Hexblade's Curse interaction with Hex

I was looking at the Arcane Subclass UA latest version of the Hexblade Patron.

The Hexblade's Curse says: 

Your patron grants you the power to curse and hinder your foes. As a Bonus Action, choose one creature you can see within 30 feet of yourself. The target is cursed for 1 minute, during which you gain the benefits below. The curse ends early if you use this feature again, if you dismiss it (no action required), or die. You can use this feature a number of times equal to your Charisma modifier (minimum of once), and you regain all expended uses when you finish a Long Rest. When you cast a spell using a spell slot that curses a target, you can use your Hexblade’s Curse as a part of casting that spell instead of taking a Bonus Action. When you do so, the target of the spell is the target of your Hexblade’s Curse, and your Hexblade’s Curse’s duration is either 1 minute or the spell’s duration, whichever is longer.

So it seems you can use Hex and Hexblade curse at the same time. But what happen when you kill your target and you use a bonus action to curse a new creature?

HEX:

If the target drops to 0 Hit Points before this spell ends, you can take a Bonus Action on a later turn to curse a new creature.

Does this line "the target of the spell is the target of your Hexblade’s Curse" indicate that the Hexblade curse transfers with the Hex to the new target?

Also what spells are counted as "curses"? Bestow Curse obviously, but what about debuff spells like Bane or Blindness/Deafness or Tasha's Hideous Laughter? 

The Rules Glossary definition on "Curses" seems to be saying that it's only a curse if it actually uses the word "curse", so things like Hex and Bestow Curse count, but things like Bane or Blindness/Deafness don't.

As for whether you can move Hex and Hexblade's Curse at the same time when the target dies, that would make a lot of sense and it's probably how I'd rule it, though I think the wording is annoyingly vague there and it could go either way.

Yeah, without this interpretation a warlock, after killing the first cursed victim would have to either:

- spend 2 bonus actions to 1. move Hex AND 2. inflict Hexblade's Curse to a new character, or

- spend a new pact slot and cast Hex again plus a new use of Hexblade's Curse in a single bonus action, thus completely negating the advantage of Hex, which is that it can be transferred without spending ulterior spell slots. :/

which is silly and impractical. 

HOWEVER there is also this line: 

You can use this feature a number of times equal to your Charisma modifier (minimum of once), and you regain all expended uses when you finish a Long Rest.

And piggybacking on Hex (which lasts at least 1 h) would kinda of sneak around this usage per long rest limitation right?

I mean, it might be intended to be used this way, as that if you piggyback on Hex you are still spending a precious pact slot, while if you are using Hexblade Curse alone you are not. 

The key thing you're missing is the "When you cast a spell" part. Relocating Hex is not casting it.

What I was thinking is that that when you cast Hex the target of the Hexblade's curse = target of the Hex. 

So my though process (which might be wrong, of course) was: when the target of the Hex changes later on (during the course of the same spell) so does the one of the Hexblade Curse, because they are identical.

The fact that there's no language in Hexblade's Curse itself about transferring the curse to a new target would make me rule against this as a DM

You can piggyback on Hex on the initial casting because Hexblade's Curse specifically says you can. It would need additional specific language to allow a transfer

You do also get a benefit already when the target drops to 0 hp

Hungering Hex. When the target cursed by your Hexblade’s Curse drops to 0 Hit Points, you regain Hit Points equal to 1d8 plus your Charisma modifier.

 Gosh, I really hope they add it.

Xanarhar's hexblade curse was once per rest, lasted up to a minute without concentration, and could not be transfered to a new.target if first one died.

It seemed intended to be for nova damage against the boss bbeg. If you can transfer it and if you can keep.recasting it several.times, the power output of a warlock just got a LOT of buffing.

And warlocks.are already super buffed and the most popular 2 level dip to get that buff. Everyone wants eldritch blast and agonizing blast. One more level and you can do a curse to stack even more damage???

Id hope this gets rejected as OP.

Warlocks already do more damage thant any ranged martial of the same level and all you need is a 2 level dip. Then multiclass to paladin for melee smite or sorcerer for tons of spell slots and powerful spells, and you've completely outpaced what a fighter or ranger could do with a bow.

 As it is right now in UA, though, the Curse does not inflict extra damage at all, at least until lev14. 

While I think the language of the ability is needlessly vague (especially considering there are two total spells that "curse" opponents, so they could just put clarifying language in for Hex), there's enough clarity for a ruling. Specifically, "the target of the spell is the target of your Hexblade’s Curse." When you kill the initial target of your Hex, you can spend a Bonus Action to change your target, so the new target of the spell is the new target of the Hexblade's Curse. Now, if you insist on getting pedantic, you could argue that Hex doesn't use specific language that says it changes the target of the spell, but that's a fight to have in official games where the rules are closely scrutinized. And UA content isn't allowed there anyway.

When they release the Subclass in Ravenloft in June, I hope they clarify it.

Something like:

"the target of the spell is the target of your Hexblade’s Curse that you select at the moment of the casting."

or 

"the target of the spell is the target of your Hexblade’s Curse and in case of Hex you can change it when it perishes, as described by the spell"
