Undertale Adventures X Raids and Gauntlet

The story Acts are only part of Undertale Adventures X. The lobby has ten facilities, and six of them are side modes that pay different currencies: Raids, Gauntlet, AFK Chamber, Challenges, Infinite and PVP. This page covers what each one actually does, and flags the ones the game has not documented.

• Raids — separate encounters with their own rewards
• Gauntlet — area gauntlets that pay Toby Tokens plus area tokens
• AFK Chamber — timed item payouts
• Challenges — daily and 30-minute runs for evolution materials
• Infinite — endless scaling waves with leaderboards
• PVP — exists, rules undocumented

Raids

The community wiki's entry for Raids is short: "Raids is an important part of the Lobby. Here, you can attempt various Raids, each rewarding you differently."

That is the whole documented description. There is no published raid list, no boss names and no reward table, so this page does not invent any. What is safe to say:

• Raids are a separate content type from story Acts.
• They reward differently per raid, which means they are the place to look when a specific material is missing from Act drops.
• They sit in the lobby, so they are accessible without travelling.

If you are stuck on a material, check Raids before assuming the game has no source for it.

Gauntlet

Gauntlet is the mode with the clearest documented reward. The wiki states: "Here, you can attempt Gauntlets of the Story Areas and get Toby Tokens and tokens for their respective Area."

Two currencies follow from that sentence:

• Toby Tokens — a global Gauntlet currency.
• Area tokens — one per story area, earned by running that area's Gauntlet.

Area tokens are the interesting part, because they are the only documented currency that is tied to a specific zone. That makes Gauntlet the likely answer to "how do I get more of the thing that only Waterfall gives me" without grinding Waterfall Acts.

The Gauntlet is also a good difficulty check. If you can clear an area's Gauntlet, you are over-geared for that area's Acts, which means you can push to Act 6 for the better drop rates.

The AFK Chamber

The AFK Chamber is the lowest-effort mode in the game. The wiki describes it as a place where "you can wait for payouts every (x) seconds, which have various Items."

The interval is not published, and neither is the item pool, but the mechanic is straightforward: stand in the chamber, receive payouts. There is no reason not to use it while you are reading a guide, waiting for a friend, or between runs.

The practical habit is to end every session in the chamber rather than in the lobby's menu. It costs nothing and the payouts are items you would otherwise have to farm.

Challenges

The Challenges room has two modes, and they are meaningfully different:

• Daily challenge — harder, better rewards.
• 30-minute challenge — easier, smaller rewards.

The wiki describes the rewards as things that "help you progress in the game, such as generic evolution items," and adds an important constraint: the challenges require specific Units that are boosted by that challenge. If you bring the wrong team, you cannot clear it regardless of your Units' overall strength.

That constraint makes Challenges the one mode where reading the modifier matters more than reading your roster. Check which Units are boosted before you queue, and do not treat a failed challenge as a signal that your team is weak.

Infinite Mode

Infinite is the endless wave mode. The wiki's description:

• It pays Souls, XP and Underpass XP, plus other materials.
• Enemies grow stronger with each wave, so surviving longer is the score.
• It has leaderboards and exclusive titles for top placements.
• It recommends bringing a farm-type enemy Unit.

The farm-type recommendation is the important detail. Infinite rewards income scaling, so an economy Unit that accelerates your board is worth more there than a pure damage Unit that peaks early.

Infinite is also the cleanest way to find your team's actual ceiling. Story Acts are fixed difficulty; Infinite is a slope. If you fall over at wave 12, that number is your real power level, and it is a better progress metric than "which Act am I on."

PVP and Trading Hub

Both facilities exist in the lobby, and both are under-documented.

PVP — the community wiki's page is still a placeholder, reading "Here, you can fight other players for (rewards) - both part and rewards is placeholder." The mode exists; its rules and rewards are not published. Do not plan progression around it.

Trading Hub — the lobby map lists it as a facility. No trading rules, restrictions or currency are documented. Treat it as a social space until the game explains otherwise.

Documenting what is missing matters here, because a page that invents PVP ranks or trading prices would send players into a mode with wrong expectations.

How the Side Modes Fit Together

The efficient weekly loop uses each mode for what it is actually best at:

That is a healthier spread than grinding one mode, because the currencies do not overlap much. Acts give Souls and Gold; Gauntlet gives tokens; Challenges give evolution items; AFK gives miscellaneous items.

Unlocking and Requirements

The lobby lists all ten facilities from the start, but that does not mean all of them are usable immediately. Challenges explicitly require boosted Units, and Infinite requires a team that can survive scaling waves.

The practical unlock order for a new account is:

1. Story Acts until you have a four-role team.
2. AFK Chamber immediately, because it is free.
3. 30-minute Challenge once your team can clear Ruins Act 6.
4. Gauntlet for the area you are farming.
5. Infinite to measure your ceiling.
6. Raids and daily Challenges once your damage Unit has traits.

The beginner guide covers the first three steps in more detail, and the Souls guide covers the Act farming loop these modes supplement.

Frequently Asked Questions

What are Raids in Undertale Adventures X? Separate lobby encounters that each reward differently. The game does not publish a raid list.

What are Toby Tokens? The currency earned from Gauntlets, alongside area-specific tokens.

How does the AFK Chamber work? It pays out items on a timer while you are in it. The exact interval is not published.

What is the difference between the daily and 30-minute challenge? The daily is harder and pays more; the 30-minute is easier. Both give evolution materials.

Can I do Challenges with any team? No. Each challenge boosts specific Units, and you need those Units to clear it.

Is PVP worth playing? It exists, but its rules and rewards are undocumented, so it is not a progression route.
