Also...forgot to mention...for this, since this thing would become to complicated otherwise...vampires can go out under the sun for a short duration of time, so long as they have a specifically enchanted item imbued with the words 'daywalker'. They can travel under the sun, but they'll lose all vampire magic, powers, and bonuses temporarily...and may feel dry or drained earlier. Once they leave the sun and return to shade or darkness, they forget the specific feeling of having walked under the warm sun, and only remember the generally walking from a) to b).
