Can my Druid in Dungeon World, through use of the Hunters Brother move and Stalkers Sister move, take the following two Ranger moves: Animal Companion and Special Trick. We are accepting as a given that I can take Animal Companion. The real question is: can I use the Ranger's Special Trick move to gain access to the Wizard's Cast a Spell move?
Druid move: Hunter's Brother "choose one move from the Ranger class list"
Druid move: Stalker's Sister "choose one move from the Ranger class list"
Ranger move: Animal Companion <grants Animal Companion>
Ranger move: Special Trick "choose a move from another class. So long as you are working with your animal companion you have access to that move"
I'm inclined to say yes, because other moves that allow multi-class moves specifically exclude further multi-classing. For example:
Barbarian move Appetite for Destruction says "Take a move from the Fighter, Bard, or Thief class list. You may not take multiclass moves from those classes."
In other words, they considered that further multi-classing is possible, and they specifically forbade it for the Barbarian using his multi-class move. They specifically did NOT forbid it for the Druid using his multi-class rule.
Therefore I think it is allowed (if they didn't want it, they would have expressly said so, as they did with Barbarian). I'm not sure WHY they would draw that distinction between the two different multi-class moves, but the game designers DID draw that distinction.
My GM and I are working together to see what is overall best for our table, but we are seeking clarification (especially any "official" clarification), and also looking to avoid potential pitfalls or troubles. Any helpful input is appreciated.
P.S. - I believe it is already established that gaining a starting move from another class also grants you any other starting class moves from that class which are necessary to make the move useful, such as Prepare Spells and Spellbook.
