I have a few nits to pick.
Circle of Star druid
The option to swap Starry Forms isn't always available when intended. It's not that it's on cooldown or lost in radial menus, it isn't even available to assign to a slot.
The alternative version of Guiding Bolt that consumes Starry Maps instead of spell slots appears to be either incomplete or is actually pointless as it can't be upcast and is locked at level 1, wgile the regular version(which is unlocked at the same time) does not have. Functionally, it's a bonus Guiding Bolt at low levels and a limited use cantrip at higher levels.
Arcane Archer fighter
"Battle Master, but half the arrows never work even when they hit."
The save DC on arcane arrows would be better if they all used the same ability score. At the moment, the save DC is based on the same ability it targets, so you will inevitably get some arcane arrows which are utterly pointless because they will almost always fail against almost all targets. This is the IGMISS problem all over again basically, except arcane arrows use 5 out of 6 ability scores so it's even worse!
This is in contrast to casters, which normally use only a single ability score to apply the same effects with a spell(unless it's IGMISS as a racial bonus or you multiclass to another caster class).
To put it another way:
Arcane Arrow A pits the user's Strength against the target's Strength.
Arcane Arrow B pits the users Wisdom against the target's Wisdom.
All of a non-multiclass wizard's spell have SSDC based on the user's Intelligence, pitted against the stat listed for the spell.
If the intent for Arcane Archer is increase build variety, that's...fine I guess? But the result of leaving it the way it currently is will be everyone thinks "what if Battle Master bad."
