When is it safe to visit Chaos?

The list below tells you which chambers are safe to enter the Chaos gate such that you will not be cursed for the boss fight. It assumes that you will have an encounter every chamber after the Chaos chamber. If you want to be safer, assume that you will have one non-encounter chamber (e.g. Charon's shop, NPC, etc) and adjust the numbers accordingly.

• From Chamber 1-6, enter Chaos Gate and get 5-encounter (or less) curse
  
• From Chamber 7, enter Chaos Gate and get 4-encounter (or less) curse
  
• From Chamber 8, enter Chaos Gate and get 3-encounter Curse
  
• At Chamber 12, safe to get Light of Ixion (spawns Chaos Gate at next opportunity) from Well of Charon.
  
• Chamber 14: Tartarus boss (Furies)
  
• From Chamber 16, enter Chaos Gate and get 5-encounter (or less) curse

Recommended Boons

Stygian Blade

Heart-Seeking Bow

Shield of Chaos

Eternal Spear

Twin Fists

Adamant Rail

Balanced melee weapon with good DPS and area damage

Recommended Boons

• Artemis: passive Attack damage and Special damage increase -- plus criticals -- to multiply the large base damage
  
• Athena: Deflect and Expose for backstab damage
  
• Aphrodite: passive Attack damage and Special damage increase
  
• Avoid Poseidon (for knock-away effects)

Long-range weapon with low DPS

Surprisingly, the bow can be much more effective in short range. The Special can hit an enemy multiples times in close range and deal a large amount of damage.

Recommended Boons

• Ares: reapply Doom with the slower attack speed
  
• Demeter: Chill for easier kiting
  
• Poseidon: Knock-away for more distance/time

Melee weapon with low DPS and the ability to block

Recommended Boons

• Ares: reapply Doom with the slower attack speed
  
• Hermes: movement speed and positioning is important to get the extra collision damage
  
• Poseidon: Knock-away works well with the shield's passive knock-away

Melee weapon with good DPS and range

Recommended Boons

• Artemis: passive Attack damage and Special damage increase -- plus criticals -- to multiply the large base damage
  
• Aphrodite: passive Attack damage and Special damage increase; can spread Weak easily with Spin Attack
  
• Dionysus: can spread Hangover easily

Risky close-quarters melee weapon with high DPS

Recommended Boons

• Hermes: movement speed and positioning is important due to the short range
  
• Athena: Deflect and Expose for backstab damage
  
• Zeus: lightning from rapid attack speed and dashes
  
• Avoid Poseidon (for knock-away effects)

Medium-range weapon with good DPS and area damage, and is more difficult to use

You may want to disable aim assist with the rail.

Recommended Boons

• Zeus: lightning from rapid attack speed
  
• Demeter: quick stacks of Chill and for easier kiting
  
• Dionysus: quick stacks of Hangover
  
• Avoid Poseidon (for knock-away effects)

Keepsakes provide a passive buff for Zagreus while equipped. One keepsake can be equipped at a time. You can equip a keepsake in the weapons room. Your currently equipped keepsake is shown in the Boon Info overlay, last boon in the left column. The Keepsake Collection work order (at the House Contractor) allows you to switch keepsakes between Underworld regions.

Recommendations

• Old Spike Collar from Cerberus: Increase maximum health
  
• Chthonic Coin Purse from Hypnos: Instantly receive Obol. Since there is no passive benefit, swap to another keepsake at the next opportunity.
  
• Lucky Tooth from Skelly: Revive after taking fatal damage (once per escape attempt). This activates only if there are no more Death/Stubborn Defiances.
  
• Broken Spearpoint from Patroclus: Gain temporary invulnerability after taking damage.

Shadow Presence: Bonus damage to enemies from behind
Fiery Presence: Bonus damage to undamaged enemies

Recommendation: Shadow Presence

Chthonic Vitality: Restore 3 health per chamber
Dark Regeneration: Upon collecting Darkness, also restore health by 60% of the Darkness

Recommendation: Dark Regeneration is triggered by collecting Darkness from chamber rewards, from Charon's shop/well, from Infernal Troves, and from Sisyphus. A large amount of Darkness is dropped from bosses if you have already defeated them once before. Dark Regeneration is a good choice for beginners especially if you are collecting a lot of Darkness to upgrade your abilities.

Dark Regeneration has almost no benefits in Styx because Darkness is only available in Well of Charon here. Once you can comfortably reach Styx, you may want to switch to Chthonic Vitality.

Death Defiance: Revives you with 50% health (3 chances)
Stubborn Defiance: Revives you with 30% health (1 chance per chamber)

Recommendation: Death Defiance offers much more survivability. It's important to note that Death Defiances can be replenished from Well of Charon (replenish 1 Death Defiance for 200 Obol), from some of Athena's boons, and from Patroclus (replenish all used Death Defiances).

Greater Reflex: Extra dash
Ruthless Reflex: Bonus damage and dodge if you dash before getting hit

Recommendation: The extra dash from Greater Reflex allows for more mobility and more safety. Midway through a dash, you can cancel into another dash. This is very helpful when you mistakenly dash into incoming enemy attacks.

