New Re:Zero Units & Acquisition Guide
Update 20 brings the beloved Re:Zero universe to Anime Guardians with five powerful new units spanning multiple rarity tiers. Each character offers unique abilities and strategic value for different team compositions.
Contents
Satella (Witch of Envy) – Guardian Rarity
Flagship Unit: Satella stands as the most powerful addition in Update 20, featuring Guardian rarity with devastating area-of-effect (AoE) damage and crowd-control abilities. Her kit perfectly embodies the Witch of Envy’s terrifying power, making her essential for both wave clearing and boss encounters.
Acquisition Method: Available through the limited-time Re:Zero Part 1 event banner with increased summon rates during the first two weeks of the update.
Echidna (Witch of Greed) – Secret Rarity
Strategic Support: Echidna brings Secret rarity utility focused on knowledge manipulation and resource generation. Her abilities likely include tactical advantages such as enemy debuff amplification, team buff enhancement, and strategic resource management.
Acquisition Method: Obtainable through special event summons and event shop currency exchange.
Subaru Variants – Exclusive Rarity
Update 20 introduces three distinct Exclusive rarity versions of Subaru Natsuki, each representing different aspects of his character development:
Subaru (Lust) – Exclusive
Aggressive Damage Dealer: This variant focuses on high-damage output with aggressive positioning mechanics. Players report him as a superior alternative to Robin-type units, excelling in rapid elimination of priority targets.
Subaru (Sloth) – Exclusive
Control Specialist: Embodying the Sin of Sloth, this variant specializes in crowd control with abilities that slow, stun, and apply debuffs to enemies. Perfect for managing large waves and controlling battlefield positioning.
Subaru (Envy) – Exclusive
Reflective Warrior: Themed around envy, this Subaru variant features abilities that steal enemy buffs, reflect damage, and turn opponent strengths against them. Excellent for countering buff-heavy enemy compositions.
Acquisition Method: All three Subaru variants are available through the Re:Zero event banner and can be purchased with event currency from the Forbidden Forest stage.
Forbidden Forest Worldline: Complete Strategy Guide
The Forbidden Forest serves as Update 20’s centerpiece content, offering a challenging 30-wave Worldline stage with unique mechanics and valuable rewards. This end-game content requires strategic planning and specific team compositions to conquer effectively.
Shield Mechanics Breakdown
The Forbidden Forest introduces three distinct shield types, each requiring specific strategies to overcome:
Green Shield
Mechanic: When destroyed, this shield regenerates a Pink Shield on the target enemy.
Strategy: Prioritize breaking Green Shields last in multi-shield scenarios, as they create additional defensive layers. Focus on single-target damage dealers to prevent shield regeneration cascades.
Pink Shield
Mechanic: Standard protective barrier with no special interactions.
Strategy: Use focused fire from your highest damage units to break through efficiently. Pink Shields serve as the baseline defensive layer in most encounters.
Red Shield
Mechanic: Completely blocks all Active Skill damage.
Strategy: This is the most challenging shield type and requires fundamental changes to your approach:
- Rely exclusively on basic attacks and passive abilities
- Position units with strong auto-attack capabilities
- Utilize units with passive damage-over-time effects
- Avoid using units dependent on active skills for damage output
Recommended Team Composition
Primary Damage Dealers:
- Units with high basic attack damage
- Passive damage-over-time specialists
- Multi-hit auto-attack units
Support Units:
- Buff enhancers for basic attack damage
- Healing units to sustain through prolonged battles
- Crowd control specialists for wave management
Drop Rates & Farming Strategy
The Forbidden Forest offers the best farming opportunities for Update 20 content, with these key drop rates:
| Item | Drop Rate | Purpose |
|---|---|---|
| Mutant Grapple Fists | 3% | Evolution material |
| Umbral Shroud Robe | 3% | Evolution material |
| Voidborne Attire | 3% | Evolution material |
| Stella Arcane Crest | 3% | Evolution material |
| Abyss Tainted Heart | 3% | Evolution material |
| Astral Chain-Lace | 3% | Evolution material |
| Limit Breaker | 0.1% | Unit progression |
Farming Strategy: Due to the extremely low 0.1% drop rate for Limit Breaker items, consistent daily clears of the Forbidden Forest are essential. Consider forming dedicated farming groups and using macro strategies (where permitted) to maximize efficiency.
Limit Breaker System: Ultimate Progression
The Limit Breaker system represents the most significant progression addition in Update 20, allowing players to break through previous level caps and significantly boost unit power.
How Limit Breaking Works

Benefits of Limit Breaking
- Increased Level Cap: Units can progress beyond previous maximum levels
- Enhanced Base Stats: Significant boosts to all primary attributes

Strategic Considerations
Priority Units for Limit Breaking:
- Satella (Witch of Envy) – Your strongest Guardian unit

Resource Management: Given the extreme rarity of Limit Breaker items, carefully consider which units will provide the most value for your specific playstyle and team composition.

Pro Tips & Advanced Strategies
Forbidden Forest Optimization
Wave Management: The 30-wave structure requires resource management throughout the run. Save your most powerful abilities for waves 20-30, where enemy difficulty spikes significantly.
Shield Priority Order: When facing multiple shield types, follow this priority:
- Break Pink Shields first (standard, no penalties)
- Target Green Shields second (but be prepared for Pink regeneration)
- Save Red Shields for last (require basic attack focus)
Unit Positioning: Place units with strong basic attacks at the front to handle Red Shields, while positioning active skill-dependent units further back to focus on Pink and Green Shields.
Limit Breaker Maximization
Efficient Farming: Create a dedicated farming schedule for Forbidden Forest runs. The 0.1% drop rate means you’ll need approximately 1,000 runs on average to obtain one Limit Breaker.
Unit Selection Strategy: Prioritize Limit Breaking units that:
- Already have optimal traits
- Fit your primary team composition
- Have significant growth potential at higher levels
- Are essential for your preferred game modes
Artifact Synergy Combinations
Offensive Setups: Combine Eclipseborn Fang with Plaguebloom Scepter for maximum damage output, especially effective with DoT-focused team compositions.
Defensive Builds: Pair Abyssal Frost Aegis with Soulforged Warden for nearly unkillable tank units, perfect for solo progression and challenging content.
Support Enhancement: Arcanum Sage Wand works best with units that have multiple active abilities, maximizing cooldown reduction and ability effectiveness.
