NIKKE April 2026 Union Raid Guide: Best Teams & Tips

Event Schedule at a Glance

Critical scheduling note: Arcana's banner closes before Union Raid opens. If you're pulling for her shotgun synergy, that decision has to happen before April 9.

The Regroup feature (confirmed April 2026) allows mid-fight squad swaps and retries in both events without a full restart. This changes everything about how you handle failed burst rotations — use it instead of abandoning attempts.

April 2026 also confirmed Treasure upgrades for: Helm, Drake, Laplace, Tove, Miranda, and Sakura.

Moran: Playable Unit, Not a Boss

Most guides bury this: Moran is a unit you deploy, not a Union Raid boss. The April 10–16 bosses are Stormbringer and Modernia. Moran (SSR Tetra Electric AR Defender Burst I) is a team-building piece valued for her damage reduction and taunt.

Why She's Relevant

Skill 1: DEF increases 3.51% per 1% HP lost, capping near 350% DEF. The more damage she takes, the harder she is to kill. Her Burst Fair and Square (40s cooldown) switches to SMG, deals 14.7% final ATK ×10 over 10 seconds, applies 36.14% lifesteal, taunts all enemies for 10 seconds, and grants allies Damage Taken −35.14%. That last number is why she sees play.

Community consensus: tankier than Noise against single-target nukes in PvP and Special Interception. The trade-off is real though — she competes with Liter and Volume for the B1 slot. In sustained PvE, Liter's CDR value usually wins. If your team isn't dying, run Liter. If survivability is the bottleneck, Moran's taunt + DR package is genuinely irreplaceable.

Skill Investment Order

• S1 → Level 5 first (DEF scaling is her core tool)
• S2 → Level 5 second (HP and tankiness)
• Burst → Level 4 (minor boost, not worth prioritizing)

Harmony Cube: Vigor for raw tanking, Resilience for taunt uptime. Skip Bastion and ammo cubes — they don't interact with her kit.

Union Raid Boss Stats & What They Demand

• Stormbringer: 1.226B HP, 13.33K DEF (community-measured). Standard physical damage hits a wall here. True damage is the only reliable bypass.
• Modernia: 1.337B HP, requires Synchro Level 221+ to engage. More forgiving on DEF, but has an enrage phase (more on this below).

These aren't brute-force bosses. They require specific damage types and tight burst windows.

Best Team Compositions for Union Raid

Tier 1: Meta Team (Crown-Centered)

Liter (B1) → Crown (B2) → Rapi: Red Hood (B3) → Cinderella (B3) → Naga

Crown's B2 amplification stacks multiplicatively with Naga and Tia buffs — community testing confirms this is not additive. Cinderella's true damage bypasses Stormbringer's 13.33K DEF entirely. Without her, you're capped by the DEF wall. Position Crown leftmost for healer proc priority and to let her S2 pre-stack before the fight intensifies.

Tier 2: F2P Core (No Cinderella)

Liter (B1) → Crown (B2) → Rapi: Red Hood (B3) → Modernia (B3) → Naga

Performs excellently against Modernia, holds up reasonably against Stormbringer. You'll notice a damage ceiling on Stormbringer without true damage, but this team is your primary squad if Cinderella isn't built.

Tier 3: Moran-Integrated (Survivability-First)

Moran (B1) + Liter/Volume/Dorothy + B2 amplifier + 2× B3 DPS

Use this when your DPS units keep dying before dealing meaningful damage. Moran's 35.14% team DR during Burst creates a survivability floor. Community testing shows Scarlet, Guillotine, and Snow White as the best B3 options here. Again — if your team isn't dying, run Liter instead.

Tier 4: Second-Squad Enabler

Union Raid rewards roster depth. Your guild's total score depends on multiple teams contributing, not one optimized squad.

Common mistake: Saving Crown and Liter for every fight. Use RL-heavy compositions on Obelisk and Doctor, reserve your Crown/Liter core for Modernia and Stormbringer where the multiplicative amplification actually matters.

