Ghost Walker

You are a ranger of the shadows. You might trace your lineage to an entity from the Shadowfell, or perhaps you were exposed to its fell energy and transformed by it.

The power of the shadows casts a strange pall over your physical presence. The spark of life that sustains you is muffled, as if it struggles to remain viable against the dark energy that imbues your soul. At your option, you can pick from or roll on the Shadow Quirks table to create a quirk for your character.

Shadow Quirks

Ghostly shape

You can enter a Ghostly Shape causing your body to become blurred, shifting and wavering to others. For the duration, any creature has disadvantage on attack rolls against you. 

An attacker is immune to this effect if it doesn't rely on sight, as with blindsight, or can see through illusions, as with truesight.

On your turn, you can enter a Ghostly Shape as a bonus action, and it lasts for 1 minute. It ends early if you are knocked unconscious.

You can enter Ghostly Shape twice and you regain expended uses when you finish a short or long rest.

You can also end Ghostly Shape as a bonus action. 

Spirit Blade

At 3rd level, you learn to cloak the weapon you are wielding in flame-like shadows. The weapon deals an extra 1d4 necrotic damage on a hit.

Fright

Your eyes become an inky void imbued with dread power. You awaken the sense of mortality in one creature you can see within range.

You can use Fright as a bonus action to target a creature you can see within 30 feet. The target must succeed on a Wisdom saving throw or become frightened of you for 1 minute. The frightened target can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.

You can use Fright a number of times equal to your proficiency modifier, and regain all expended uses on a long rest.

Ghostly Shape - Shadows Cloak

The energy from the Shadowfell have taken a stronger hold on you.

Flame-like shadows wreathe your body, causing you to become heavily obscured to others. The shadows turn dim light within 10 feet of you into darkness, and bright light in the same area to dim light.

While in Ghostly shape you gain blindsight out to a range of 10 feet.

These effects replaces the previous Ghostly Shape's effects.

Gaseous Cloak

While you're in Ghostly shape, you can use a bonus action to envelop yourself in a Gaseous Cloak. Gaseous Cloak lasts until Ghostly Shape ends or until you lose your concentration (as if you were concentrating on a spell).

While in Gaseous Cloak, you have resistance to nonmagical damage, and have advantage on Strength saving throws.

Once you have used Gaseous Cloak, you have to take a long rest before you can use it again.
