Gloom Stalker
Gloom stalkers are at home in the darkest places: deep under the earth, in gloomy alleyways, in primeval forests, and wherever else the light dims. Most folk enter such places with trepidation, but a gloom stalker ventures boldly into the darkness, seeking to ambush threats before they can reach the broader world. Such rangers are often found in the Underdark, but they will go any place where evil lurks in the shadows.
Gloom Stalker Magic
At 3rd level, you gain the following spells. They do not count against your spells known, and count as ranger spells for you. You only gain the spells when you have spell slots for them. The spells are listed by their spell level.
1st Level: Disguise Self
2nd Level: Rope Trick
3rd Level: Fear
4th Level: Greater Invisibility
5th Level: Seeming
Dread Ambusher
At 3rd level, you master the art of the ambush. You can give yourself a bonus to your initiative rolls equal to your Wisdom modifier.
At the start of your first turn of each combat, your walking speed increases by 10 feet, which lasts until the end of that turn. If you take the Attack action on that turn, you can make one additional weapon attack as part of that action. If that attack hits, the target takes an extra 1d8 damage of the weapon's damage type.
Umbral Sight
At 3rd level, you gain darkvision out to a range of 40 feet. If you already have darkvision, its range increases by 20 feet.
You are also adept at evading creatures that rely on darkvision. While in darkness, you are invisible to any creature that relies on darkvision to see you in that darkness.
Iron Mind
By 7th level, you have honed your ability to resist the mind-altering powers of your prey. You gain proficiency in Wisdom saving throws. If you already have this proficiency, you instead gain proficiency in Intelligence or Charisma saving throws (your choice).
Additionally, you gain resistance to psychic damage.
Stalker's Flurry
At 11th level, you learn to attack with such unexpected speed that you can turn a miss into another strike. Once on each of your turns when you miss with a weapon attack, you can make another weapon attack as part of the same action.
Shadowy Dodge
Starting at 15th level, you can dodge in unforeseen ways, with wisps of supernatural shadow around you. Once per round, whenever a creature makes an attack roll against you and doesn't have advantage on the roll, you can impose disadvantage on it.
