So, RAW, focus spells cannot be quickened. However, cantrips also can't be lower-ranked than your highest spell slot, yet they can be quickened.

Cross posting from PF2E forum, in case there is a PFS-specific ruling on this.

The text of the 10th level Oracle class feat 'Quickened Casting' says....

If your next action is to cast an oracle cantrip or an oracle spell that is at least 2 ranks lower than your highest-rank oracle spell slot, reduce the number of actions to cast it by 1 (minimum 1 action).

Focus spells are not mentioned. Does this mean focus spells cannot be quickened, or are focus spells implied to be included as a sort of cantrip?
