Is it just me, or is the progression broken?
If you take the Runelord Archetype, you have to take the Runelord Dedication at 2nd level, which means you can't take the 4th level feat Aeon Resonance at 4th level*, because you didn't take Embed Aeon Stone at 2nd level, which means you can't take Aeon Resonance until 6th level, but it's the only dedication feat at 4th level.
What am I missing?
*Demiplane doesn't ever offer Embed Aeon Stone, not even later at 4th level, which is also broken, but that's another issue.
Edit: Nevermind, I see now that it's also a SKILL feat, which has to be taken at 2nd level as well.
