Spells: Spelltouched creatures can casted spells as a wizard, cleric, or druid as a 17th level caster plus their own class levels. Each level they choose one of the three ways, giving them a veriaty of spells to cast.
Spelltouched creatures are still members of their own race, except that their mother had a powerful epic spell casted on her while still in the womb and had the magic linger. They naturally see in the dark from the magic, and can naturally see magic. These creatues are not to be taken lightly, unless they play tricks which some seem to enjoy.
