Draconic sorcerers gain the focus spell Dragon Wings at 5th level:
When the spell is heightened to 8th level, "the duration increases to ten minutes."
If a sorcerer has a focus point at time T, and expends it by casting Dragon Wings, then when do they regain that focus point?
From https://2e.aonprd.com/Bloodlines.aspx :
You refill your focus pool during your daily preparations, and you can regain 1 Focus Point by spending 10 minutes using the Refocus activity. Unlike other characters, you don’t need to do anything specific to Refocus, as the power of the blood flowing through your veins naturally replenishes your focus pool.
Does this imply that the sorcerer can’t maintain their wings indefinitely, as (presumably) they would cast the spell in combat, and thus would have some time (e.g. a couple of rounds) where they weren’t engaged in the Refocus activity? I.e. they would start refocusing at some time T + x, where x > 0, and they would only regain the Wings at T + x + 10m ?
I want to say this is correct, but I also like the notion of the sorcerer gaining those wings for as long as they reduce their focus pool by 1, to ‘keep it up’. But I’d appreciate your thoughts.
