Echo Abyss AI dungeon

Echo Abyss beginner guide: type what you do

Echo Abyss is not a click-through RPG. You write a sentence in plain language; the AI Dungeon Master turns it into something that happens in the dungeon.

Start in under a minute

Open Echo Abyss, enter a name, then choose an API. The official API is free but slow. Your own DeepSeek key is faster and is billed by DeepSeek. No account and no download are required.

How a turn works

  1. You type an action: “I press my ear to the left wall”, “I swing at its underside”, “I ask the merchant about the key”.
  2. The server resolves damage, stealth, gold, items, depth, statuses and bosses.
  3. The Dungeon Master writes the result and offers three next actions.
  4. You continue. Specific actions work better than “continue”.
Descent lock: you must explore at least two turns on a floor before going down. If you linger too long, the DM will point you toward the stairs.

Combat, chests and gold

Every monster has a weakness. Fire hurts moss and spiders; silver hurts wraiths; names unsettle the faceless. When you find a chest, you write what is inside. The game reads names and uses them: a book raises Intelligence, a blade becomes a weapon, a potion heals, a key becomes a clue.

Gold buys from the mysterious merchant. The merchant is not guaranteed to appear; when present, stock and prices are random. You can haggle in the input box.

Ten floors and the Heart

Floor 9 has the Abyss Guardian. Defeat it to reach Floor 10, take the Abyss Heart, then climb back to the surface while the Abyss wakes. At Awakening 10 the Abyss Lord appears. You can fight it or keep running. There are 13 fixed endings; the hidden one requires three clues on Floors 3, 6 and 8.

Five beginner tips

  1. Explore the first two floors before descending.
  2. Write what you use and where you strike.
  3. Carry a healing potion before Floor 3.
  4. Retreat, distract or negotiate when a fight is bad.
  5. Check Floors 3, 6 and 8 if you want the secret ending.

Enter the dungeon

Free to start. No download. If you do not know what to type, begin with “I walk down the stone steps.”
