Amulets

*Betwixt Amulet*: Oliver’s original amulet made from Celestial jade and Infernal silver. Has no special properties besides sentimental and symbolic value. Was at one point badly damaged in battle against Lilith, but has since been repaired.
*Holy Flame*: An amulet meant to replicate the original, though made entirely of Celestial materials, gold and ruby. Has a very warm feeling to it, though this made it somewhat uncomfortable for Oliver to wear for extended periods.
*Royal Pendant*: Mortal jewelry made of polished Celestial amethyst and sapphire. It was used as a symbol of divinely-ordained rulers, though the family line this initially belonged to lost favor with Heaven, leading to the blessing and amulet to be rescinded. Oliver was allowed to keep it.
*Heart of Brimstone*: Infernal pendant made of sulphur. Shines brightly at all times, yet has an unpleasant smell to it, and mortals are incapable of being in its presence for too long.
*Infernal Pendant*: pendant made from a polished block of ice from the frozen lake of Cocytus, with an insert containing magma from the infamous Lake of Fire. Even mortals with no spiritual strengths can sense the dark essence of this pendant. This was given to Oliver as a gift by [REDACTED] to enhance his latent Infernal strengths against potential threats. Can cause debilitating corruption to mortals, so Oliver does not allow this to be used by them.
*Essence of Creation*: Forged for Oliver to parallel the Infernal Pendant. Powerful enough for mortals not trained in the spiritual realms to sense its light. Until he reached his full potential, this also amplified his latent Celestial strengths. Creation was authorized by Cerberus, with the stipulation that mortals never use it, otherwise its power could overwhelm their bodies.

Fun fact, both Heart of Brimstone and Essence of Creation use alchemical symbols; the former using one of the symbols for sulphur, the other of which was seen in the comic with The Forgotten, and the latter using the symbol of, well, creation.
