Hunter's Mark (Class Ability)

You choose a creature you can see within range and mystically mark it as your quarry. Until the mark ends, you deal an extra 1d6 damage to the target whenever you hit it with a weapon attack, and you have advantage on any Wisdom (Perception) or Wisdom (Survival) check you make to find it. 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.

You can maintain the mark for a number of hours equal to half your ranger level (rounded down). The mark then ends unless you expend another use of this feature.

You can use this feature twice. You regain expended uses when you finish a short or long rest.
