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?

Do the Illusionist’s Bracers with the War Caster feat let you take a bonus action on somebody else’s turn? [duplicate]

So basically this answer states:

[…] The War Caster feat says:

When a hostile creature’s movement provokes an opportunity attack from you, you can use your reaction to cast a spell at the creature, rather than making an opportunity attack. The spell must have a casting time of 1 action and must target only that creature.

The current text of Illusionist’s Bracers says:

While wearing the bracers, whenever you cast a cantrip, you can use a bonus action on the same turn to cast that cantrip a second time. […]

[…] So read Illusionist’s Bracers again, and it sure looks like this:

  1. On a creature’s turn, the creature provokes an opportunity attack from a war caster with Illusionist’s Bracers.
  2. The war caster casts a cantrip at the creature as a reaction.
  3. The Illusionist’s Bracers grants a bonus action to the war caster that can be used on that same turn.
  4. The war caster casts the cantrip again with that bonus action, not on the war caster’s turn. […]

Really my question is simply whether or not this is correct. If something would let you take a bonus action when it is not your turn, can you take that bonus action?

Can you use a Bonus Action on a turn other than your own?

The rules for Bonus Actions (PHB, pg.189) state;

You can take only one bonus action on your turn…

Which to me can be read in two ways.

  1. You can only take a bonus action if it is your turn.
  2. You can take only one bonus action on your turn but can take one or more on someone else’s turn.

As an example, if I were to ready an attack action could I also use a bonus action for Two-Weapon Fighting when the trigger is met?

Does a UA Dhampir Cleric Turn Itself? What does that look like?

Dhampir have two types tags in the new Unearth Arcana, they are both humanoid and undead. There is even a nice rules reminder in D&D Beyond that points out:

If an effect works on at least one of a creature’s types, that effect can work on that creature. For example, if you are both a Humanoid and an Undead, cure wounds works on you, since the spell works on a Humanoid.

Everything so far is peachy keen. I was going to introduce an NPC that is a Dhampir Cleric, but ran across an odd edge case. If the cleric uses Channel Divinity: Turn Undead I’m not sure what happens:

Channel Divinity: Turn Undead As an action, you present your holy symbol and speak a prayer censuring the undead. Each undead that can see or hear you within 30 feet of you must make a WIS saving throw (DC 14). If the creature fails its saving throw, it is turned for 1 minute or until it takes any damage. A turned creature must spend its turns trying to move as far away from you as it can, and it can’t willingly move to a space within 30 feet of you. It also can’t take reactions. For its action, it can use only the Dash action or try to escape from an effect that prevents it from moving. If there’s nowhere to move, the creature can use the Dodge action.

I know it is play test material and will have weird edge cases like this not hammered out. I also know at my table I will have to make a call if it comes up. However, as it stands, the NPC is an undead within 30 feet who can see and hear itself, so RAW would have to make the roll, right? And what would it mean if you failed it and became turned and had to move away from itself? What would that look like?

Is it possible to turn a monster into a humanoid without giving them average physical ability scores?

Savage Species lists some rituals through which a creature can–in one example given–transform from an ogre into an elf.

If nothing else, it’s an interesting and evocative idea: a 6th level ogre barbarian who tires of racial prejudices and transforms into an elf. His RHD disappear, and he becomes a 6th-level elf barbarian. His lower effective level means he can no longer travel with ECL ~12 parties, but he decides to do it anyway. Heck, maybe he did it partly because he was tired of that +2 LA that Savage Species likes to pretend isn’t a big deal.

Unfortunately, losing all those hit dice is far from the worst thing that happens to him. Doing any of the book’s major rituals means his physical ability scores become, at best, 11/13/9. Considering his ogre-born mental scores aren’t picking up much slack either, this is pretty much unacceptable for a barbarian in all but either very silly or very gritty games.

Is there any printed way around this, or to compensate for this beyond things like wishing for inherent bonuses and equipping magic items (which any high level barbarian is going to get anyway, so the transformed elf barbarian still finishes with noticeably poor scores)?

Can a Wildshaped Druid trigger Dive Attack twice in a turn?

So I have a lizardfolk moon druid and I was curious about the interaction between his bonus action Hungry Jaws ability and the Dive Attack ability of the Quetzalcoatlus.

"Dive Attack. If the quetzalcoatlus is flying and dives at least 30 feet toward a target and then hits with a bite attack, the attack deals an extra 10 (3d6) damage to the target."

"Hungry Jaws. In battle, you can throw yourself into a vicious feeding frenzy. As a bonus action, you can make a special attack with your bite. If the attack hits, it deals its normal damage, and you gain temporary hit points (minimum of 1) equal to your Constitution modifier, and you can’t use this trait again until you finish a short or long rest."

Now if I Dive Attack I can use my action to bite and receive the Dive Attack bonus damage.

My question is if I also use my bonus action Hungry Jaws to bite does it also benefit from the Dive Attack bonus damage?
