Every Infernal Arm can clear the game and push high Heat with the right Aspect and boons — but some are far more forgiving. This ranks them for general use, with the Aspect that pushes each to the top.
The six weapons ranked
Pick by playstyle
- Want safety? Varatha (Guan Yu) or the Aegis shield block-and-rush.
- Want ranged control? Coronacht (Rama) or Exagryph keep you out of danger.
- Want aggression and speed? Malphon fists reward dodging into the fight.
- Learning high Heat? Aspect of Arthur's aura and bonus max health carry newer players.
How the weapons and Aspects unlock
- The Stygian Blade is yours from the start; the other five are bought from the Arsenal with Chthonic Keys, earned from room-clear rewards and trades: Coronacht 1, Aegis 3, Varatha 4, Malphon 8 and Exagryph 8, 24 in total. Exagryph comes last, once every other weapon is yours.
- Aspects stay locked until all six weapons are yours. From there, Titan Blood spent at the weapon itself unlocks and upgrades them: about 5 Titan Blood maxes a weapon's first new Aspect, and each further Aspect runs closer to 15.
- Each weapon's fourth, hidden Aspect unlocks later still, and it starts with the Spear's Aspect of Guan Yu: you need the Fated List of Minor Prophecies bought, to have reached the final boss at least once — reaching, not beating — and Titan Blood already spent on Aspects. How much is where the guides part: Game Voyagers asks for at least 5 Titan Blood, Games Learning Society for five Aspects other than Zagreus's across your weapons, and RPG Site for three Aspects unlocked. Achilles then gives the pass-phrase. The other five each need Guan Yu unlocked, 5 Titan Blood invested in that weapon's own Aspects, and a pass-phrase from a specific character — Nyx for the Sword, Chaos for the Shield, Artemis for the Bow, Asterius for the Fists, Zeus for the Rail; you cannot enter it yourself.
Best boon pairing per weapon
- Spear (Guan Yu): attack boons and lifesteal — Ares Doom or Zeus on attack.
- Bow (Rama): Artemis crit and Hunter's Mark make marked Power Shots devastating.
- Shield (Zeus): Zeus lightning on the Blitz-disc special for constant chain damage.
- Fists (Malphon): fast on-hit effects like Aphrodite Weak or Zeus Jolted shine with the attack speed.
