Aniimo Rainbow Event: How to Choose and Train Limited Units

To get the highest combat value from the Aniimo Rainbow event, select a limited Rainbow creature that fills an immediate gap in your team's elemental coverage or role, then commit all your training materials to fully maxing out that single unit. Spreading experience items and stat-boosting fruits across multiple event units weakens your team's effectiveness in high-difficulty encounters.

Criteria for Selecting a Limited Rainbow Unit

Before spending event currency or redeeming exclusive unit claims, audit your existing squad to identify missing functions:

• Role Requirements: Identify whether your lineup requires a primary damage dealer, a defensive anchor, or a support buffer.
• Elemental Coverage: Choose an element type that complements your existing rotation and fills matchup weaknesses.
• Passive Trait Synergy: Check how the Rainbow unit's inherent passives align with the passive skills of your core creatures.
• Material Readiness: Verify that you have saved enough growth resources to level the creature immediately upon unlock.

Resource Management and Nurturing Strategy

Once you unlock your chosen Rainbow creature, focus your training routine on refining its primary attributes rather than splitting investments.

1. Direct Investment: Feed your highest-grade experience items and stat-boosting fruits directly to your chosen Rainbow unit until it reaches its cap.
2. Targeted Attribute Growth: Monitor stat allocation during the nurturing process, tailoring growth toward specific attributes such as Attack or Speed based on the unit's battle role.
3. Currency Pacing: Balance short-term event spending against currency required for guaranteed pity thresholds or late-stage event shop unlocks before committing your balance.

Squad Integration and Battle Positioning

After leveling your limited unit, integrate it into active combat formations to make full use of its stats:

• Reaction Chains: Position the new creature to set up or trigger elemental reaction chains with your existing party members.
• Loadout Optimization: Equip gear that enhances the unit's primary growth stat and supports its designated role in the team formation.
