Probably No One Else is Doing This

Velvet Room Trial Iluwind 28 Give Joker the Persistent Damage Revelation, use Moco for Status Ailment Hit Rate Up, Mona for 1MORE, on the first turn use Wonder's Da Capo on Anju to give Joker Solone's unique skill, and use Skadi on one of the enemies to inflict dizziness. Joker just spams Skill 1 to apply Seals and Burn. Solone's unique skill randomly applies Burn to one target, and the base chance for applying Seals is 20%. However, this super RNG-dependent game was a lot of fun. By the way, it seems the Burn effect from Solone's unique skill also applied a 6x score multiplier.
