Class: Nightmare

One of the players in my just-finished D&D 5e campaign rides a nightmare. In preparation for switching to GLOG, I want to let them play as the nightmare.

from D&D 5e

 

A: Nightmarish, Fiery, Horse That Leaps Over Land And Sea And Sky

B: choose one of Dream Travel or Dimensional Travel

C: Fiery Steed, Trample

D: Fiery Breath and the other Travel ability

Nightmarish

You are a horse, but scary. You cannot speak, but can communicate with those you know well.

You have no hands, but can run really fast (double standard Movement Speed) and count your Strength Might twice for the purposes of Inventory Slots.

Your teeth are razor-sharp and your hooves smoulder - deal d10 damage "unarmed". You can only eat meat.

Fiery

Your mane and tail are on fire. You have fire resistance and shed light as a lantern.

Horse That Leaps Over Land And Sea And Sky

You can walk on water. You can also run on air, but must end each movement action on a solid ground, or fall.

Fiery Steed

You are now immune to fire and may confer fire resistance to one rider.

Trample

You can move through the space of any creature smaller than you and test Might. On success, they are knocked prone and get no attacks of opportunity against you.

You may trample multiple creatures in a single movement, as long as you fail no Might test. On a failed Might test, you lose the rest of your movement.

Fiery Breath

Deal 2d8 fire damage in a 15 feet cone. You can breathe again once you devour a ration's worth of raw flesh.

Dream Travel

Instead of a long rest, you and your rider may dive into the Dreamlands. You can follow the scent of anyone whose blood you have ever tasted and enter their dreaming, if they are currently asleep. Dreamers will remember their interactions with you as strange nightmares.

Sidebar: Willpower (wp) is basically mental hp or sanity, decreased by stress rather than damage. Once you run out of wp, you start freaking out and may gain Vice if you take further stress. I should post the full rules one day.

In a dream, your attacks deal stress rather than damage. If your target is reduced to 0 wp, they wake up covered in cold sweat, their rest forestalled, and gain a Vice of phobia towards you.

Should your dreaming form be reduced to 0 hp or wp, you wake up. This may strand your rider, if they were not riding you at the moment of your return to the waking world.

Dimensional Travel

You can smell dimensional intersections - fey crossings, thin places, inactive portals, etc. Take 1 Fatigue to kick open a rift in such a weak location. It stays open for d6 minutes.

In most of Creation, Twilight is close enough that you can always open a portal there.
