In this game, appearance and bio actually matter and aren't just there for RP. A bio established the resources and skill someone starts with and appearance will be used to identify particular vampires or mages. "That MG has a red, pulsating aura! I've heard of an MG that looks like her - she's known for being heaps powerful! I'd better not attack her."
A vampire starts off with double the stats of a normal human but a mages can triple their stats by entering into their magical form. The exception to this is mana which is quadrupled, though any stat gains to mana go to the magical form. How stats are going to be gained is the tricky bit.
For mages, every vampire they kill gives the mage 2 mana points. The other stats are gained through mundane means though I'm not sure how Will can be gained. Maybe I just shouldn't have it as a stat?
It gets a lot more tricky for vampires. First of all, a certain amount of people need to have their souls devoured before the vampire can get a stat point. These stat points can be spent on increasing any stat, and are in fact the only way to do so. The issue here is buying stats vs powers. Should stats and powers cost the same? Should stats cost more? Should some powers be worth more than others? Then there's the worth of a mage's soul. It should always be worth at least 1 stat point, but should it be worth more than that? 3, perhaps?
As for the vampires, I've decided on using modified Hellsing vampires.
Whenever a vampire drinks a person's blood they're consuming their soul.
Drinking from a virgin of the opposite sex will turn them into a vampire, otherwise they become a ghoul.
Piercing a vampire's heart, decapitating them, or destroying most of their brain with a silver weapon will kill them.
Mundane weapons are pretty much harmless.
Crossing a moving body of water is fatal unless using a bridge or vessel.
Daylight kills.
Hunger weakens a vampire and may send them into a berserk state if left unchecked for too long.
A wooden weapon through the heart won't kill a vampire, but it will weaken them greatly.
Blessed weapons have no effect, just so I don't have to pick what religion is right or wrong.
A vampire killed by a mage will have their soul consumed by the mage.
Aside from silver weapons, a vampire can be killed by a mage's power or even their bare hands so long as the same methods are used (destroy the heart/cut off the head/blow up the brain).
