And one level 1 Spell per day. And one level 2 spell per day once you hit 6th level. And one level 3 spells per day once you hit 8th level. For one Feat. And you get the ability to take more Feats that give you multiple spells per day at appropriate levels. With the only prerequisite being one ability at a score you can easily achieve in up to 3 abilities at first level.
Did I misread the blog? I thought it took another feat to get the level 1-3 spells. I'm looking at it now and it looks like...
Wizard Dedication (INT 16 Req.) == 2 Cantrips per day
Basic Wizard Spellcasting == What you describe.
What don't I understand? What am I missing?
