Ryo is a support who enhances team tempo and overall damage output. With his Ultimate, he grants allies both a DMG Dealt and SPD buff, allowing your team to act before the Kaiju and increase the total number of attacks within a rotation.
His Passive Skill further boosts the team by increasing the ATK of all allies except himself unconditionally. Since this effect does not consume SP, Ryo provides consistent offensive support while remaining easy to slot into almost any team composition.
Ryo scales exceptionally well with Ascensions. At A4, the duration of his buffs is extended, improving overall uptime and consistency. At A6, he continuously grants allies a DMG Dealt buff, significantly increasing sustained team DPS. If you plan to invest in him long-term, pushing his Ascensions is highly recommended.
