Favored Foe (Optional Ranger feature alternative)

Starting at 1st level, you gain the ability to mystically mark someone as your favored foe. As a bonus action, choose one creature you can see within 90 feet of you. The mark lasts for 1 minute. The mark ends early if you die, or you are incapacitated. Until the mark ends, you gain the following benefits:

• You deal an extra 1d4 damage to the marked target whenever you hit it with a weapon attack
• You have advantage on any Wisdom (Perception) or Wisdom (Survival) checks you make to find the last marked target for a number of hours equal to 4 times your proficiency bonus.
• When the marked creature dies, you can use a bonus action to mark a different creature you can see within 90 feet of you, provided you aren’t incapacitated.
• A target marked with this feature can not be targeted by you with a hunter's mark spell.

This feature's extra damage increases when you reach certain levels in this class: 1d6 at 5th level, 1d8 at 9th level, 1d10 at 13th level and 1d12 at 17th level. 
You can use this feature to mark a favored foe a number of times equal to your proficiency bonus, and you regain all expended uses when you finish a long rest.
