Necrofica Build Guide: Building the Executioner for Damage, Not Defense

A lot of Necrofica advice says to “build her tanky so she survives long enough to execute.” Top players’ data points the other way. Her most common build is Bloodlust + Revitalize Insignia, which is a damage-and-tempo setup, and Dodge barely shows up in her trait data. The reason is that her kit already provides most of the defense she needs.

What her skill actually does

Hundred-Bone Howl (7s cooldown) deals 2625% ATK to all nearby enemy heroes and puts all friendly heroes into Sin Devouring for 5s.

• Sin Devouring: each time a friendly hero in this state takes damage, it restores 8% energy and gives Necrofica 1 stack of Soul Punishment.
• Soul Punishment: each stack gives Necrofica Secure Armor worth 5% of her Max HP for 3s. At 10 stacks she instantly executes the nearest enemy hero and Frightens nearby enemies for 3s, ignoring condition immunity. She heals 30% of Max HP during the execution.
• If the executed hero was below 45% HP, it can’t be revived.
• The execution ignores damage reflection, invulnerability and DMG-to-HP Conversion. Skill immunity can block it.

Her passives are a large part of her value:

1. Every 8s, reduces all enemy heroes’ healing received by 90% for 3s.
2. Each time she’s attacked, recovers 10% energy and 5% of Max HP.
3. Sturdy: can’t take more than 15% of her HP per hit.
4. Reduces damage received by 70%.
5. All her damage ignores damage limits and Sturdy.
6. Immune to Inhibit, Silence, DMG-to-HP Conversion and all conditions.

Her stacks come from your whole team taking damage, not from her own hits. The more the enemy attacks your team during Sin Devouring, the faster she executes.

The top-player build

Slot	Top pick	Pick rate	Runner-up
Talent	Bloodlust	39.1%	Revive (17.0%)
Insignia	Revitalize Insignia	52.9%	Survival Insignia (15.4%)
Square insignia	Winged Rebirth Insignia	57.6%	Fairy Circle Insignia (15.9%)
Enchantment	Holy Conviction	77.8%	Unbridled Fury (5.9%)
Trait	Accuracy	87.6%	HP (5.8%)
Pet skill	Aquatic Heart (M)	21.8%	Grave Assault (M) (6.1%)

Pick rates are from IGG’s official hero data for top players.

Talent: Bloodlust (39.1%)

Bloodlust gives +100% ATK and, once an enemy hero drops below 50% HP, +300% ATK for 3s that ignores invulnerability. Her skill is a 2625% ATK hit to every nearby enemy, and it ignores damage limits and Sturdy. Bloodlust makes that hit much larger and makes it easier to push targets below 45% HP, the point where her executions stop them from reviving. Revive (17.0%) is the safer second choice.

Insignia: Revitalize (52.9%)

Revitalize gives full energy at the start of the fight and +120% ATK for 10s. The first cast of Hundred-Bone Howl starts the whole Sin Devouring loop, so getting it out immediately is worth more than extra durability. Necrofica is one of the heaviest Revitalize Insignia users in the game.

Square insignia: Winged Rebirth (57.6%) or Fairy Circle (15.9%)

Winged Rebirth is the Epic default. Fairy Circle (+140% Max HP, +115% healing received, immunity to one fatal hit) is the second choice, and it works well with her 30%-of-Max-HP execution heal.

Enchantment: Holy Conviction (77.8%)

Necrofica has the highest Holy Conviction pick rate of any hero. Its 85% damage reduction stacks with her built-in 70%, and its +320% healing received multiplies both her on-hit 5% heal and her 30% execution heal.

Trait: Accuracy (87.6%)

Only 5.8% of top builds pick HP and 3.4% pick ATK. Dodge doesn’t appear in her top three at all. Her damage has to land to push targets under the 45% no-revive threshold, so Accuracy is the obvious choice.

Pet skill: Aquatic Heart (M) (21.8%)

When her hero lands a critical hit, mutant Marine Mermaid deals 1280% pet ATK to 3 random enemy heroes, and enemies that cast a skill in the next 5s lose HP equal to 30% of their skill damage. It also gives nearby friendly heroes +30% ATK SPD.

How her stats compare

Her raw stats are ordinary for an Epic: 410 ATK, 12,000 HP. She has the highest ATK growth per level (+25) of any Epic, though, and a fast 1,100 ms attack interval. Her real durability is in her passives, which don’t show up in the stat line.

Counters and caveats

• Skill immunity blocks the execution. It’s the one thing her execution text says it can’t get through.
• Her stacks depend on your team taking damage during the 5s Sin Devouring window. If the enemy isn’t attacking your team, the stacks come slowly.
• The no-revive clause only applies if the executed hero was below 45% HP. That’s why damage matters more for her than it first seems.

Heroes built the same way

Her build overlaps most with Cyclonica, Soulsnare Butterfly, Miracle Puppet and Bell Elk Maiden. AllClash’s 2026 tier list (updated May 2026) ranks her S+ for Arena.

• Talent: Bloodlust (Revive if you want safety).
• Insignia: Revitalize.
