The PDF for the Remaster Core Preview is now available. Seems to mainly include stuff relating to things mentioned in Rage of Elements, including the text of several of the new or renamed spells.
There's a new rule on focus points that says "The maximum number of Focus Points in your pool is always equal to the number of focus spells
you know" which seems very significant, though I've seen clarifications elsewhere saying that it's still gonna be capped at 3. The limit on refocusing to just once is gone, though.
Yes, sorry, I was saying that I wish that they had fixed that when they reworked focus points.
Taking random focus spells that you don't need because you had to boost your pool was an issue before the rewrite, and it's arguably even worse now post rewrite, because you benefit by taking them earlier.
Previously you just needed a second focus point by 12 and a third by 18 (since the once-a-day extra points weren't that big a deal). Now if your party has time to rest longer you can get more focus spells per encounter as soon as you can take more spells.
