Sorcerers in a magic-hostile juncture suffer wounds when they spend Magic.
Sorcerers in a magic-friendly juncture heal wounds when they spend Magic.
Supernatural Creatures in a magic-hostile juncture have -1 Toughness.
Supernatural Creatures in a magic-friendly juncture have +1 Toughness.
The Ghost Archetype has both Sorcery Schticks and Creature Powers. Am I correct in interpreting it that they have all the abilities simultaneously? (So +1 Toughness and Healing with Magic spends when in a magic-friendly juncture?) That seems to be the implication, though I'm not sure the book ever really says so explicitly.
