Villain Dimension

Open it from PLAY. Each Dimension runs waves, a miniboss, and a boss. The September chart names these bosses: All For One, Shigaraki, Nomu. Card tier on that chart: Rare to Epic. Easy, Hard, and Nightmare change enemy health and the card table. Nightmare is the accessory farm for several early pieces. An older page put Demon Dimension at level 16 with different bosses. If your selector shows another level, use the selector. Extreme Dimension is a separate October revamp and is not this row.

Account level 15+, then PLAY.
