Pros & Cons for Iharu Furuhashi (Flash-Fierce Talent)
Shot/Lightning Attribute Attacker
Iharu is a Blast Attacker with Shot/Lightning Attributes. His Combat Skill, Ultimate, and Overflow attack allow him to perform dual-Attribute Blast Attacks, making it easier to reduce enemy PLT.
High-Frequency/Multi-Hit Additional DMG
Iharu deals high-frequency/multi-hit Additional DMG. He applies Additional DMG 10 times with his Ultimate, 5 times with his Combat Skill, and 15 times with his Overflow attack.
Pair with Additional DMG Allies
Iharu can grant himself "Menace," which increases his Additional DMG Multiplier after an ally deals Additional DMG, making him a character who benefits from being paired with allies that deal Additional DMG.
Overflow Attack & Additional DMG on Blitz
At the start of battle, a fixed-SPD Blitz Turn appears, and when it arrives, Iharu can activate an Overflow attack with dual-Attribute Blast Attack & Additional DMG.
After the Overflow attack, all Menace stacks are consumed, so it is ideal to pair him with Additional DMG allies to build up Menace more easily. However, the Selfless Flow granted by his Ultimate does not consume Menace.
Aim for A2 First
A1 increases damage, while A2 grants Menace after the Ultimate and extends the duration of Selfless Flow by 1 turn. This helps conserve Menace and provides further damage gains, making A2 the recommended target first.
If resources allow afterward, A4 adds additional PLT destruction, while A6 enables extra Additional DMG and Blitz Turn SPD 100, further enhancing his performance.
