“ When a miracle is worked, when a God turns His attention to the mortal realm, the mortal realm is irrevocably changed by the Divine Presence. When this takes place through a living being, they become the Godmarked. Ever with one foot in life, and one foot in the realm beyond, they are emotionally and physically altered - always in a fashion that reflects the nature of the God that they have channeled - One who channels a God of the Winds may forever have a breeze lifting their hair, while a Goddess of Anger may blacken the skin and strengthen the body.”
“ Swords form a bond to their wielder. A symbol on the grip that is absorbed through the user's hand and appears on the back of the hand. Maybe only visible to them or others that have the abilities. Could give unique powers depending on when it happened and what they did to get it. It takes a specially made sword that only few can receive and made by a certain race. Then they must do something really heroic to unleash the swords power. Once unleashed it is theirs till they die then the sword goes dormant again till another accomplishes another feat.”
“ Expansion from the Horse Brass item: Specific Armor charms.
Cooling Touch Charm: protects horse against extreme heat, and fire, magical and mundane
Jove's Favor: tin charm shaped by a lightning bolt that protects a horse primarily from natural lightning, but also potentially from lightning based attacks. In real life, lightning kills quite a few horses and cattle a year.
Hermes' Blessing: gold charm that grants the horse magic resistance, and perhaps immunity to cantrip level magics.
Vulcan's Steed: This large iron charm in epic fashion renders the steed invulnerable to iron weapons. Such things clatter off of the animal's hide like twigs.”
