The endless depths: reaching floor 10

1,161 players hold Deep Diver. It is one of the smallest numbers in the game, and it is reachable — here is what changes by floor.

Quick answer

Build for sustain, not burst, in the depths. You are not racing a boss timer — you are surviving a chain of fights with no full reset, so healing and card draw beat one big hit.

1,161 players have reached depth 10 in the endless depths (Deep Diver). Out of 59,582 players who finished the first quest, that is 1.9% — one of the smallest numbers in the game outside the level-60 badge.

It is also the most predictable endgame ladder in Arcane 101, because it is the one place where the winning strategy inverts.

More players have cleared a Mythic tier than have reached depth 10 — by a factor of four. The depths are the least-trafficked progression content in the game.

Why the strategy inverts

Every other mode in Arcane 101 is a discrete fight: you enter, you clear, you reset. Attrition does not carry over, so burst damage is king and a big single hit is always the right upgrade.

The depths are a chain. You descend floor by floor without a full reset between them. That changes what "good" means:

  1. Sustain beats burst. A card that heals or draws keeps you alive across ten floors. A card that hits for the most damage but empties your hand does nothing on floor four.
  2. Card draw is a defensive stat. Running out of options is how runs end, more often than running out of health.
  3. Consistency beats ceiling. You are not trying to win one fight fast; you are trying not to lose any of ten.

If you built your deck for the campaign — one big carry card, maximum damage — you have built exactly the deck that fails here. That is the whole reason 1.9% of players are in this badge.

The preparation checklist

  1. Finish the campaign first. You need the card pool, the gear and the levels. There is no shortcut into the depths.
  2. Have two damage cards at a real tier, not one.Card tiers — this is the one place where the "one card only" rule relaxes, because you need a second source when the first is out of cards.
  3. Include at least one sustain option — healing, shielding, or draw. If your deck has none, that is your build problem, not your level problem.
  4. Wear your legendaries — gear. Attrition content rewards every small modifier.
  5. Run the first three floors as a test, then stop. Note which floor your health first drops below half. That number is your real depth. Do not push past it on a run you care about.
  6. Add one sustain card, re-run. If your "health first below half" floor moved down by two or more, sustain is the right axis and you should keep stacking it.

What we do not know

The floor-by-floor enemy roster, the reward table, and whether the depths have a fixed or generated layout are not published by the developer and we have not verified them. This page is about the build axis, which is the transferable part: in a chain of fights, survivability compounds and burst does not.
