Adamant Rail

Exagryph, the Adamant Rail, is an Infernal Arm that can be unlocked for 8 Chthonic Keys after all other weapons have been unlocked. It is a ranged weapon modeled after a repeating rifle.

Fighting style
The Adamant Rail's primary attack fires bullets rapidly out of an ammo cache in the direction Zagreus is looking. These bullets do not stagger enemies or cause them to flinch, and they deal low damage. Zagreus is immobile while firing.

When the Rail is out of ammo, it must be reloaded. It will reload automatically when out of ammo, or a manual reload can be triggered with the "Reload" action.

The Rail's special attack is "Bombard". Using it targets an area around the cursor and launches a large grenade at it. After a brief delay, the grenade will hit the targeted area, dealing massive damage to enemies within the blast zone. The grenade will bounce back from walls and obstacles.

Aspects
The Adamant Rail has 4 Aspects: Zagreus, Eris, Hestia, and Lucifer. Like all other weapons, each Aspect has 5 levels that can be unlocked by spending Titan Blood. The higher the level of the Aspect, the more effective its improvement is. Reaching the highest level in all Aspects requires 51 Titan Blood. An Aspect will not only change the appearance of the Adamant Rail, but will also improve its attacks. The Aspect of Lucifer has a unique move-set which changes the fighting style of the Adamant Rail. * See below for Igneus Eden's alternate moveset.

Revealing the Aspect of Lucifer
Reveal the Aspect of Lucifer by meeting the following requirements:
 * Reveal the Aspect of Guan Yu (does not need to be unlocked with Titan Blood)
 * Have a total of 5 or more invested into Rail aspects
 * Talk to Zeus (with any weapon equipped) until he gives you the waking-phrase ("I see your prideful fall down from the heavens to the flames")
 * Equip the Rail at the House and then interact with its placeholder to reveal the Aspect of Lucifer

Upgrades
These are all the upgrades the Adamant Rail can receive when using the Daedalus Hammer. Some upgrades are mutually exclusive, and cannot be combined with each other.

Daedalus Hammer upgrades for the Rail can either change its "Fire" (Attack) pattern, add new effects to the Rail's bullets, or change its "Bombard" (Special) attack pattern.
