While Cherna isn't a witch that players will normally have any trouble facing in modes such as Arena, she does present a real challenge when fought in modes such as the main story. There, her inflated stats, Fainted and Bleed debuffs, and passive life steal, can easily overwhelm the unprepared.

Cherna Skill Analysis

Skill Skill Effect
Memento Mori - Portrait Icon

Level 1 (Unlocks by level 41)
Increases Cherna's HP Drain by 20% (cannot be dispelled).
Level 2 (Unlocks by level 101)
The amount her HP Drain increases by becomes 30%.

Cherna's unassuming passive is perhaps the most annoying part about facing her in PvE. Due to her massive, inflated bulk, Cherna can easily recover the HP she has lost while most of your team bumbles around with their random-targeting skills. Note that this HP Drain effect applies to all direct damage, which includes her basic attacks. That means she can heal on practically every turn.

Fortunately, there are a variety of methods to stymie or offset her recovery; all of which are available for players even during the early levels. One such method is to simply stop her from dealing damage through action-hindering debuffs. Offsetting her healing through damage-over-time effects such as Poison or Bleed can work, too.

Skill Skill Effect

Level 1 (Unlocks by level 11)
Cherna deals 1 magical attack equal to 360% of her ATK to 1 random enemy. Also has a 50% chance to inflict [Fainted]and[Bleed]on the target for 1 turn. Each turn, at the start of the action phase, [Bleed]deals damage equal to 10% of Cherna’s ATK.
Level 2 (Unlocks by level 21)
The targets of this skill become 2 random enemies.
Level 3 (Unlocks by level 81)
The chance to inflict[Fainted]and[Bleed]becomes 70%.
Level 4 (Unlocks by level 141)
The magical attack’s damage becomes equal to 390% of her ATK.

Although Cherna's overall damage isn't high by any means, the resulting bulk from her indiscriminate life steal and supplemental damage from Bleed can slowly stack up and cause large problems late into the match.

This is easily addressed by using witches that can purge debuffs such as Sivi.

Witches to Beat Cherna

Cherna Hard Counters

MementoMori - Cordie IconCordie

Fast, strong, completely immune to debuffs, and can shred Cherna's inflated defenses if she possesses her Exclusive Weapon; Cordie is an extremely reliable counter to Cherna whenever you encounter her in PvE.

MementoMori - Apostle Rosalie IconApostle Rosalie

Apostle Rosalie is a free and powerful counter against witches with debuffs on their kits, allowing the former to quickly stack their passive and clean up the field with her allies.

MementoMori - Lunalynn IconLunalynn MementoMori - Stella IconStella MementoMori - Claudia IconClaudia

Witches that can reliably disable Cherna's movements are very effective in stopping the latter from consistently topping their lost health up via her attacks.

At large enough level gaps, players will have to prepare for the longer fight against Cherna teams in PvE. For that reason, fielding Fenrir and Mertillier, who can repeatedly and consistently reduce your attackers' skill cooldowns, will allow players to overwhelm Cherna's annoying HP Drain.

By taking advantage of Cherna's weakness to Emerald soul witches, a team comprised of Emerald witches that collectively activates their Soul Bonus can make quick work of teams where Cherna is the only offensive threat.

Witches Not To Use Against Cherna

MementoMori - Mimi IconMimi MementoMori - Rean IconRean

Due to their requirement to pick up kills to extend their chain combo, using these types of witches on the premise that they'll be able to pick up stray KO's is a volatile strategy at best.

MementoMori - Amour IconAmour MementoMori - Amleth IconAmleth

Insurance Policy archetype teams that rely on late-game punishment might find that, by the time the match comes to that point, the situation may have already developed past the point where they can reliably turn the tables.

MementoMori - A.A. IconA.A. MementoMori - Belle IconBelle

Witches that rely even somewhat on their basic attacks might find it difficult to offset the combined effects of Cherna's skills.

Tips for Beating Cherna

Stack on PM Def Break

Cherna is only troublesome in PvE matches with a large stat discrepancy between her party and that of the player. Hence, stacking PM Def Break through runes and augmenting the dark element on the attacker's chest armor is a very reliable way to increase their damage.

Go On The Offensive

Due to how Cherna can simply heal back the HP she has lost throughout the game, only very few attrition-based teams that don't rely on Fia can emerge victorious, especially considering the inflated stats of PvE enemies. On the other hand, pushing through with brute force works quite well, as long as the player has enough stats and the strategy to compensate.

Use Crit Runes And Buffs

PvE enemies do not use runes. Hence, their Crit RES stats are always at their base values, which makes them all vulnerable to critical hits. Witches like Florence and Merlyn can take full advantage of this, quickly allowing players to overwhelm Cherna's healing with high-power attacks.
