NEEDS CHECK
Infinity Castle is the first of three Raid Mode arenas in Anime Apocalypse, themed after Muzan’s labyrinthine palace from the Demon Slayer Final Battle arc. The map is named in the official Trello “About Raid” card (w3KsrWKJ) which is mirrored from the developer’s Discord channel — making the map name itself Tier 1 / Discord-attested.
Mode pairing: Raid only. Infinity Castle is not in the rotation for Survival, Infinite, or Titan Defense modes per the Trello roster.
Reward economy: Raid completions drop Raid Coins which are spent at the Raid Shop for trait spins, lucky spins, cosmetics, and abilities. The exact drop rates and the specific boss roster for the Infinity Castle arena are not enumerated in any current source — both Trello and Pro Game Guides describe Raid Mode at the system level rather than per-arena.
Recommended build: The site’s Reaper Burst Build (Spin · Head of Hei · Akaza · Coyote with Reaper trait, Battle Suit + Rage gadget) is the recommended Raid Mode loadout — applicable across all three raid arenas including Infinity Castle.
Why we flag this entry as verified_single_source: The map name and the fact that it is one of three raid arenas come from Trello (Tier 1). Aggregator coverage of Infinity Castle as a standalone arena is currently absent — Beebom, PGG, BloxInsider, and FFBooyah all describe Raid Mode generically without naming the three arenas. Once a Discord screenshot, FAQ post, or aggregator deep-dive surfaces details on the boss roster or unlock gate, this page will be promoted to verified and the gaps filled.
