The arcane-archer tag has a quite wrong tag description at the time of this post:
The Arcane Archer is a fighter subclass in Dungeons & Dragons 5th edition (published in Xanathar's Guide to everything), and has the ability to use a number of arcane shots in battle that augment the use of ranged weapons.
However, Arcane Archer predates D&D 5E by years: it had been a prestige class back in the Neverwinter Nights games (which used the 3.5 SRD - where it IS too) and a Pathfinder 1e prestige class from the core book, dating its inception back to about 3rd to 3.5th edition of D&D.
The tidbit about Xanathar's Guide as the first publication of the class is plain wrong; it is not only a subclass, but used to be an independent class in earlier editions... and atop that, the tag is not system-agnostic as it should be, because the term is used across multiple RPG systems.
However, the best I could do is make a different game-centric tag, that focuses on the old prestige class version. So I call for help. (Remember magus? That was a mess we sorted out together.)
As far as I understand them, the arcane archer is basically either a wizard/sorcerer that picked up archery or an archer (ranger, warrior) that picked up arcane magic.
