Slotbound Deep Cave Stage 2 Guide: Clear It
Quick answer
Deep Cave is Slotbound's Stage 2, added in the v0.4.0 demo update on October 4, 2026 and playable up through Normal difficulty — the same official update note confirms this on the Steam news post. It is the demo's second and final area: run the same spin-to-summon, absorb-and-evolve loop you know from Open Forest, but against cave enemies (first-hand players describe waves of eyeball creatures) ending in an eyeball-style boss. A clear means surviving every wave and defeating that final boss.

What Deep Cave contains and how to unlock it
- The v0.4.0 update note on the official Steam news post states Stage 2, Deep Cave, is available up through Normal difficulty; before this patch, players report it was Easy only.
- Player playthroughs (Dabble) say the cave now goes to level/wave 20, versus the shorter Forest runs — plan your economy for a longer run.
- Several first-hand videos report Deep Cave unlocking as a new stage after clearing Open Forest runs; one player notes it appeared alongside their meta progression unlocks, on Easy at first. If it is not on your stage select, finish Forest difficulties and check the upgrades menu.
How to clear it
Enter Deep Cave from stage select
Pick Deep Cave at Easy or Normal; Normal requires the v0.4.0 demo build.Establish a frontline economy
First-hand clears show a Warrior-heavy board works: let tanks absorb damage up front while ranged or spell units deal damage behind them. Bank gold for interest and keep spinning within budget.Absorb fodder into a carry
Drag weaker units into your best unit to level it and stack abilities; one player reached advanced infantry units by mid-run this way.Beat the eyeball boss
Tommo's easy-mode clear ended with a full board of Warriors plus one Archer facing the boss he calls the Eye of the Beholder — a balanced, absorbed roster carried the fight.
Next steps
- If you keep dying on boss-type waves, the deeper enemy-wave prep advice on the Slotbound Hub beginner guide covers separate gold and blue-resource budgets for longer runs.
- For permanent power between runs, spend meta progression on interest, unit capacity, and life-loss prevention upgrades, which first-hand players credit for easier cave clears.
