When a Large or larger creature within 5 feet of you hits or misses you with an attack, you can use your reaction to attack that creature immediately after its attack, provided that you can see the creature.
Beginning at 3rd level, you can use your action and expend one ranger spell slot to focus your awareness on the region around you. For 1 minute per level of the spell slot you expend, you can sense whether the following types of creatures are present within 1 mile of you (or within up to 6 miles if you are in your favored terrain): aberrations, celestials, dragons, elementals, fey, fiends, and undead. This feature doesn't reveal the creatures' location or number.
When you engage in two-weapon fighting, you can add your ability modifier to the damage of the second attack.
While traveling for an hour or more in your favored terrain, you gain the following benefits:
Difficult terrain doesn't slow your group's travel.
Your group can't become lost except by magical means.
Even when you are engaged in another activity while traveling (such as foraging, navigating, or tracking), you remain alert to danger.
If you are traveling alone, you can move stealthily at a normal pace.
When you forage, you find twice as much food as you normally would.
While tracking other creatures, you also learn their exact number, their sizes, and how long ago they passed through the area.
You have advantage on Wisdom (Survival) checks to track your favored enemies, as well as on Intelligence checks to recall information about them.
