Flawless Arrangements
True Potential: In addition, target's CRIT Rate +20% and DMG dealt +20%.
Haruichi Izumo (Calculated Choice) is an Support who is really good as a single-target hyper buffer, designed to maximize the damage of a main DPS (“Battle Buddy”). While he doesn’t drastically change accounts that already have top supports, he is still one of the strongest offensive enablers currently available.
His core strength lies in True Potential, a unique buff that converts a large portion of Haruichi’s own CRIT DMG into bonus CRIT DMG for his ally. This makes his build highly CRIT-focused, as scaling his own stats directly boosts his teammate’s output. Alongside this, he provides SPD, ATK, Combat Skill DMG, ST/Blast DMG, and All Elemental DMG, creating a complete offensive buff package.
Gameplay-wise, Haruichi is a skill-spamming support, constantly cycling abilities to maintain buffs and generate value. His Clarity system rewards frequent skill usage by increasing his CRIT DMG and eventually granting extra skill points, helping offset his high SP consumption.
His Ultimate adds solid utility with guaranteed CRIT AoE damage and applies Assistance, a powerful buff that increases all elemental damage for his Battle Buddy (and later, the whole team with higher ascensions). He also provides this buff at the start of battle, ensuring immediate impact.
In terms of progression, A1–A2 are key breakpoints, adding CRIT Rate, DMG dealt, and more CRIT DMG scaling, significantly improving his consistency and support value. Higher ascensions expand buffs to the entire team and improve uptime, but are less essential.
Overall, Haruichi is a top-tier offensive support focused on amplifying a single DPS to extreme levels. He shines in bossing modes and high-end content, especially when paired with strong attackers. While not mandatory if you already own supports like Chester, he is highly recommended—particularly for players lacking premium support units or looking to optimize DPS-centric team comps.
