I was wondering how the Shaping Focus Feat works when a Wizard and Druid becomes a Mystic Theurge.
Prerequisites: Wild shape class feature, Knowledge (nature) 5 ranks.
Benefit: If you are a multiclassed druid, your wild shape ability is calculated as though your druid level were four higher, to a maximum level equal to your character level.
Special: This feat has no effect if you are not a multiclassed druid.
So if I have a Wizard 3, Druid 4, and I take 10 levels of Mystic Theurge, do I get Wildshape like a Druid 8, or Druid 17?
Mystic Theurge doesn't advance your wild shape, so you wild shape like an 8th-level druid.
Your Druid level is 4, so you would get wild shape like a Druid 8.
If the Mystic Theurge had an ability that stacked with druid levels for the purpose of wild shape, then you would wild shape as a Druid 17. It doesn't, though; the class only increases spellcasting in this way.
Thanks for the clarification.
