Does Ranger Monster Hunter’s Slayer’s Counter works on saves to maintain concentration?

From the Sage Advice Compendium:

Does a Monster Slayer ranger’s Supernatural Defense feature apply if a creature damages the ranger, thus causing the ranger to make a Constitution saving throw to maintain concentration on a spell? Yes.

Since the Supernatural defense works for concentration, does the Slayer Counters works as well?

Did the UA “revised” Beastmaster Ranger make it into any official source book?

There was "The Ranger, Revised" pdf in the 2016 playtest material. A Beastmaster Ranger was considered the weakest class by many GMs and players, which apparently caused the need for a "revised" version.

However, I’ve never heard how exactly the playtesting ended. Googling "ranger revised" gives me the same 2016 pdf and nothing more.

What happened to the "revised" ranger from the Unearthed Arcana? Was it renamed from "revised" to something else? Was it published in any official source book, changed or unchanged? (I don’t have access to all of them so I can’t check it myself for now) Or was it abandoned by WoTC?

This is probably a duplicate of this question, which was answered in 2017, but things could change in 2021.

Can you use the Ranger Slayer’s Prey Twice a turn? [duplicate]

From Xanathars:

Slayer’s Prey Starting at 3rd level, you can focus your ire on one foe, increasing the harm you inflict on it. As a bonus action, you designate one creature you can see within 60 feet of you as the target of this feature. The first time each turn that you hit that target with a weapon attack, it takes an extra 1d6 damage from the weapon.

It says you that the first time each turn that you hit THAT target you deal 1d6, so, that being said, can you:

Turn 1: Mark a creature with Slayer Prey Turn 2: Hit the creature with Slayer Prey, gaining the 1d6 bonus damage, design another creature with Slayers Prey and gain the 1d6 bonus damage again?

My thoughts are: You are hiting the secord creature for the first time in this turn, so this should work, right?

How to build a psionic Ranger?

I would like to build a 13th level NPC Ranger-type, i.e. nature and stealth themed warrior, with psionics instead of spellcasting. Are there

a) guidelines to adept spellcasters to psionics b) existing Alternative class features or Ranger variants allowing for psionics c) feats that would allow fullscale psionics (i.e. more than wild talent) d) prestige classes that would allow an effective combination of ranger class features and psionics in 13th level?

Losing spellcasting is not mandatory, though preferred to a build that merely adds psionics to a ranger for roleplaying reasons.

Ranger Beast Master’s attack bonus

The Ranger companion says to add your proficiency bonus to the animals attack roll. Does this replace the animals proficiency bonus or add to it?

Ie does a 5th level ranger flying snake get +9 bonus or +7? The snakes natural +6 is it’s +4 dex bonus and it’s +2 proficiency bonus so does the ranger replace the +2 with her +3 bonus or add her +3 to the +6?

The players hand book says not to add your proficiency more than once which might suggest the +7 but technically the snakes proficiency and your proficiency are not the same bonus which would suggest the +9.

What is the duration of the resistance effect of Swarming Dispersal for a Swarmkeeper Ranger?

In the Ranger section of Tasha’s Cauldron of Everything appears a new version of the sub-class Swarmkeeper, which is quite distinct from the UA version.

There is a new ability called Swarming Dispersal (TCoE, p.60). The feature does have an effect for which no duration is specified:

Swarming Dispersal

15th-level Swarmkeeper feature

You discorporate into your swarm, avoiding danger. When you take damage, you can use your reaction to give yourself resistance to that damage.

You vanish into your swarm and then teleport to an unoccupide space that you can see withing 30 feet of you, where you reappear with the swarm.

You can use this feature a number of times equal to your proficiency bonus, and you regainall expended uses when you finish a long rest.

Is this an instantaneous effect, does it last until your next turn, or does it have another duration?

I’m looking for a RAW answer, potentially including comparison with examples of similar features in other classes.

How does the Mobile feat interact with the Writhing Tide for a Swarmkeeper Ranger?

In the Swarmkeeper section for Rangers in Tasha’s Cauldron of Everything there is an ability called Writing Tide (TCoE, p.60), which allows the Ranger to fly.

Writhing Tide

7th-level Swarmkeeper feature

You can condense part of your swarm into a focused mass that lifts you up. As a bonus action, you gain a flying speed of 10 feet and can hover. The effect lasts for 1 minute.

You can use this feature a number of times equal to your proficiency bonus, and you regainall expended uses when you finish a long rest.

In the Player’s Handbook the feat Mobile (PHB, p.168).

You are exceptionally speedy and agile. You gain the following benefits:

• Your speed increases by 10 feet.

• When you use the Dash action, difficult terrain doesn’t cost you extra movement on that turn.

• When you make a melee attack against a creature, you don’t provoke opportunity attacks from that creature for the rest o f the turn, whether you hit or not.

Does this mean that if you take Mobile as a feat, the benefit would apply to this particular feature too – effectively having a fly movement of 20 feet instead?

Does the Ranger’s Companion synergize with the Ranger?

The Ranger Beast Master subclass gets an animal companion under the ranger companion ability, which for free can move about the battle field, or using the Ranger’s action can make an attack. Being a cr 1/4 creature, that attack is generally worse than the attack the ranger has by the time he gets the companion.

If the ranger was multiclassed a rogue, I could see the use of the companion moving about to be adjacent to enemies, but I’m not seeing what synergizes well without multiclassing.

Am I missing something, or should I tell my friend that his assessment is correct, and he should only choose the beast master if he wishes the fun of his animal companion but that the creature itself will not actually synergize very well with his class abilities?

I prefer a rules as written answer.

Are XGtE subclasses compatible with the UA ranger

My games use the UA ranger instead of the PHB variant. The question did not previously come to mind, because until now my players either chose hunter or beast master, both of which have their variant in the UA. Now the question did come up:

Are the XGtE ranger archetypes compatible with the base ranger class from unearthed arcana?

The reason I suspect it might not (at least not as written) is the fact that extra attack got relegated to the subclasses (except for the beast master who now lacks it). I further assume that the XGtE subclasses where created with the original PHB ranger in mind which means they would suddenly be seriously downgraded because they lost the extra attack.

By compatible I mean:

  1. Is it correct that I would need to add extra attack to assure that the class is balanced with other classes?

  2. Are there other differences with a similar high impact that I would need to consider?

Clarification: I want to combine the base class (the part without the subclass which is common to all rangers) from the UA with a subclass from XGtE rather than one which is also from the UA.
