this says a range of 90 feet, other comments say this is just to cast the spell and if the afflicted creature moves outside of that 90 feet as long as the spell is still active then it still works? what if the afflicted casts teleport and teleports to the other side of the globe?  does not make any sense.  even 500 feet of teleport still does not make since through solid stone.  if this works as a beacon of sorts it should have a max range. 

Does Misty Step break concentration on other spells? 

The scenario I'm looking at is if I can use Hunter's Mark on an enemy in one turn, and then Misty Step behind them on the next as a bonus action and use my attack to gain the benefit of the mark. 

Would Misty Step break the concentration used for Hunter's Mark?

First point, obviously, if Hunter's Mark is the only means you have of tracking someone that used a teleport spell, all your tracking checks are going to fail even with advantage.  Although, I must agree, Hunter's Mark probably should have a maximum range for tracking, perhaps a mile or kilometer or kellicam or whatever you want.

Second point, moving the mark from one victim to another is not what the spell says.  "If the target drops to 0 hit points before this spell ends, you can use a bonus action on a subsequent turn of yours to mark a new creature."  It says you may mark a new victim, therefore that new victim must again be within the initial range of 90 feet of the ranger.

This spell doesn't make sense to me

"You choose a creature you can see within range and mystically mark it as your quarry" ATTACK/SAVE None Does this mean you can cast this undetected? If not why does it last 1 - 24 hours with a range/area of 90 ft. Doesn't the spell dissipate after the target leaves 90 ft? Why would you have advantage on any Wisdom (Perception) or Wisdom (Survival) check you make to find it it it's only 90 ft area.

 It means you don't need an attack roll, and the target doesn't get a saving throw. They would still be able to hear the verbal components of the spell being cast, if they have the ability to hear.

Both any kind of weapon attack but not for spells.

Does the attacker know if they've killed a target while hunter's mark is on them? What if the target is a troll, it dies, and then regenerates? Would they know right away that the troll is alive if the mark is still on them??

I would say that is up to the DM as it doesn't say anything about knowing if the creature is alive once you mark as the mark seemingly stays on once it is dropped to 0hps. 

I can't find anything that says that it doesn't use concentration...are you talking about the spell or about Favored Foe? Cause favored for specifically says it lasts "1 minute or until you loose concentration" did they change this somewhere or can you Hunters Mark a Favored Foe now?

A ranger in the party cast Hunter's Mark on a ghost... which then went ethereal, And then cam back into the material plane. Was the Hunter's Mark broken while the ghost was ethereal? Was it back on when it returned to the MP?

Does the target sense that it has been marked when it is casted or no?  Looking for your opinions please!

I wouldn't think so. You could always play it so the target has to make some sort of saving throw (like perception, insight, survival, or just straight wisdom).

 

 The spell has a verbal component. I'd use common sense here (You're hidden, 60 feet away and whispering with ambient background noise? It doesn't hear you). Pairing this with the Subtle Spell metamagic would make it nearly undetectable outside an active detect magic spell, though such a situation would be highly unlikely.

lmao the url to this doesn't have an apostrophe. That's funni

Detect Magic might pick it up.

As a DM, I may tell the marked character that they have a 'uneasy feeling' that someone is watching them. Hah :-)

No

If you are a ranger with two shortswords and use dual weapon fighting, does "hit it with a weapon attack" mean I get to apply it twice for this attack action or only once per attack action?

 Once per hit.

What is its casting time

 Bonus Action.

Does it cost another spell slot to move it to another target?

 

 No.

 Hunter's Mark will not help track down the bbeg if he teleports arcoss a planet, but a creature that runs away or an enemy going into stealth can be found easier. If you fine where someone teleported to, you could track them from there.

 The mark was not broken. The ranger probably could not track the ghost in the Ethereal plane.
