Mikasa Extra Sheet+Free Or Non Actions+Mind over Matter

When using the forbidden lore class feature, the knight of willpower is particularly powerful with certain spheres at the cost of others. When using forbidden lore to strengthen an effect from the Creation, Light, or Telekinesis sphere, the increase to his caster level is 50% higher than normal. This increase does not affect the bonus granted by invocations. When using forbidden lore to strengthen the effect of any of the other spheres, the increase to his caster level is only 50% of the normal value.

A knight of willpower may push themselves beyond their normal limits and apply this bonus to any sphere, eliminating the usual penalty to those spheres (or apply it a second time to the Creation, Light, or Telekinesis spheres for a total of a 100% increase to those spheres), by increasing the chance of backlash to 30% and increasing the penalty to attack rolls, saving throws, skill checks, and their effective caster level to -2. When used in this way, his forbidden lore bonus for the purposes of invocations is treated as if it were 50% higher. When using forbidden lore in this way the chance of backlash occurring cannot be reduced by any means.

This modifies forbidden lore.