Boiling Blood: Bonus damage to enemies with bloodstone (Cast ammo) attached
Abyssal Blood: Reduces speed and damage of enemies with bloodstone (Cast ammo) attached

Recommendation: Boiling Blood

Infernal Soul: Extra bloodstones (Cast ammo)
Stygian Soul: Bloodstones (Cast ammo) instead regenerate over time

Recommendation: Stygian Soul offers more consistent usage of Cast and is in general easier to use.

Deep Pockets: Start with 100 Obols
Golden Touch: Gain 15% of your Obols when you exit a region

Recommendation: Once you find yourself exiting a region with 500 Obols or more, Golden Touch will provide significantly more wealth than Deep Pockets.

Thick Skin: +50 maximum health
High Confidence: +25% damage when above 80% health

Recommendation: Thick Skin

Privileged Status: +40% damage to enemies with at least 2 status curses
Family Favorite: +5% damage for each unique Olympian whose boons you have

Recommendation: Privileged Status. It is not too difficult to apply two status curses. See notes below. Also, Family Favorite discourages you from getting higher tier boons.

• Boon Tiers: Some boons enhance others and won't appear until you have the prerequisite(s). For example, Aphrodite's Broken Resolve enhances the Weak status curse and this won't appear unless you already have a boon that applies Weak. There are 3 tiers.
  
• Status Curses: Each god (except Hermes) offers boons that can apply a status curse. Some of the status curses are available at Tier 1 and some at Tier 2.

Best Status Curses for Privileged Status

Some of the status curses are more accessible than others, and some are easier to maintain on enemies than others.

1. Chill (Demeter, Tier 1, 8s duration)
   
2. Hangover (Dionysus, Tier 1, 4s duration)
   
3. Weak (Aphrodite, Tier 1, 3s duration)
   
4. Exposed (Athena, Tier 2, 5s duration)
   
5. Doom (Ares, Tier 1, 1s duration, duration does not refresh, see note below)
   
6. Jolt (Zeus, Tier 2, 10s duration, expires when enemy attacks, see note below)
   
7. Ruptured (Poseidon, Tier 2, 3s duration)
   
8. Marked (Artemis, Tier 2, 2.5s duration, expires when enemy takes critical damage)

• When the conditions are met, the enemy is marked with a Punished icon next to their health bar.
  
• Attacks, Specials, and Casts inflict damage before they apply any status curses. For example, when an enemy is inflicted with only Hangover and then is hit with a Cast that applies Weak, the Cast's damage comes first and is not increased due to Privileged Status.
  
• Doom technically deals damage before its status curse ends. This means that the enemy only needs to be inflicted with one other status curse in order for Doom to benefit from Privileged Status.
  
• Jolt deals damage after its status curse ends. This means that the enemy needs to be inflicted with two other status curses in order for Jolt to benefit from Privileged Status.
  
• Marked needs to be confirmed.

Olympian Favor: +40% chance for Rare boons
Dark Foresight: +10% chance for God Boon, Daedalus Hammer, and Pom of Power chambers

God's Pride: +20% chance for Epic boons
God's Legacy: +10% chance for Legendary or Duo boons

Fated Authority: Gain dice to alter the reward for the selected chamber
Fated Persuasion: Gain dice to alter the Boon and Well of Charon choices

• 1 dice is needed to alter a chamber, and only that one chamber is altered.
  
• Gain 1 dice from Chthonic Key chambers.
  
• There are three types of chambers. A chamber can be altered only to another of its type.

Types of Chambers

• Blue laurel (Gemstones, Darkness, Chthonic Key, Nectar)
  
• Gold laurel (Obol, Pom of Power, Centaur Heart, Daedalus Hammer, God Boon)
  
• Unalterable (Charon's Shop, NPC, Boss)

• 1 dice is needed to alter a set of choices the first time, another 2 dice for the second successive alter, another 3 dice for the third successive alter, and so forth.
  
• Gain 1 dice from Chthonic Key chambers.

• Fishing: Instead of looking directly at the fishing spot, look above it and keep it in your peripheral vision. It will be easier to see the flash.
  
• God Mode: God mode grants 20% damage reduction plus 2% per failed escape attempt (i.e. damage reduction increases the more you fail). Turn on God Mode if you ever feel like the game is too difficult. You can enable and disable this at any time in Settings. There are no penalties for enabling or disabling this, and this has no impact on the story events. All achievements and all items in the Fated List can be unlocked with God Mode enabled.
  
• Focusing on Particular Gods: The gods that you have are more likely to appear later in the run than gods that you don't have. It's a valid strategy to avoid getting boons from particular gods (or purging boons) to increase the chances of getting boons from the gods that you want.
  
• Bosses: Boss chambers appear at fixed numbers and the chamber immediately before will not have any enemies. The Boon Info overlay displays the current chamber number.
  

  Boss Chambers

  • Chamber 1: Tartarus
    
  • Chamber 13: no enemies
    
  • Chamber 14: Tartarus boss (Furies)
    
  • Chamber 16: Asphodel
    
  • Chamber 23: no enemies
    
  • Chamber 24: Asphodel boss (Hydra)
    
  • Chamber 26: Elysium
    
  • Chamber 35: no enemies
