Gloamwalker

A Rogue trained in the fine art of fey assassination.

Gloom Strike

When you choose this archetype at 3rd level, you learn how to channel the gloom of the Feywild into your strikes. When you land a Sneak Attack on a target, they become surrounded by a 10ft area of dim light. This light darkens natural light and lightens natural darkness, but has no effect on magical light or darkness. While you are in this area of Gloom, you can make sneak attacks against that target without meeting the other requirements for sneak attack, unless the target has blind-sense.

Additionally, you gain darkvision to 60ft.

Halflight Blur

Starting at 3rd level, your connection to the flickering twilight of the Feywild increases your illusiveness. While you are in dim light or darkness, you can use your Cunning Action feature to Dodge.

Additionally, if a melee attack misses you while this feature is active, you can use your reaction to make a melee weapon attack against the offending creature.

Twilit Advance

As a bonus action, you can teleport next to a creature currently emanating Gloom. When you teleport to a creature in this way, the next weapon attack you make against them has advantage.

You can use this feature twice per long rest.

Hidden in Halflight

Starting at 13th level, you can use an action on your turn to become invisible and your footsteps no longer make sound, so long as you are in at least dim light. This invisibility ends if you deal damage to a creature or force one to make a saving throw, otherwise the duration is infinite.

You can use this feature once per long rest.

Gloam Master

Beginning at 17th level, you gain mastery over the gloom of the Feywild, able to open up pockets of it with your blade. You have advantage on attack rolls made against creatures affected by your Gloom Strike. Additionally, creatures who are frightened of you emanate a 5ft sphere of twilight gloom, centered on them. While in this sphere, enemies make all attack rolls and saving throws at disadvantage.
