Infused Shot-better than Colossus Slayer. Nerf.

Archer Magic alone is probably enough for level 3.

Arcane Attunement is good.

Quickened Shot... I'd get rid of the bonus action attack. You're already looking at better single target damage with double tap on Infused Shot, no need to give them better multitarget damage too. (Because, as read, the bonus attack also gains Infused Shot.)

Arcane Shift is good.

My advice? Switch Infused Shot to level 11, and have it apply to only one attack. And don't let them pick more options-every other Ranger only gets one, why do these guys get more?
