I have a question about the Advanced Rogue Talent 'Familiar'. It gives a Rogue 'a familiar as the Familiar option of the Wizard's arcane bond class feature.' Can a Rogue take this talent, but then instead of getting the Arcane Bond class feature, take one of the replacement options? Such as Siege Engine Bond or Arcane Gun?
No. It doesn't give you the Wizard's arcane bond class feature; it gives you the Familiar option. If they'd meant the rogue to have all the options of the arcane bond class feature, they would have said that.
