If the Unseelie disciple gains sneak attack from any other source (such as rogue levels), add these levels together when determining the strength of their sneak attack (thus, a rogue 1/Unseelie Adept 1 would possess 1d6 sneak attack, not 2d6).
This replaces shadowstuff and shadowmark.
Rogue Talents: At 6th, 12th, and 18th level, the Unseelie Adept gains a rogue talent of his choice, treating his fey adept levels as rogue levels when determining their effects. At 12th level, the Unseelie disciple can choose advanced talents in place of rogue talents.
This replaces create reality, improved create reality, and greater create reality.
