The most awaited limited character, Adelheid, has finally arrived in Chaos Zero Nightmare with a unique Vanguard playstyle focused on Blessing mechanics, powerful shielding, healing support, and fast deck cycling. Instead of relying purely on raw damage, Adelheid controls the flow of battle by protecting allies, enabling stronger combos, and supporting the entire team through consistent sustain and defensive utility.

In this Chaos Zero Nightmare Adelheid build guide, we’ll cover her best builds, cards, teams, Memory Fragments, and pull advice so you can fully maximize her potential in every type of content.

 

Building limited characters in Chaos Zero Nightmare often requires heavy resource farming, rerolling, and testing multiple setups before finding the best combination. With OSLink’s multi-instance manager, you can manage multiple accounts more efficiently while also experimenting with different Adelheid builds, team comps, and Blessing setups across several sessions at the same time, making progression and optimization much easier.

Adelheid Overview 

Attribute: Void

Class: Vanguard

Role: Sustain and Hybrid Carry

Adelheid is a versatile Vanguard support character who excels at team-wide shielding, card draw, and enabling consistent combos while also dealing hybrid damage through her special Blessing system. Because of this, she works as a main sustain unit for most teams by focusing on setting up Blessings, providing protection support, and dealing solid personal damage.

Core Mechanics

The core mechanic of Adelheid’s entire kit heavily relies on creating a special Blessing tag for the cards. Here is how her mechanic works:

 

• Adelheid applies Blessing to ally cards, including her own, mainly through Epiphany cards and upgrade cards.

• When a Blessed card moves from hand to the graveyard by playing, discarding, or other effects, and your team’s shield is below 30% HP, the team gains a fixed shield equal to 60%.

• This shield is capped at 30% of the team’s max HP, keeping it balanced while still providing reliable sustain.

• She also has extra defensive support like Damage Reduction effects and Shield Retention effects, which can reach up to 75% with Mythic or upgrade cards.

Because of these mechanics, Adelheid becomes stronger in decks that cycle cards quickly. The more Blessed cards you play or discard, the more shields your team gains. For this reason, she works especially well with fast-cycling characters.

Adelheid Ego Skill: Happy Ending 

Adelheid’s Ego Skill, Happy Ending, is a 6 EP skill that:

• Grants 300% Shield

• Heals based on your current shield amount

• Healing is capped at 30% of max HP

 

Her Ego Skill is a powerful defensive ultimate, but it costs a lot of EP. It shines when you already have shields built up through Blessing decks. This skill also allows Adelheid to support the team without needing a dedicated healer, especially during longer battles.

Adelheid Memory Fragment Setup

Adelheid is a strong sustain Vanguard character, so her best build should focus on shields, defense, and survivability.

4× Starlight and Dreams Set

• Also boosts her damage for extra support in battles.

Stat Priorities for Adelheid

Adelheid can be built in two different ways depending on the path you choose: Teddy Path or Doggie Path.

Support / Tank Build (Teddy Path)

The Teddy Path focuses on strong shields and damage reduction. So, focus on these stats first:

• DEF – Main priority to increase shield strength.

• HP – Helps raise the 30% HP threshold for Blessing activations and improves survivability.

• Speed – Allows faster card cycling, more Blessing activations, and more shield generation.

Damage Build (Doggie Path) 

The Doggie Path focuses on DEF-based damage attacks. So, give priority for these stats:

• DEF – Main priority because Doggie’s damage scales from DEF.

• Crit Rate – Important because Adelheid has a low base Crit Rate.

• Crit Damage – Increases overall damage output after improving Crit Rate.

Adelheid Team Compositions

Adelheid works as the main sustain vanguard in most teams, so her team compositions should focus on Blessing application and discard support to maximize shielding while enabling high-damage carries. With these mechanics, you can use the following best Adelheid team comps for your battles:

Adelheid + Heidemarie + Nia

This is the best-performing team for Adelheid, offering a stable and consistent discard-focused composition.

• Adelheid gives shields using Blessing and Doggy/Teddy summons.

• Heidemarie is the main DPS and gains more power from Adelheid’s discard effects.

• Nia helps with discarding cards and improving card cycling.

Adelheid + Diana + Mika

An aggressive discard and multi-hit composition that focuses on high damage output while maintaining good survivability.

• Adelheid protects the team with shields and Blessing support.

• Diana works as the main damage dealer and benefits from Adelheid’s damage buffs and Blessing effects.

• Mika gives extra shields and damage buffs for safer attacking.

Adelheid + Rin + Cassius

This Adelheid team is a stable and consistent sustain-focused composition, best for general content.

• Adelheid provides shields and card draw support.

• Rin reuses blessed cards to trigger more shield effects.

• Cassius increases team damage with Morale and attack buffs.

Pulling Advice for Adelheid 

Adelheid is a limited seasonal character, and her banner is currently available as part of Season 3 Phase 2, which started on May 27. So, is it worth pulling Adelheid?

 

• Yes, if you need strong shielding and sustain for harder content. She is considered a top-tier shielder with strong defensive gameplay.

• She is also a great choice for both new and experienced players who want a strong character for difficult battles, offering reliable sustain along with some damage support effects.
