Pros & Cons for Reno Ichikawa (The Reigning King of Kaiju)
Buffs Allies' Damage with Attunement
Reno can grant Attunement to a single ally via Combat Skill, increasing their ATK.
Additionally, while the target is under Attunement, activating Enhanced Normal Attack increases Combat Skill DMG, while Ultimate increases DMG dealt. With the Additional Passive Skill, the Attunement target's CRIT Rate can also be increased by 20%, further boosting their damage.
Enhanced Normal Attack While in Frozen Soul
Reno enters Frozen Soul after activating Combat Skill, making Combat Skill unusable and changing Normal Attack to Enhanced Normal Attack.
After the count from activating Enhanced Normal Attack reaches 3, Frozen Soul and Attunement are removed after the turn. When manually applying buffs, check the target character to ensure they are applied to the intended ally.
Has Self-Buffs for Damage UP and Action Order UP
Reno has DMG Dealt UP and Ice DMG Dealt UP for himself, CRIT Rate UP for Enhanced Normal Attack and Ultimate via Additional Passive Skill, and CRIT DMG UP based on his ATK. These multiple buffs allow him to increase his own damage further.
Additionally, he can increase his own Action Order at the start of battle or via Combat Skill.
Aim for A2 First
At A2, Reno can increase CRIT DMG for allies and himself, further enhancing allies' damage, making A2 the recommended first target. Reaching A6 also allows him to further boost both allies' and his own damage.
