Pros & Cons for Reno Ichikawa (The Compatible User)
Ice Damage Dealer
Reno applies Ice Crystal to enemies with his Combat Skill. When an ally attacks a Kaiju marked with Ice Crystal, it triggers bonus damage, making Reno a great status inducing character.
Can Spread Ice Crystals
With his Passive Skill, Reno can spread Ice Crystal to nearby Kaiju after using a Combat Skill, Follow-Up Skill, or Ultimate on a target already affected. This lets him blanket the battlefield in Ice Crystals and an ace against multiple targets.
Freezes Enemies to Disrupt Their Turns
Reno's Ultimate can inflict Freeze, a status effect that delays the enemy's action order. This status effect is useful especially for extending the Core Exposed state of Kaijus or to interrupt their attacks.
Dual-Attribute: Physical and Elemental
Reno is a character who can deal both Shot and Ice damage. Since he can reduce both Physical RES and Elemental RES, he is a flexible pick which can work in most squad formations.
Skill with SP Regen Chance
Upon reaching Level 40, Reno gains a chance to recover SP after using a Combat Skill. More SP means more opportunities for your entire party to unleash powerful skills, so having a built-in recovery mechanic makes Reno a valuable asset in any battle.
Best Team Comps for Reno Ichikawa (The Compatible User)
High-Damage Ice Crystal Squad Setup
This squad setup features 4★ Mina, whose ATK boost maximizes Reno's Ice Crystal damage. Since Reno can spread Ice Crystal by triggering his Follow-Up Skill on enemies already in the Ice Crystal state, coordinate with a high-damage partner to quickly reach Core Exposed.
