Ignition

Ignition is the process of two souls forging a special bond together in order to achieve supernatural power. This supernatural power can also be achieved with only one soul, but this requires a powerful soul.

Creatures such as Constructs, Oozes, and Plants don't possess souls. While Outsiders and Undead technically possess a soul, this soul is bound with their body. They still apply for an ignition however.

Those with souls have different types associated with them, granting the character different benefits depending on the type of soul. Souls are influenced by a character's alignment with each alignment coming to a different kind of soul. Souls of opposite corners of the spectrum cannot be combined (Holy Order and Unholy Disorder, Rebel and Swindler).
