Gloom Stalker Ranger Guide

You excel at striking before your enemies can react. You have Advantage on attack rolls against creatures that haven't taken a turn yet in the combat. In addition, if you're hidden when you make an attack roll, you deal an extra 1d8 damage with that attack.

You gain oath spells at the ranger levels listed in the Gloom Stalker Spells table. [Gloom Stalker Spells: 3rd - Disguise Self, Invisibility; 5th - Darkness, Pass without Trace; 9th - Fear, Nondetection; 13th - Dimension Door, Greater Invisibility; 17th - Animate Objects, Mislead]

You gain Darkvision within a range of 300 feet. If you already have Darkvision from another source, it increases by 300 feet. You can see in Dim Light within this radius as if it were Bright Light, and in Darkness as if it were Dim Light. You can't discern color in Darkness, only Shades of Gray.

You gain proficiency in Wisdom saves. If you're already proficient in Wisdom saves, you gain proficiency in Intelligence saves instead.

You can use your Bonus Action to make two weapon attacks as part of the Attack action on your turn, rather than one. This increases to three attacks when you reach 11th level.

Starting at 15th level, when a creature within 5 feet of you hits you with an attack while you're in Dim Light or Darkness, you can use your Reaction to impose Disadvantage on the attack roll.
