Depth Spelunking Hard Mode Guide — Rules and Survival Tips

Hard Mode is Depth Spelunking’s optional cruelty dial—added in the Recode (v0.7.0a) and tightened again in v0.7.0b. It uses the same expedition loop as Classic, but starving resources, sharper tasks, and earlier event entities leave little room for careless sprinting. This guide lists every verified rule change and how to adjust your floor rhythm.

Community wikis once hosted only a placeholder Hard Mode page; if a source still looks empty, rely on the official log lines below. Verified against v0.7.0b (2026-11-09).

What is Hard Mode in Depth Spelunking?

Hard Mode is a toggle difficulty layer, not a separate game. You still:

• Clear task quotas on procedural floors
• Manage elevator power and reboarding timers
• Vote on upgrades at the terminal

What changes is density and cost: more entities sooner, fewer reliable consumables, harder task minigames, and event pressure starting almost immediately.

If you are still learning task routing or elevator doors, finish the beginner guide on Classic first.

How does Hard Mode change entities and spawns?

Hard Mode accelerates the entity budget curve—especially in the first dozen floors where Classic lobbies feel sparse.

Key differences:

• More entities per floor, climbing faster as depth increases
• Eris (bonus dangerous spawns) is more common, and v0.7.0b allows Eris from Floor 2 onward on Hard—far earlier than Classic’s event timing
• Standard threats (Warden, Lurker, Sloth) still teach the same counters, but you meet them in parallel, not one at a time

When Eris fires, she injects a random dangerous entity until you descend (Eris lists the pool). On Hard, assume event pressure starts almost immediately.

Why do consumables feel broken on Hard Mode?

Hard Mode throttles floor loot:

• Consumable spawns are rarer
• Many pickups resolve as scrap instead of full heals or buffs
• Client-side item copies (v0.7.0a+) mean you cannot rely on teammates’ leftovers

Bring dependable starter sustain—Medkit, Halo, or Providence per the 0.7.0a/b item notes—and assume vending machines may disappoint. Item tuning lives under patch notes 0.7 and best starter items.

How do Hard Mode tasks differ?

Official 0.7.0b notes call out harder tasks globally; Hard stacks that on top of the mode’s baseline.

Practical symptoms:

• Multi-step jobs (pipes, calibrators, coordinators) take longer, eating elevator power
• Failure resets on puzzle tasks punish panic inputs
• Sound-heavy objectives still call Warden attention—worse when multiple players split up

Official 0.7.0b notes call tasks harder globally; Hard stacks that on top of the mode. Longer minigames drain elevator power—each finished task still refunds +15% power per the elevator rules in beginner guide.

Habits tied to published rules:

1. Loud tasks still pull Warden attention—one player on the noise, others crouch.
2. Finish longer jobs before the last task when power is tight.
3. Skip votes need squad agreement; skip spam risks Malfunction (elevator wiki behavior).

Shrines, revives, and ghosts on Hard runs

v0.7.0b brought two quality-of-life rules that matter on long Hard ladders:

• Shrines of Soul can spawn on ordinary Hard floors (not only scripted rooms)
• Shrine revives no longer disqualify leaderboard badges below Floor 100

Paid revives still cap at two per run (50 Robux, then 80 Robux, or free meta currency). Worship upgrades add +5% shrine odds in Break Rooms. Full economy breakdown: how to revive.

If you wipe without revives, Post Mortem ghosts can scout; Manifest Presence gained a global cooldown in 0.7.0b per the DevForum log. Ghosts still cannot finish tasks (how to revive).

Hard Mode vs Daily Mode — which should you queue?

Hard Mode trains consistency across floors; Daily tests optimization on a known seed. Many players alternate: Daily for warmup, Hard for income.

Boss windows on Hard Mode

Boss probability still follows Recode globals:

• No bosses before Floor 20
• 7% boss chance per floor from Floor 60
• 10% from Floor 100

Hard does not exempt you from the Envy guaranteed Sin window (Floors 20–24). Plan sin mechanics before you queue Hard past Floor 19.

Hard Mode is Depth Spelunking’s honesty check: fewer consumables, sharper tasks, and Eris from Floor 2 on 0.7.0b. Master the elevator loop on Classic, then climb Hard for the +10% purse and the separate leaderboard. Deeper floors still follow global boss odds from patch notes 0.7.
