Dungeonbound Co-op Climb Guide: How 2-4 Player Runs Work

The one rule that defines co-op

Each player keeps a separate purse, shop shelf and relics. The team shares five hearts.

That is the official description, and it produces a very different game from a typical co-op roguelike. You cannot pool gold to carry one player. You cannot buy the same shop item for the whole team. What you can do is share the consequence of a weak board: if one player keeps losing fights, the whole team loses hearts.

So the team’s job is not to make one hero strong. It is to make the weakest board strong enough to survive its floor.

How a co-op run plays

The official loop:

1. Host a lobby and pick heroes. The Halloween update added open lobbies, a Find Lobby browser, team chat and host kick tools.
2. Each player gets their own purse and shop shelf. Relics are also separate, so two players can build around different rules.
3. Fighters step in one after another. The rest of the team watches the battle live.
4. Loot is rolled. When a foe drops loot, everyone picks what they want and the dice settle any argument.
5. Gear can be gifted. Drop a piece onto a teammate’s board to hand it over. Co-op-only items reward giving them away.
6. Team rivals are whole parties. Your opponents are parties built from other players’ climbs, not solo snapshots.
7. Leaderboards are split by team size: two, three and four players.

A saved climb per team means you can resume later. If someone quits, a bot can replace them. There is also a Quick Join option and a ping display, added in v0.1.51.

Build roles, not clones

Because shops are separate, four players chasing the same tag will compete for the same drops and leave the team with four identical weaknesses. A more robust team plan:

1. One frontline / attrition board

A Paladin-style Block, healing and Thorns plan is the natural anchor. The official Paladin description is “the sturdiest start, with the most Block. A slow swing, and a tree of healing and Thorns.” In co-op, that board can absorb the fights the others cannot.

2. One fast damage board

A bow or burst plan that closes fights before the enemy’s status engine comes online. The Archer’s confirmed bow-and-ammo package is a clean example, especially with the Fletcher’s Garnet ammo gem.

3. One status / control board

Burn, Poison, Freeze or Stun pressure. Statuses tick on their own clocks, and the team’s damage windows do not have to line up perfectly if the enemy is already losing health between turns.

4. One flex / economy board

A player who can take the co-op-only gifting items, pass gear across the table, and fill the tag the team is missing. Do not treat this as the “weak” role; a flexible board is how a team recovers from a bad shop.

This is a planning template, not a tier list. The game does not publish co-op-specific balance data, and the best composition depends on the relics and shops the team actually sees.

Five shared hearts means five shared mistakes

The heart pool is the team’s real health bar. A few practical rules:

• Do not spend the last heart on a speculative floor. If one player is clearly under-geared, let them take the safer shop and farm the easier fight.
• Gift the item that fixes a weakness, not the item with the highest rarity. A common sustain piece on the player who keeps dying is worth more than a legendary damage piece on the player who is already winning.
• Call out your damage type. A team of four physical boards into a high-Block rival is a preventable loss.
• Use the ping and chat. The game gives you both; use them before the battle, not after.
• Agree on relic roles. Separate relics are an advantage only if the team uses them for different jobs.

Loot dice and gifting etiquette

The dice settle disputes, but they do not settle strategy. Before the roll, ask:

1. Who can actually equip it? Class-bound gear only drops for heroes who can use it, but a piece can still be a better fit for a teammate’s tag plan.
2. Is it a space upgrade or a sidegrade? A large item can hurt a teammate whose board is already full.
3. Does it trigger a co-op-only gifting bonus? The Steam page says co-op-only items reward giving them away, so the “greedy” choice is not always the selfish one.

If your group uses voice chat, nominate one player to call the loot priority for the floor. It is faster than resolving every drop with a dice roll.

Team rivals and leaderboards

Team rivals are whole parties built from other players’ climbs, which means the opposing side has the same composition problems you do. Scout the party, not just the first board:

• Which player is the damage carry?
• Which player is the sustain anchor?
• Does the party have a status plan, or four independent damage boards?
• Are their relics visible in the scout panel? If so, what rule did they bend?

Co-op leaderboards are separate for teams of two, three and four, so a four-player clear is not directly competing with a duo. That is a healthier ladder than a single pooled board, and it makes “we cleared it with two” a meaningful result.

Setting up a run: a short checklist

What we still don’t know

• Whether co-op has dedicated matchmaking beyond open lobbies and Quick Join.
• Whether team rivals scale to the party’s average floor or the host’s.
• Whether co-op-only items have a full set or a small curated pool.
• Cross-platform support (the game is listed for Windows PC only).
• Whether co-op rank is shared, per player, or per team.
