This class was inspired by wanting to make a an arcane focused caster that was also good in melee combat.
The Soul Binder is a full arcane caster with intelligence as your spell casting ability modifier. Your big class feature is a Soul Bound, a humaniod creature that has part of your soul placed within it that is important to all of your class features as well as being a permanent companion. The Soul Binder is themed as being more of a necromancer controlling not only their own soul but the souls of the dead.
Their are three subclasses to choose from: Gold Soul the intellect driven and most logical of the subclasses, Silver Soul the ranged battlefield combatant ruled by passion, and Bronze Soul the hunrgy controlled melee focused subclass
