Undercroft Deckbuilder Roguelike Heroes Guide: How Many Heroes and Who You Can Play Now

Quick answer

Undercroft: Deckbuilder Roguelike advertises 5 playable heroes, and the Knight is a hero you can start with right now: recorded gameplay shows the Knight offered and selectable at the start of a run, with a Cleric announced for November 16, 2026.

• The official Roblox listing states: 5 heroes, 300+ cards and 30 bosses (checked mid-November 2026).
• The Knight is confirmed playable now, and its starting deck includes the card Slash.
• A Cleric is announced: the update titled 'The Cleric Approaches — A new hero descends' is listed for November 16, 2026, but it is not confirmed playable yet.

How many heroes does Undercroft: Deckbuilder Roguelike have?

Five. The official Roblox listing for Undercroft: Deckbuilder Roguelike, the co-op card roguelike by group NEVER GIVE UP!!!!, advertises "5 heroes. 300+ cards. 30 bosses guarding the way down." As of mid-November 2026 that count stands, alongside the game's other headline numbers: more than 300 cards to build with and 30 bosses waiting at the bottom of each descent.

Treat the number as current rather than permanent. The game only launched on October 24, 2026 and had already been patched as recently as November 11, 2026, and a new hero is on the schedule (the Cleric, covered below), which would take the roster beyond five. After a major update, recheck the roster before assuming the count.

The listing counts the heroes without naming them. The names established so far are the Knight, which is playable right now, and the Cleric, which is announced but not yet in the game.

Cleric

The hero you can start with right now: the Knight

If you want a hero you can pick today, the Knight is the one verified in play. In recorded gameplay of a run, the Knight appears among the heroes offered when the run begins, and the player sets off down the dungeon as a Knight.

That same run shows what the Knight starts with and how it changes:

• Starting deck: the Knight's deck includes the basic attack card Slash, which the player uses in the run's early fights.
• Deck evolution: later in the descent, a relic choice offers to transform a card, and the player turns Slash into Kick the Fallen. Starting cards are a seed rather than a fixed build — transformations and post-fight card rewards reshape the deck as you go deeper. The deckbuilding guide and the cards list cover that system in detail.

One caution: the footage proves the Knight is selectable, not that it is the default or only hero. With five heroes advertised, the run-start hero selection shows other choices alongside it — the Knight is simply the hero confirmed by name in gameplay so far.

A Cleric hero is scheduled to descend

The roster is set to grow. An update tracker lists an upcoming release titled "The Cleric Approaches — A new hero descends" for November 16, 2026, which announces a Cleric hero and would take the roster beyond the advertised five. The schedule entry does not confirm the Cleric is playable or say how it is unlocked, so treat the Cleric as announced rather than playable until the update actually lands. The updates page is where new hero releases show up first.

What your hero choice means in a run

You pick a hero at the start of a run, and that choice shapes the deck you build from there. Undercroft: Deckbuilder Roguelike is a co-op card roguelike for 1–4 players inspired by Slay The Spire 2: you pick your path downward, build your deck as you go, and fight the bosses guarding the way down. Leaving does not end the run — the descent is saved, so you can continue any time and a Knight run does not need to be finished in one sitting.

For what surrounds your hero: the runs guide explains how a descent fits together, the paths guide covers route choices, and the combat guide plus the bosses guide cover the fights your hero's deck has to win.
