The Infernal Castle, featured in Arise Crossover, is an exclusive solo dungeon that opens for short 15-minute intervals. During each session, players should aim to progress through as many floors as possible to collect valuable rewards and recruit elite Shadows. This challenging event, also called the Demon Tower, is tailored specifically for endgame players who possess Shadows capable of inflicting quadrillions in damage (DPS).
Introduction to the Infernal Castle

The Infernal Castle consists of a challenging 100-floor structure that players must conquer without assistance. This solo aspect enhances the dungeon’s difficulty level. The event appears on the hour at xx:45, with “x”representing the current hour. After its spawn near the Leveling City vendors, players have a brief window of 10 minutes to enter the dungeon before the session begins, which is marked by a 15-minute countdown timer.
Due to the single-player restriction, players must rely heavily on their own DPS to defeat enemies and potentially recruit them as allies. Successfully eliminating an enemy grants an extra 60 seconds on the countdown, allowing for extended gameplay if one can maintain high damage output.
At every fifth stage, players will encounter a formidable boss, characterized by a substantial HP pool. These boss fights can be time-consuming, but they also offer an opportunity to recruit higher-ranked Shadows. The enemies vary in rank across the dungeon: starting with A-rank foes on the first 15 floors, progressing to S-rank adversaries from floors 16-29, and culminating with the challenging SS-rank enemies from floor 30 onwards.
Rewards for Conquering the Infernal Castle
Players can earn an array of rewards for their perseverance in the Infernal Castle, including:
- Shadows (with RNG determining ranks: A, S, SS, or G)
- Powder Dust (available in Common, Rare, and Legendary variants)
- In-game currency
- Gems
- Tickets obtained from boss encounters
Tips for Successfully Clearing the Infernal Castle

To conquer the Infernal Castle effectively, maintaining high DPS is crucial, with later floors demanding several trillion damage per second. Thus, this event is primarily suitable for seasoned players. The key strategy lies in swiftly dispatching enemies to avoid the countdown timer expiring.
It’s essential to assemble a team of the strongest Shadows available in the game. Players should focus on defeating and recruiting the most powerful opponents from the base game to enhance their chances of success.
Here are some recommended Shadows that will exponentially increase your chances of clearing the dungeon:
- Time King
- Ziru
- Mifalcon
- Murcielago
- Wind
- Sortudo
- Michille
By prioritizing these Shadows and leveling them to SS-rank, players can optimize their damage output and smoothly navigate through the Infernal Castle.
