Pros & Cons for Jura Igarashi (Grit and Duty)
Blunt/Fire Support With Blast Attacks
Jura Igarashi is a 5★ Support with dual Attributes, Blunt and Fire, capable of using Blast Attacks with both via her Combat Skill and Ultimate.
Strong Synergy With DoT Teams
Jura can inflict Burn with her Ultimate and apply Afterburn, which deals additional DoT based on a fixed percentage of total DoT taken. In addition, her Passive Skill increases the entire party's DoT DMG Multiplier when her Effect Hit Rate reaches 70% or higher, making her especially effective with DoT-focused characters like Akari (Festive Christmas).
| Tip! | Since she boosts allies' DoT DMG Multiplier, aim to reach at least 70% Effect Hit Rate on Jura. |
|---|
Boosts Damage, SPD, and Utility
Hot-Blooded, granted to all allies via her Combat Skill, increases DMG dealt, ATK, and SPD. Additionally, attacking Kaiju affected by Afterburn increases allies' DEF PEN Rate. After using a Normal Attack, she can also boost all allies' Effect Hit Rate.

A2 allows Afterburn to be applied to all Kaiju at the start of a wave, A4 applies Burn to all Kaiju at the start of a wave, and A6 further improves performance by applying Afterburn to all Kaiju and increasing allies' ATK when attacking debuffed enemies.
