Arcane Evolution Remastered

I'm confused by the terminology of how this L4 Sorcerer feat is written in the remaster.

Your arcane legacy allows you to perceive how magic affects everything. You become trained in one skill of your choice. Additionally, you can use arcane arts to tinker with your selection of spells. During your daily preparations, you can choose one spell in your spell repertoire to be a signature spell that day. You can use the Learn a Spell activity to add more arcane spells to the list you choose from, but if you prepare a spell that isn’t in your repertoire, you temporarily add it to your repertoire at the spell rank of your choice instead of making it a signature spell.

Reading carefully through this, I see three benefits. The third is the one I'm not parsing well.

The terminology in three doesn't seem to match the class. "You can use the Learn a Spell activity to add more arcane spells to the list you choose from..." Sorcerers don't have a list they choose from. They have a repertoire. What does this mean?

Then it continues, "...but if you prepare a spell that isn't in your repertoire, you temporarily add it to your repertoire..." Sorcerers don't prepare spells. What is it referring to? How long is temporarily?

Are people interpreting benefit 3 not to be a separate benefit but further explanation of benefit 2? So instead of getting a free signature spell from your repertoire, you could pick another spell from the arcane list as a non-signature spell? If so, why is it written this way? When it says you can add more "arcane spells" (plural), does that mean it's not limited to one? Learn a Spell says it takes one hour per spell rank to learn, and you must pay the price on the Learning a Spell table. Does that mean if you want to add a 5th level spell to your repertoire, you have to spend 5 hours during your daily preparation and pay 70gp and then it's only temporarily added until your next daily preparation?

I would appreciate hearing folks' opinions on how they're parsing this, thanks!

Pre-master, this feat granted the sorcerer a spellbook which contains their entire spell repertoire and to which they could add spells using Learn a Spell. They could then choose one spell in the spellbook during their daily preparations - if it is already in their repertoire, it becomes a signature spell for that day, and if it isn't, it gets added to the repertoire for the day.

Remaster has the same effects, except they do away with the spellbook. The wording is somewhat awkward. You should be able to find the old version on Archive of Nethys under Legacy content - that may help you understand the intent better.

So basically you use Learn A Spell to add spells to the list of spells you can choose to add to your repertoire each morning, or you can instead pick a spell you already have in your repertoire and gain it as a signature spell.

The wording is a little awkward, but essentially it's just saying that you need to Learn a Spell to be able to pick it as your daily bonus spell for Arcane Evolution, rather than just being able to freely pick any spell from the tradition.

The old wording was functional and concise. I don't understand why they changed it, nor why they removed the spellbook. Is there some D&D connection that would have prompted it?

Wow. That is pretty messy. I would have interpreted it as a third benefit (in that you get both a signature spell and a non-repetoire spell) had it not been for the very last sentence.

Even then it's not clear that it is adding a whole "secondary spell list" mechanic.

Welcome to the Remastered not being proof read before release. Not that I blame Paizo for it, they are/were under a ton of stress but they really could use someone to help read stuff.

I got a little further and found another issue tied to Arcane Evolution.

Greater Physical Evolution, L12 Sorcerer feat
Prerequisites Arcane Evolution or Primal Evolution

You change form readily. Once per day, you can use a sorcerer
spell slot to cast any common polymorph battle form spell of the
spell slot’s rank as if it were a signature spell in your repertoire.
You can use the extra spell slot from either Arcane Evolution or
Primal Evolution instead of a sorcerer spell slot.

So far as I can interpret, there's no extra spell slot from Arcane Evolution. How is this supposed to work for an arcane sorcerer?

An arcane sorcerer would just use their regular spell slots.

Reading it the same. You can either use your extra slot (Primal) or any of your normal slots. For arcane, that would mean extra spells known and not much more. Extra spells known is not too bad, and as they're also signature spells it's actually quite good.

Dragon Form for the win.
