In Hades, the door symbols shown before each chamber tell you exactly what kind of reward you will earn for clearing that room. Each icon corresponds to a specific boon, item, or resource, and knowing what they mean is key to planning a successful run.
The Core Door Symbols and Their Meanings
Every door in the Underworld displays a small icon. Here is what each one represents:
- God Boons (colored circle with a symbol) – A colored icon with a unique emblem indicates a boon from a specific Olympian god. For example, a red circle with a spear is Ares, a blue trident is Poseidon, and a yellow lightning bolt is Zeus. The color and symbol always match the god.
- Heart (pink/red heart) – Gives you +1 HP, permanently increasing your maximum health for the rest of the run.
- Centaur Heart (green heart) – Grants a larger boost to your max HP, usually +25, but the exact amount can vary.
- Obol (gold coin) – Gives you a set amount of Charon’s Obol, the currency used to buy items from Charon’s shop.
- Gemstone (purple diamond) – Awards a number of Chthonic Keys, which are used to unlock new weapons and abilities at the House of Hades.
- Darkness (purple droplet) – Provides a batch of Darkness, a resource used for the Mirror of Night upgrades.
- Chthonic Key (gold key) – Gives you a Chthonic Key, which unlocks new weapons and upgrades in the House.
- Diamond (blue diamond) – Awards a Diamond, a rare resource used for the House Contractor’s renovations and certain weapon aspects.
- Ambrosia (golden bottle) – Grants a bottle of Ambrosia, a rare gift for character bonds and certain quests.
- Titan Blood (red blood drop) – Gives you Titan Blood, a rare resource used to unlock and upgrade weapon aspects.
- Boon of the Fates (three spinning fates) – Offers a choice of one of three random boons from different gods, letting you pick the one you prefer.
- Hammer (blacksmith hammer) – Grants a Daedalus Hammer, which upgrades your current weapon with a special mod (e.g., faster attack, more damage, or a new move).
- Pom (purple/pink flower) – Gives a Pom Blossom, which levels up one of your existing boons by one rank.
- Shop (gold bag with a coin) – Opens a Charon’s Shop where you can spend Obol on items, boons, or healing.
- Fountain (blue fountain) – Restores a portion of your health and sometimes gives a small bonus.
- Boss door (skull or large icon) – Indicates a boss fight. These doors are usually at the end of a region and are marked with a large, unique icon.
Some doors also show a small skull icon next to the reward, meaning the chamber has a mini-boss (like a stronger enemy) that you must defeat to get the reward.
How Door Symbols Change the Run
Your choice of door directly affects your build. For example, if you are playing with the Shield of Chaos and want to focus on blocking, you might prioritize doors with Ares or Athena boons. If you need more health for a tough boss, pick a Centaur Heart. The game also randomizes which doors appear, so you must adapt your strategy on the fly.
In the first region (Tartarus), you usually see two doors after each chamber. In later regions (Asphodel, Elysium, and the Temple of Styx), the choices become more complex, with some doors leading to different paths or offering a choice between two rewards.
How to Choose the Right Door
There is no single “best” door, but experienced players follow a few general rules:
- Prioritize boons early – In the first few chambers, grab boons from gods that complement your weapon or playstyle. A good boon can carry you through the entire run.
- Take hammers for weapon builds – If you have a specific weapon aspect in mind, a Daedalus Hammer can be more valuable than a boon.
- Balance resources – If you are low on health, a Centaur Heart or Fountain is better than a boon. If you are saving for a shop item, grab Obol.
- Think about the endgame – For the final boss, you need a mix of damage, defense, and healing. Don’t ignore health upgrades.
Common Misconceptions
One common mistake is confusing the Heart (max HP) with a heal. The heart icon does not restore your current health; it only raises your maximum HP. Your current HP stays the same, so if you are at 10/50 and take a heart, you become 10/60. To heal, you need a Fountain, a shop item, or a boon that restores health.
Another misconception is that the purple droplet (Darkness) is the same as the purple gemstone (Chthonic Key). They are different resources: Darkness upgrades the Mirror of Night, while Chthonic Keys unlock new weapons and abilities.
Frequently Asked Questions
What does the skull icon next to a door mean?
A small skull next to a reward icon means the chamber contains a mini-boss, such as a stronger version of a regular enemy or a special foe like the Wretched Sneak. Defeating it gives you the same reward as a normal chamber, but the fight is harder.
Can I skip a door and go back?
No. Once you choose a door and enter the chamber, you cannot go back. The door closes behind you, and you must clear the room to proceed. So choose carefully.
Are some door rewards rarer than others?
Yes. Titan Blood, Diamonds, and Ambrosia are rare and usually appear only in specific locations or after certain conditions (e.g., after you have unlocked certain aspects or completed prophecies). They are not common rewards.
Does the door symbol ever lie?
No. The icon always matches the reward you will get, except for the “Boon of the Fates” door, which gives you a choice of three boons. The shop door also shows a bag of Obol, but you still need to spend Obol to buy items.
How do I get more Titan Blood?
Titan Blood is primarily obtained from boss fights, especially the Furies, the Bone Hydra, and Theseus and the Minotaur. You also get it from certain prophecies and from trading with the Wretched Broker at the House of Hades.
Why Door Symbols Matter for Builds
Your door choices determine your boon synergy. For example, if you have the Aspect of Zagreus on the Twin Fists, you might want boons that boost your special or dash attacks. If you are using the Adamant Rail, you might want Zeus’s boon for chain lightning on your attack. Knowing which god’s symbol matches your desired build helps you pick the right doors.
Also, some gods have boons that work better in certain regions. For instance, Poseidon’s boons that push enemies are great in Asphodel because you can knock them into lava. Ares’s Doom effects are strong against single targets, while Dionysus’s Hangover is good for sustained damage.
Resource Doors vs. Boon Doors
In the early game, you may want to prioritize resource doors (Keys, Darkness, Gems) to unlock new weapons and upgrades. In the late game, boons become more important because they directly affect your combat power. A balanced approach is usually best: take resource doors when you are missing a specific unlock, and boon doors when you need to strengthen your build.
Remember that some resources, like Chthonic Keys, are also used to unlock the Fated List of Minor Prophecies, which gives you rewards for completing specific tasks. So even if you have all weapons, keys can still be useful.
Final Tips
- Always check the door before entering – the icon is your only clue.
- If you are unsure, choose the door that gives a boon from a god you like using.
- Don’t ignore the shop – sometimes buying a healing item or a rare boon is better than a random door reward.
- For the final boss, make sure you have at least 100 max HP and a good damage source.
Understanding door symbols is one of the first steps to mastering Hades. Once you know what each icon means, you can plan your run, adapt to the random choices, and make it to the surface more often.
