When following the Normal sphere point progression, the mystic gains building points equal to double his new level plus his key ability modifier. For example, a mystic wizard with an Intelligence of 17 who achieves fifth level receives 2 * 5 + 3 = 13 additional building points to spend on sphere ranks and Reserve.
When following the Half sphere point progression, the mystic gains building points equal to his new level plus half his key ability modifier (rounded down). For example, a mystic bard with a Charisma of 21 who achieves ninth level receives 9 + (5 / 2) = 9 + 2 = 11 additional building points to spend on sphere ranks and Reserve. Mystic paladins and mystic rangers are treated as three levels lower for the purposes of their mystic magic abilities. For example, a 7th level mystic ranger is treated as a 4th level mystic (with Half sphere point progression).
In addition, mystic wizards receive two bonus Reserve points per level.
