Chi Casting allows the Abjurer to draw upon his chi to cast a spell faster. By doing so, he loses 1 EP per round saved. It is used automatically when spells are cast. Each round of casting time is checked up to half the casting time. If a successful check is made that round is removed and casting time reduced. Thus a person with 100% chi casting will have 1/2 casting time as they will succeed each time check up to half. A person with 50% chi casting will succeed only half the checks on average and result in a 1/4 reduction in casting time. Chi Casting only works on spiritual abjuration, air, earth, water and physical spells (representing four of the five elements: air, earth, water, and metal — the fifth, tree, is covered by the nature category and the nature entreaty skill).
