My games use the UA revised ranger (from Unearthed Arcana: The Ranger, Revised) instead of the PHB version of the class. The question did not previously come to mind, because until now my players either chose the Hunter or Beast Master subclasses, both of which have a variant included in the same UA. However, now the question has come up:
Are the ranger archetypes from Xanathar's Guide to Everything compatible with the UA revised ranger base class?
I want to combine the base class from the UA (the part common to all rangers, without subclass features) with a subclass from XGtE, rather than a subclass from the UA. By "compatible", I mean:
- Is it correct that I would need to add Extra Attack to assure that
the class is balanced with other classes? - Are there other differences with a similarly high impact that I
would need to consider?
The reason I suspect they might not be compatible (at least not as written) is the fact that Extra Attack got relegated to the subclasses (except for the Beast Master, which now lacks it). I further assume that the XGtE subclasses were created with the original PHB ranger in mind, which means they would suddenly be seriously downgraded because they lost the Extra Attack feature.
Best Answer
They are not compatible
The Player's Handbook/Basic Rules version of the ranger gets a Ranger Archetype at level 3, while the Unearthed Arcana version of the ranger gets a different class feature called Ranger Conclave. The conclaves that go along with that feature are detailed in Unearthed Arcana: The Ranger, Revised.
Xanathar's Guide to Everything adds new archetypes for the ranger, not new conclaves (page 41):
It is a different class feature for an altogether different class, and they are not compatible.
If you wanted to use one of the archetypes from Xanathar's Guide for the UA ranger, you would first need to create (homebrew) new conclaves that mirror the XGtE archetypes, and worry about balance as part of that process.
Adding extra attack
I am not very experienced in homebrewing and balancing, but the Horizon Walker archetype from Xanathar's Guide to Everything was playtested in Unearthed Arcana: Ranger & Rogue, which includes this text block:
The Monster Slayer archetype was playtested in Unearthed Arcana: A Trio of Subclasses, which contains a similar text block.
So if you are looking to balance these subclasses for use with the UA ranger, that may be a good place to start.
