Bind Spirit: A seal-bound sorcerer may seal pacts with otherworldly entities known as spirits. In order to summon a spirit, the seal-bound sorcerer must learn the spirit’s ceremony, constellation, personality, and seal by completing its four Knowledge Tasks; see Researching the Spirit for more information on this process. A soul-bound sorcerer begins play having completed all four Knowledge Tasks for one 1st-level spirit of her choice that belongs to her chosen constellation (see tunneled lore below).
Each day, a seal-bound sorcerer may bind one spirit to her soul using pact magic; see Performing a Pact Ritual. This spirit’s level may not exceed the seal-bound sorcerer’s maximum spirit level, which is limited to 1st-level spirits at 1st level. At 4th level and every three sorcerer levels thereafter, the seal-bound sorcerer maximum spirit level increases by 1, to a maximum of 6th-level spirits at 16th level.
A seal-bound sorcerer’s binder level is equal to her level. The DC to resist a seal-bound sorcerer’s supernatural powers is equal to 10 + 1/2 the seal-bound sorcerer’s binder level + the seal-bound sorcerer’s Charisma modifier.
This ability replaces the sorcerer’s bloodline spells.
Diminished Spellcasting: A seal-bound sorcerer has one fewer spell known at each level (including cantrips) than is presented on Table: Sorcerer Spells Known in the Pathfinder Roleplaying Game Core Rulebook.
Tunneled Lore: At 1st level, a seal-bound sorcerer chooses one constellation. She may only seal pacts with starless spirits and spirits belonging to her chosen constellation. All other constellations are barred to her.
