Each oracle draws upon a divine mystery to grant her spells and powers. This mystery also grants additional class skills and other special abilities. This mystery can represent a devotion to one ideal, prayers to deities that support the concept, or a natural calling to champion a cause. For example, an oracle with the waves mystery might have been born at sea and found a natural calling to worship the gods of the oceans, rivers, and lakes, be they benign or malevolent. Regardless of its source, the mystery manifests in a number of ways as the oracle gains levels. An oracle must pick one mystery upon taking her first level of oracle. Once made, this choice cannot be changed.
At 2nd level, and every two levels thereafter, an oracle learns an additional spell derived from her mystery. These spells are in addition to the number of spells given on Table: Oracle Spells Known. They cannot be exchanged for different spells at higher levels.
Each oracle must choose from among the following mysteries. Unless otherwise noted, the DC to save against these revelations is equal to 10 + 1/2 the oracle’s level + the oracle’s Charisma modifier.
