Necromancy
Necromancy manifests as a combination of powers and actual magic.
Powers
Necromancers are able to absorb ambient life energy unconsciously to speed healing and keep in general health. A downside to this is that, if wounded deeply, the necromancer can lose control of this ability and draw too deeply from a single source, weakening and even killing it.
Necromancers are able to artificially bolster physical abilities(speed, strength, etc) by drawing energy from the world around them. Drawing too much, or too frequently without adequate rest, results in headaches of increasing severity. The headaches will eventually incapacitate the necromancer until the energy deficit is naturally replenished.
Necromancers have a heightened sense of awareness of those around them. He or she can feel recent wounds and painful points on the bodies of those near him. Prolonged contact with the same individual only heightens this awareness, allowing the necromancer to divine the type of life someone has led in reference to physical violence and to identify unknown health conditions.
Magic
Accomplished necromancers can summon and banish beings from beyond the grave and detect living creatures at a distance.
If prepared, the necromancer can cause intense physical pain to an opponent via eye contact or touch, or disconnect the conscious mind from the body, causing the person to lapse into a deep sleep. The latter power cannot be used often on the same person, as there is a chance the individual may not wake up.
He can influence the mind to ignore or heighten sensations of pain or discomfort, and actually drain life from any opponent.
By drawing from his own reserves, the people and other living things around him, a necromancer is capable of healing anything from small cuts and scrapes to potentially fatal wounds. Doing so drains the necromancer and rest is needed after using this power.
Any wound or pain a necromancer purposefully inflicts on another person will eventually be felt as a ghostly echo. This is a backlash for using his powers in such a way.
Divine Magic
Divine magic varies according to the god. In this example, I am using my character Rea. She is a cleric of the god of Law and horses. One thing that hold true is that most, if not all, divine magic must be channeled through a focus; an article of faith that has been blessed by an ordained priest of the faith. In this character;s case, she has two primary foci. The first is a pair of silver bracers she inherited from her grandmother, a former cleric of Law. The second is a silver mace.
Another thing that holds true with all divine magic users is that faith and devotion are directly proportional to power.
Divine magic manifests as a series of powers. These powers are a combination of the user's faith and willpower and the power granted by their god. It is limited by the imagination of the user and the scope of the god's domain(Law, Storms, the Sea, Fire, etc)
By calling on and focusing her faith, Rea channel stunning energy through her focus at the target it comes into contact with. It is more than enough to bring down someone who is unprepared or not protected from such an attack. If allowed time to concentrate, she can direct this power from a distance via her foci. A weaker version of this power can be directed outward from her person at any opponent in the immediate area.
By invoking the name of her deity, Rea can restore things going. Her power can set bones, but not mend them, realign tissues and capillaries, but not seal them, etc. She can restore tampered minds, as long as the damage isn’t too great or the result of something natural(i.e. birth defects)
By focusing her energy, Rea can project a sort of field around her that dispels magical attacks against her person. This is physically draining for Rea, and if she maintains it for too long, the effect is not unlike that of severe intoxication.
The law aspect of Rea’s deity gives her a degree of command over natural phenomena, greatly increasing her destructive capabilities under the right circumstances. For instance, she dictate the path of a fire, if the fire was started naturally, or fix the path of a bolt of lightning in a natural thunderstorm.
Because of her deity, Rea shares a special connection with creatures used as mounts, specifically horses. Such animals take to her easily, and trust her not to harm them. This connection extends not only to her own mount, but also to others'. While she can not actually speak with them, they gain a sort of intuition with her, allowing her to direct them against the will of their owners. Her own horse would enjoy heightened strength and speed, as well as a resistance to injury and an increased rate of healing.
I can give another example of a cleric's powers if this isn't clear enough.
I'm still working out the specifics of sorcery.
