Gravewell Guide: How to Survive Deeper in This Idle Dungeon RPG

Gravewell is a dark fantasy idle dungeon RPG built around one loop: pick a hero, descend the dungeon floor by floor, watch the auto-battles play out, and die deeper than you did last time. It is a roguelite dungeon crawler you can play with one thumb, in portrait, in the time it takes to wait for a bus.

If you have never played an idle RPG or an auto-battler before, this guide walks through how a run actually works, what each choice on the dungeon map does, and the habits that separate an early death from a deep one.

What is an idle dungeon RPG?

In a traditional dungeon crawler you control every swing. In an auto-battle RPG like Gravewell, your hero fights on their own. Attacks, crits, poison ticks, and boss abilities resolve automatically while you watch the damage numbers roll.

That does not mean you do nothing. It means your decisions move up a level. You are not choosing when to swing, you are choosing:

  • Which path to take across the dungeon map
  • Which loot to equip across six gear slots
  • Which passive you carry into the descent
  • Which stat bonus to take on every level up
  • When to spend gold on healing instead of gear
  • When a boss is going to kill you, and whether to push anyway

The fighting is idle. The build is not.

How a run works

Every run in Gravewell is a fresh roguelite descent with permadeath. You start at the top of the well with a base hero and nothing but your permanent upgrades, and you work your way down.

Each floor is a small branching map. You tap a node, your hero travels there, and something happens. The node types are:

  • Fight and Elite: standard enemies, and tougher ones with real abilities. Elites hit meaningfully harder than the pool around them.
  • Boss: every floor ends with one. There are 99 handcrafted dungeon bosses.
  • Treasure: a chest, usually gold and sometimes gear.
  • Vault: gear behind a price. Pay to unlock it, or force it open and take the damage.
  • Merchant: a shop with a handful of items for sale, plus a heal you can buy. The heal price climbs the deeper you go.
  • Shrine: a choice with a cost. Shrines always want something in return.
  • Fountain: healing without the negotiation.
  • Event: a written encounter with branching options and real consequences.
  • Hazard: exactly what it sounds like.

Clear the floor, take the boss, and you descend. Your health carries over between floors with only a partial heal on each clear, so attrition is the real enemy. A regular fight costs you about 6% of your health and a boss costs about 23%, which means the floor in front of the boss decides the boss.

The five heroes

You pick a hero at the start of every descent, and each one plays the dungeon differently:

  • Warden (Steady Blade): sword, shield, no weak spots. The baseline every other hero is a variation on.
  • Bulwark (Living Wall): crystal plate and a heavy hammer. Highest health and defense in the game. Soaks punishment that would end anyone else.
  • Duskblade (Killing Edge): light armor, quick blade. The highest crit rate on the roster, carried on one of its lightest health pools.
  • Bonecaller (Blood Debt): the only hero who starts with lifesteal, paid for with the lowest defense in the game.
  • Relic Hunter (Gold Rush): a little softer than the Warden across the board, and earns 30% more gold to spend at merchants on gear and heals.

There is no single best hero. Play the one whose failure mode you find easiest to route around.

Loot, rarity, and six equipment slots

Gravewell has close to 200 hand-authored weapons and armor pieces across six slots: weapon, armor, helmet, boots, ring, and amulet, in four rarities: Common, Rare, Epic, and Legendary. Every piece has a fixed stat line and a band of floors it can drop on, so the pool you are pulling from changes as you go down.

That is why rarity color alone will not tell you what to equip. An item’s power comes from its rarity and the depth it drops at, so a deep Epic can out-scale a Legendary you picked up much shallower. A Gleaming Band pulled from floor 48 genuinely beats the Draconic Ring you were wearing since floor 30. As a rough rule, an Epic needs to be about 45% deeper than the Legendary to overtake it.

Beyond that, read the stat line against your build. A Legendary stacking crit damage does nothing for a hero with no crit rate to trigger it.

Nothing carries between runs. All of it is gone when you die, which is what makes the mid-run upgrade decisions matter.

Passives are where builds happen

Before you descend, the start screen rolls you one passive out of 16. You can reroll it as many times as you like until you get one you want to play, and whatever you take in is yours for the whole run. One passive, no swapping, no stacking.

That single choice is the closest thing Gravewell has to a build order, because it decides what the rest of the run is trying to support. A few examples of what is in the pool:

  • Executioner: enemies below 35% health take 65% more damage.
  • Reckless Edge: +30% attack, but your maximum health is cut by 20%.
  • Rising Tempo: every attack you land raises attack speed by 8%, stacking five times per battle.
  • Last Stand: once per battle, a fatal blow leaves you at 25% health instead of killing you.
  • Bloodletter: attacks deal bonus damage based on the enemy’s current health, which is how you handle bosses with huge health pools.
  • Scavenger: makes equipment drops far more common.
  • Retribution: reflects the full damage you take back at your attacker.