Burst Rotation Fundamentals

Every squad needs one of each tier: B1 buffer → B2 amplifier → B3 DPS. Missing any tier creates burst generation gaps that compound over a 3-minute fight. Non-negotiable.

Guild Strategy & Scoring

CP Deficit Formula

Community-derived: max(0, (Stage CP - Team CP)/Stage CP), with power law 1.039957 × deficit^0.478827 applying between 1–48% deficit. Practically: 25–35% deficit with green-bordered Nikkes (who perform one tier higher in that range when fully raised) is manageable. Red-bordered units need 10/10/10 skills to function at high deficit — don't bring under-invested red-borders expecting miracles.

Coordination Priorities

Assign your guild's strongest rosters to Modernia and Stormbringer. Mid-tier rosters handle Obelisk and Doctor with RL-heavy compositions. Casual guilds consistently waste score by letting everyone run the same boss — this creates overlap and burns attempts where diminishing returns kick in.

Use Regroup to recover from failed burst rotations rather than abandoning attempts. Especially valuable on Modernia where the enrage skip timing is tight.

The Modernia Enrage Skip (Most Guides Miss This)

Pause the game immediately before Modernia's timer expires to skip her enrage phase. Community-discovered, not officially documented, but consistently reproduced across multiple Union Raid rotations. The window is 1–2 seconds before the timer hits zero. Miss it and incoming damage spikes significantly.

Combined with Regroup, this creates a reliable recovery loop: failed burst rotation during the enrage window → Regroup → reset positioning → retry. This is the single biggest skill-expression opportunity in April 2026 Union Raid.

Anomaly Interception April 2026: Arcana & the Shotgun Meta

Arcana (SSR Elysion Fire SG Attacker Burst II) is a playable unit from the Fortune Mate banner — not an Anomaly Interception boss. Her kit buffs shotgun allies' ATK based on her attack count before Burst. Longer fights = more stacks = better performance. She's built for sustained Anomaly Interception encounters, not short burst windows.

Community tier: Burst II T2 for PvE in the current rotation.

Shotgun Meta Team Structure

• B1: Liter or Volume (CDR + ATK buff)
• B2: Arcana (shotgun ATK amplification)
• B3: Privaty UM or Tove Treasure (primary SG DPS)
• Support: Naga or Rapunzel
• Flex: Second SG DPS or additional buffer

Honest assessment: Arcana pays off only if you have Privaty UM or Tove Treasure invested. Without SG partners, her value drops significantly. She's a synergy unit, not a standalone carry.

Boss Rotation & Farm Priority

Anomaly Interception has 5 permanent bosses unlocked after clearing the 22-36 Boss. Stage 1 rewards exceed Interception EX Stage 9 — if you're still grinding EX stages, you're leaving rewards on the table.

Farm priority order (community consensus):

1. Kraken — Custom Modules (+50 shards/run, 161/day cap — April 2026 Phase 7 boost, officially confirmed)
2. Indivilia — Torso pieces
3. Ultra — Head pieces
4. Harvester — Leg pieces
5. Mirror Container — Arm pieces

Check the active modifier before locking in your team each day. If it buffs SG ATK or SG crit rate, Arcana's team jumps from T2 to effectively T1 for that encounter. The Regroup feature lets you adjust mid-attempt if your initial read was wrong.

Takina in April 2026

Takina Inoue (SSR from the Lycoris Recoil collab) launched February 12, 2026. Her banner ended March 12, 4:59 UTC+9 — she's not obtainable through standard banners in April. If you have her, she functions as a general AR Defender: competent, not meta-defining in the current rotation. She fits second-squad compositions targeting Obelisk or Doctor, but she's not optimal for Stormbringer or Modernia given the DEF-heavy meta.

There is no Takina Anomaly Interception boss in the April 2026 rotation. That framing conflates the unit with a boss encounter.

Pull Priority & Resource Management

Arcana sits outside this core list. Shotgun-specific investment that only pays off with Privaty UM or Tove Treasure already built.

Gem & Stamina Allocation

F2P players generate roughly 8,000–12,000 gems/month. Reserve 15,000–25,000 gems pre-banner if targeting a specific pull. Arcana's banner closes April 9 — hard deadline.

