Spiritual Punishment

Sacred Puishment is different from lover level punishments (Forced and Nimble) in the fact that its bottom boost treshold rises with levels iinstead of staying 11. So instead of having the 11-15, 11-20, 11-25, 11-30, 11-40 progression, it goes up-up-and-awwaaay : 11-15, 16-21, 21-27,31-35, 41-45. By boosting that, you'll get heaps of Int through only 3-5 hits. Your fire damages go skyhigh. Fire damages? See Absorption.

This punishment is essential for the use of Absorption later on, Absorption being the only spell that brings you back life while dishing out damage.