Levelling up is the other half. Your hero gains levels mid-run, and each one offers three stat bonuses to choose between: attack, health, defense, speed, crit, lifesteal, gold, or experience. They are small on their own and decisive in aggregate, because they are the only lever you have for pointing a run at what your passive is already good at. An Executioner run wants the crit and attack rolls. A Regrowth run wants health, so there is more pool to regenerate.

The passive you rolled plus the bonuses you feed it is the build. Reroll for a passive you actually want to play, then take the stats that serve it rather than the biggest number on offer.

Bosses actually do things

Dungeon bosses in Gravewell are not just enemies with bigger numbers. Each one can carry an ability on top of its stat line:

Enrage, Lifedrain, Shield, Burst, Regenerate, and Poison.

That is why a boss costs roughly four times what a regular fight costs you. A regenerating boss punishes a build that cannot kill quickly, and a bursting one punishes a build with no health to spare. Since your passive is locked in at the start, the answer has to come from the gear you equip and the level up bonuses you bank on the way down.

Every death buys permanent progress

Gravewell is a roguelite, not a roguelike, and the difference is Relic Shards.

You earn shards for every floor you clear, and you keep them when you die. A run that ends badly on floor 30 still pays for itself. Back at camp you spend those shards on permanent upgrades that apply to every future descent:

Vitality, Strength, Fortitude, Swiftness, Precision, Ferocity, Sanguine, Avarice, Erudition, and Keen Mind (which grants extra rerolls on level up choices).

The result is that failure is never wasted. You come back from every death a little more dangerous, and floors that used to end runs stop being a problem.

99 floors, 20 biomes, then endless

The handcrafted dungeon runs 99 floors deep across 20 gothic biomes, roughly five floors each, in this order: the Catacombs, Fungal Depths, Frozen Gate, Sunless Warrens, Spider Nest, Molten Vault, Drowned Halls, Bone Cathedral, Shifting Maze, Ashen Wastes, Serpent Pit, Obsidian Spire, Void Gallery, Infernal Gate, Frozen Abyss, Chaos Rift, Demon Throne, Celestial Breach, Pandemonium, and finally The Last Descent.

Nearly 600 enemies fill those floors, and each biome has its own pool, so the dungeon genuinely changes character as you go down rather than recoloring the same skeleton.

Past floor 99, the dungeon does not stop. It keeps scaling, compounding enemy power every floor, and the only question left is how deep you can push before it catches you.

Six tips for descending deeper

  1. Health is your real resource. Gold, gear, and levels all replenish. Health barely does. Route around damage when the map lets you.
  2. Buy the merchant heal. New players spend all their gold on gear and arrive at the boss half dead. A heal is often the better item.
  3. Reroll for the passive you want. Rerolls at the start screen are free and unlimited, and the passive is locked for the whole run. Then feed it: picking the highest number every level up gives you a hero that is mediocre at everything.
  4. Attack speed is damage. In an auto-battler your damage is what you hit for multiplied by how often you swing, so a 20% speed increase is worth about what a 20% attack increase is. New players undervalue it.
  5. Skip elites when you are hurt. They hit half again as hard as the pool around them, which is a fine trade at full health and a bad one on the way to a boss.
  6. Read gear stats, not rarity color. Depth counts as much as rarity, so a deep Epic can beat a Legendary you have been carrying for ten floors.

Frequently asked questions

Is Gravewell free? Yes, the whole game is playable free and ad supported. The first few floors of every run are ad free; past that, descending to the next floor plays a short ad, and an occasional one runs between fights. There is one optional purchase that removes every ad permanently. It buys no stats, no currency, and no shortcuts, so there is nothing to fall behind on: no energy timers and no pay-to-win.

Do I have to keep watching? No. Battles resolve on their own, so it works as a genuine idle RPG. You come back for the choices.

Is there an end? There is a final floor at the bottom of the handcrafted dungeon, and then an endless descent past it for anyone who gets there.

How long is a run? Short enough for a commute, and long enough that a deep one feels earned.

Start your descent

Gravewell is for anyone who likes roguelites, idle RPGs, dungeon crawlers, and loot-driven hero builds, and wants all of that in a game they can play one handed. Build a hero, take the well one floor at a time, and turn every death into the run after it.
