Infinity Castle
Inspired by Demon Slayer — Muzan's Infinity Castle (Final Battle arc)
Mechanics & Mode
Raid Mode arena (Raid 1 of 3). Drops Raid Coins (used at Raid Shop for trait spins, lucky spins, cosmetics, abilities).
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 arena is named on the official Trello “About Raid” card, which mirrors the developer’s Discord channel — and the visual is one of the most recognizable Demon Slayer locations.
Mode pairing: Raid only. Infinity Castle is not in the rotation for Survival, Infinite, or Titan Defense modes.
Reward economy: Raid completions drop Raid Coins, which are spent at the Raid Shop for trait spins, lucky spins, cosmetics, and abilities.
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 — it applies across all three raid arenas, including Infinity Castle.
Raid Mode economics that apply to Infinity Castle
The rules from the Trello “About Raid” card govern Infinity Castle along with the other two arenas:
- Co-op size: 1-6 players per raid
- Boss HP scaling: boss HP scales with party size, which is why endgame players generally prefer solo runs for faster farming
- Ticket cost: the first three raids in the rotation cost 1 ticket each, and later raids (4/5) cost 5 tickets each — Infinity Castle as “Raid 1 of 3” sits in the 1-ticket bracket
- Coin reward: 31-76 raid coins per boss kill, spent at the Raid Shop for trait spins, lucky spins, cosmetics, and abilities
- Drops: cosmetics, titles, abilities, and lucky spin rewards
Quick facts
- Raid #: 1 of 3
- Entry cost: 1 ticket
- Payout: 31-76 raid coins per kill, spent at the Raid Shop
- Party size: 1-6 players, with boss HP scaling by party size
- Best trait: Reaper
The three raid arenas
| Arena | Raid # | IP reference | Entry cost | Payout |
|---|---|---|---|---|
| Infinity Castle | 1 | Demon Slayer — Muzan’s palace | 1 ticket | 31-76 raid coins per kill |
| Shadow Garden | 2 | The Eminence in Shadow — Cid Kagenou’s organization | 1 ticket | 31-76 raid coins per kill |
| Western Land | 3 | Western theme | 1 ticket | 31-76 raid coins per kill |
All three arenas share the same entry cost, coin payout, and 1-6 player co-op structure, so the choice between them comes down to which IP you prefer and how each boss feels in your run.
How Raid compares with Survival and Infinite
| Mode | Format | Maps | Rewards |
|---|---|---|---|
| Raid | Boss fight, 1-6 player co-op | Infinity Castle, Shadow Garden, Western Land | 31-76 raid coins per kill; cosmetics, titles, abilities, lucky spin rewards |
| Survival | 6 sections + 30-second pre-boss wave + boss fight, 4 difficulty tiers | Shibuya, Impel Down | Normal and lucky spins, abilities, gadgets, trait rerolls, raid tickets |
| Infinite | Endless waves, a boss every 5 waves | Shibuya, Impel Down | Higher wave = better rewards; materials over long runs |
Why farm here
The raid drop table is the same across all three arenas — cosmetics, titles, abilities, lucky spin rewards, plus 31-76 raid coins per kill. The practical reason to pick Infinity Castle is the 1-ticket entry cost (raids 1-3 sit in this bracket) combined with solo-run boss-HP scaling for faster clears. The Raid Shop is where coins convert into trait spins, lucky spins, cosmetics, and abilities.
Where raid tickets come from
Survival runs drop raid tickets, and several codes pay them out directly: 5KFOLLOWERS! (40), SORRYFORDELAY (20), SBRUPDATE (15), BEYONDTHEWALLS (15), THANKSFOR7KPLAYERS (15), and NEWGAMEMODE (10). At 1 ticket per raid for raids 1-3, a single code covers many Infinity Castle runs.
Synergies & comparison
Infinity Castle sits exclusively in the Raid Mode rotation alongside Shadow Garden and Western Land — none of these arenas overlap with the Survival/Infinite maps (Shibuya, Impel Down) or with Trost’s Titan Defense mode. For trait pairing, Reaper is the consensus best Raid trait, which is why the Reaper Burst Build linked above is recommended across all three arenas, including Infinity Castle.
