In order to face his father's armies across the Underworld, Zagreus must equip himself properly. Among his arsenal in Hades, the Prince of the Underworld possesses the Adamantine Cannon and its various aspects. This gun can be unlocked with Chthonian Keys once the spear, bow and shield are unlocked and offers a long-range style of play.
After unlocking the 6 basic weapons, the different aspects of each of them can be obtained. You have to spend a certain amount of Titan Blood to unlock them, but each aspect offers unique bonuses and skills.
Appearance of Zagreus
This is the base form of the weapon, available for 8 Chthonian Keys. Taking advantage of a great distance but also of a Bombing raid with its technique, the Canon Adamantin does not leave much room for mobility.
Passive: Magazine capacity
Attack: Fires a bullet, can fire continuously until the magazine is empty or Reload
Technical: Target an area to bombard
Assault: Dash forward and shoot the nearest target

Aspect of Lucifer
To unlock the hidden aspect of Lucifer, you must first have obtained the hidden aspect of the Eternal Spear and spent a total of 5 Titan's Blood in upgrading the Adamantine Cannon. As soon as these conditions are met, you must regularly discuss with Zeus until he offers you the aspect. You can force its appearance at the start of an evasion with the Lightning Signet Ring. In this form, the Adamantine Cannon exchanges its Bombing raid against the Igneus Eden. A ball of energy then appears at the targeted location, inflicting regular damage to nearby enemies, and capable of exploding as soon as it receives damage from the cannon.

Attack: Fires a laser, can fire continuously until the magazine is empty or Reload
