Mecharashi: Ada and ST Hasteraze Full Rainbow Guide

To maximize the performance of Ada and ST Hasteraze in Mecharashi, prioritize upgrading all mecha parts to full rainbow status to achieve peak base stat scaling. Once you reach this upgrade threshold, shift equipment away from standard defensive stats toward critical damage, armor penetration, and weapon-specific offensive modules while keeping both units close together on the battlefield to execute high-damage burst rotations.

Full Part Rainbow Upgrades and Stat Scaling

Reaching full rainbow part status represents the maximum upgrade threshold for ST Hasteraze and Ada. This tier fundamentally alters their battle efficiency by applying heavy base stat multipliers. These increased stats allow your attacks to consistently penetrate high-armor targets found in end-game challenge stages without relying solely on external armor-shredding buffs.

Because reaching the rainbow threshold requires a heavy investment in duplicate pulls and upgrade materials, evaluate your resource pool before committing:

Save currency in advance to ensure you can reach the full rainbow threshold rather than stopping at lower intermediate tiers.
Determine if your account needs an investment in a dedicated carry unit before committing resources that could otherwise build roster depth.
Reserve sufficient materials to raise secondary support units who can apply debuffs and strip enemy shields.

Gear Optimization for Rainbow Tier Units

Once ST Hasteraze reaches full rainbow part status, its natural survivability increases through baseline defense and durability scaling. This defensive buffer lets you swap out traditional defensive accessories for offensive modules or utility components that speed up clear times.

Focus your gear configuration on stats that multiply raw attack output:

Module Focus	Primary Stat Priority	Recommended Usage
Offensive Burst	Critical Damage & Armor Penetration	High-armor end-game bosses
Utility & Speed	Cooldown Reduction & Mobility	Turn-limited speed-run stages
Support Synergy	Weapon Class Boosts & Proximity Buffs	Coordinated dual-unit strikes

Prioritize gear that matches the specific weapon class equipped by your setup. Boosting baseline attack stats through matching weapon gear prevents your damage output from being bottlenecked during high-tier encounters.

Battlefield Positioning and Skill Rotations

The combat effectiveness of Ada and ST Hasteraze relies heavily on tactical positioning. At full rainbow resonance, skill cooldowns and passive synergies align to sustain offensive pressure over multiple turns.

Maintain Proximity: Keep Ada and ST Hasteraze within range of each other during movement phases to trigger dual-unit passive support buffs.
Setup Debuffs: Use secondary squad members to strip enemy shields and apply defense down statuses before launching your primary attacks.
Execute Burst Windows: Target the enemy's destroyed or weakened body parts simultaneously during the same turn to eliminate high-HP bosses quickly.

Positioning these units too far apart on large maps disables vital proximity buffs, reducing their combined turn-by-turn damage efficiency.

Account Progression and Investment Strategy

Building a full rainbow unit serves as a long-term investment for your Mecharashi roster. High-tier stat scaling helps protect your investment against shifting game modes and tougher enemy stat pools in future updates.

However, over-investing in a single duo can leave your squad vulnerable in stages that require specific weapon types or elemental counters. Maintain a balanced team reserve by pairing Ada and ST Hasteraze with specialized support pilots who cover their mechanical weaknesses, allowing your main mecha to focus purely on part destruction and target execution.
