The Pathfinder 2 developers were in a Twitch stream, where they confirmed some errata for the core rules. Thanks to @Markh3rd for the scoop!
The developers said they will be releasing official critical errata soon as well as monster creation rules (so we will have them before the GameMastery Guide comes out).
- Humans are supposed to have one more language (Common + Bonus + INT).
- Your proficiency in simple weapons is also what your proficiency in unarmed should be, including the wizard. Monk is an exception as they are better at unarmed.
- Ki spells cue off Wisdom for the monk.
- Sorcerer is missing a 17th level Resolve class feature, just the same as the wizard's (includes master will save, critical success, etc.).
- Wizards don't get a 1st level class feat by default. This was a mistake. They only get one for being a universalist.
- The adventurer's pack is only 1 bulk.
- Heroic Recovery takes you to 0 hit points, not 1.