For stamina: prioritize Anomaly Interception during the Phase 7 Kraken boost. Three full daily attempts are mandatory — don't let them expire. Union Raid attempts are time-gated to April 10–16, so they don't compete with daily stamina the same way.

Boss Prioritization: Where to Spend Limited Attempts

If your roster can't reliably bypass Stormbringer's 13.33K DEF, redirect that squad to Obelisk or Doctor. You still contribute guild score, and you're not burning attempts into a damage ceiling.

Overload Gear Priority

Custom Modules from Kraken first (obvious during the April boost), then Indivilia Torso → Ultra Head → Harvester Leg → Mirror Arm. Treasure unlocks at SR Doll Phase 15; Bond Level 30 grants +2 duplicates. If you're close to either threshold, get there before farming specific pieces.

Helm Treasure note (community-tested): Outperforms Crown in campaign content at under 25% CP deficit at SSS investment. At high deficit, drops to SS tier while Crown stays consistent. For Union Raid — where you're fighting near your CP ceiling — Crown is still correct. But don't feel like you're playing suboptimally if you're using Helm Treasure in campaign between events.

Moran's PvP Niche

Most Union Raid guides ignore this entirely. Moran has a legitimate PvP role worth knowing about.

Community-tested PvP composition: Moran + Biscuit + Anis: Sparkling Summer + Maiden + Centi Summer

This specifically counters Anis SS, Scarlet: Black Shadow, and Red Hood — three of the most common PvP threats right now. Moran's taunt pulls aggro from your DPS units, Biscuit's invulnerability windows pair with Moran's −35.14% team DR during Burst, and the combination creates a survivability floor that burst-damage teams struggle to break in the time limit. If you're building Moran for Union Raid survivability, PvP utility comes free.

FAQ

What if I don't have Crown or Cinderella? Run Liter → Naga → Red Hood → Modernia + flex. You'll hit a damage ceiling on Stormbringer specifically, but Modernia is very clearable. Focus guild score contribution on Modernia, redirect a second squad to Obelisk/Doctor. Don't skip Union Raid — partial contribution still counts toward guild milestones.

Can I S-rank Anomaly Interception without Overload gear? Yes, depending on the boss and unit investment. Stage 1 is accessible without overload gear. The Phase 7 Kraken boost applies regardless of gear level — run your three daily attempts even with unoptimized equipment. You're farming shards to build overload gear, not requiring it to farm.

Is Arcana worth pulling before April 9? Only if you have Privaty UM or Tove Treasure invested. Without SG partners, she's a B2 unit with limited general-purpose value. If you're sitting on 15,000+ gems and have the SG roster to support her, solid pickup. Saving for Crown or Red Hood? Skip her.

How does Regroup change Union Raid strategy? It removes the one mistake = wasted attempt penalty. Be more aggressive with burst timing. Failed rotation, mistimed Modernia enrage skip, squad wipe — Regroup and retry instead of playing conservatively to avoid errors.

Which Anomaly Interception boss if I only have time for one per day? Kraken. Unambiguously. The +50 Custom Module Shards per run (161/day across three attempts) is the best gear progression available in April 2026. Custom Modules are the overload gear bottleneck — prioritize them while the boost is active.

How do I coordinate Union Raid in a casual guild? Assign two or three strongest rosters to Modernia and Stormbringer. Everyone else runs Obelisk and Doctor with RL-heavy compositions. Track assignments in Discord or a simple spreadsheet. Remind members to use Regroup rather than abandoning failed attempts.

The April 2026 window is tight. Arcana's banner closes April 9, Union Raid runs April 10–16, and the Kraken boost runs all month. If you need to top up gems before the window closes, Goddess of Victory NIKKE recharge discount coupon April 2026 is available at BitTopup with fast, secure delivery. Get your gem situation sorted before April 10 — you don't want to be making pull decisions under time pressure during Union Raid week.

Run both events. Use Regroup. Don't let Modernia enrage you.
