Student of Thassilon - retraining possible?

[PeteZero]

I just received a boon that lets me create a Thassilonian Specialist.

With the boon, could I also retrain to Student of Thassilon as I have a 1st lvl sorcerer / 2nd lvl wizard?

and spoiler gone

Pete, if you read this before an hour has passed would you mind your post to say something like:

"I just received

Spoiler:

a boon that lets me create a Thassilonian Specialist."

instead of naming the scenario? (Or just omit the spoiler altogether.)

To answer your question: Thassilonian Specialist is NOT an archetype, it's a very specialized school. However Ultimate Campaign does allow Wizards to retain their school.

Quote:

You can instead retrain your arcane school (including changing to or from a universalist). Doing so replaces your school’s bonus spell slots and school powers. This training takes 5 days for every school power you lose from changing schools.

So most likely it would take you 10 days, cost 10 prestige and 3x10x10=300gp. And you must own Ultimate Campaign.

edit: There is a line in the Thassalonian Specialist description that says something like "This choice must be made at 1st level, and once made, it cannot be changed." This doesn't apply to retraining (the same language appeared in the core rulebook for a base wizard's school.)

Also, there's a more direct reason this is a no.

Thing in Question:

Through the study of Krune’s sanctum and personal effects, Pathfinder sages have deciphered many of the secrets of Thassilonian magic and howto avoid the sinful excesses that twisted Xin’s magic. When building a new character for Pathfinder Society Organized Play, you may make use of the Thassilonian magic rules on
page 17 of Pathfinder Campaign Setting: Inner Sea Magic. As with other rules outside the core assumption, you must provide a legal copy of the book to use this option. (Emphasis mine)

From the explicit wording, I'm fairly sure you can't use it to retrain. Sorry.

I think this has been asked before and Mike said that it only applied to new characters. On phone, so quote finding is not that quick.
