summer Version) is a top-tier Sniper lauded for her massive damage multipliers and snowballing potential. Her The Quick & the Dead unleashes five random attacks (570% Attack each), granting a 50% Attack buff for one turn if an enemy dies. Fanning Shots deals five random attacks (390% Attack each), doubling damage if her HP is 50% or higher. Her ive, All Eyes on Me, provides a permanent 40% Attack and Defense Break, making her a nightmare for enemies.

Olivia

Skill Upgrades: Upgrade Fortifying Blade for increased damage buffs and shield strength.	Olivia is better in PvE (Main Quest, Trials) and PvP (Legends League). She fits in teams with high‑damage Sorcerers or Snipers (e.g., Fenrir, Cordie) to increase their output while providing defensive utility.

Olivia from the MementoMori tier list is considered one of the best all-around ers, capable of dealing significant damage while securing team survivability. She can increase allies’ ATK based on her own, provide a sturdy shield to all allies, and briefly reduce enemy ATK. Her Fortifying Blade buffs damage for herself and slower allies, enhancing team synergy. Her ability to boost MAX HP and deal frontline damage makes her a versatile pick.

Florence

Role	Specialty	Strategies
Warrior (Damage Dealer)	Runes: Focus on ATK, CRIT Rate, and SPD to maximize her damage and turn frequency. Gear: Use gear with ATK and CRIT DMG to enhance her burst potential. Skill Upgrades: Prioritize her primary damage skills (e.g., Les Rose Bleue) for increased scaling and DEF reduction on crits.	Florence is ideal for PvE (Guild Raids, Tower of Infinity) and PvP. She thrives in teams with ATK buffers (e.g., Olivia, Merlyn) and debuffers (e.g., Moddey).

She excels in dealing with massive physical damage and is often paired with s like Merlyn for devastating alpha strikes.

Sivi

Role	Specialty	Strategies
Warrior (/Tank)	Runes: Prioritize DEF, HP, and ATK to balance her tanking and damage buffs. Gear: Equip gear with Survivability (HP/DEF) and some ATK to her buffing role. Skill Upgrades: Upgrade Fortifying Blade for higher damage buffs and defensive utility.	Sivi is best in PvE (Main Quest, Cave of Space‑Time), particularly in teams with slower, high‑damage units (e.g., Amleth, Elfriede). She's less suited for fast‑paced PvP but excels in prolonged battles where her buffs and healing shine.

Sivi is a newer character with strong potential, though her ranking is still stabilizing due to her recent release. Her Fortifying Blade grants up to 75% damage buffs (with investment) to herself and her two slowest allies, paired with increased DEF, healing, and debuff cleansing for the slowest ally. This makes her a slow, steady grinder who enhances team durability and damage over time.

Lunalynn’s ability to control enemies with Silence and weaken them with Poison makes her a strong pick for both PvE and PvP, particularly against teams reliant on skill-based burst damage.

B Rank Heroes – The Decent Performance

B-rank heroes are not the strongest in the game but will be ideal for the MementoMori beginner. They do the best in the early gameplay, so they will not be so ideal for the end game.

The best hero that we can recommend from this rank in the MementoMori tier list  is:

• Loki: Loki as a damage dealer valued for her single-target damage and crowd control, particularly in early to mid-game content. She’s best in teams with healers like Fortina or Yuni to keep her HP above 50%, paired with DPS like Cordie for synergy in targeting weakened enemies. Her Silence is particularly effective against skill-heavy bosses or PvP teams, making her a favorite for players tackling mid-game content or building accessible rosters.

C Rank Heroes – Lowest Performers

C-rank heroes in the MementoMori tier list are not so ideal because of their weak stats. In order to take the full potential of them for the battles, you will have to upgrade them more.

This is the best hero that we can recommend to you from the C rank of this tier list.

• Rosalie: Rosalie is a er and will be best at healing and minor damage capabilities. As a free character obtained after clearing Quest 1-2, her accessibility makes her a favorite among new players. Her healing is less effective in PvP or late-game content due to lower scaling, but her accessibility and utility make her a popular choice for new players building their first teams.
