Rudimentary Prayers and Arcane Spell casting

Not official but I vaguely remember an official answer from way back, so I may be hallucinating or the prevailing sentiment of the powers that be might have changed.

(I’m assuming you mean in ARG)

Unless something has changed, yes, you can, by both RAW and intent (representing the most, pardon the pun, rudimentary of training. It’s a limited level of mastery that requires an intense amount of time, training, and resources to accomplish, learning that singular cant or Arcane spell (tying up a talent for 1 such ability). You’re still precluded from taking the Spell Mastery as usual.

Dean,

I would let whoever it is know that the official errata hasn’t caught up yet, but that the intent (per Henry) is that the answer would be no. That’s an accurate reflection of reality.

With a sweep of his hat,

I can tell you with firm confidence that the current party line is: the only Arcanum source that mixes with another is Psionics. All other groups are non-miscible. The rationale for this is that the mindset needed to manipulate the Arcanum means that to access it one way, your brain just is not wired to deal with it another way. Psionics is ever the strange one because it is a biological capacity of vals.

However, you are correct that in the Rules as Written, it IS possible to gain Rudimentary XXX Talent when you have a non-miscible XXX Spellcasting Talent. There is no restriction in the book as written, and nothing (yet) in the Errata or Campaign Guide. This will have to be corrected in the next rewrite of those documents, at least the Campaign Guide to reflect this.
