Prehaps your a scavenger living off the remains of the destroyed empire of Cyre, or some one born to the edges of the mournlands, or a descendant of some one who survived the "mourning" but you are called to these lands, and know them as well as anyone can. Forever altered by the magics, knowing the signs of the dead-grey mists, the wasteland striders are able to make what amounts to a living out here. 

Living Spell Magic

Starting at 3rd level, you learn an additional spell when you reach certain levels in this class, as shown in the Mournland Strider Spells table. The spell counts as a ranger spell for you, but it doesn’t count against the number of ranger spells you know.

Horizon Walker Spells

Wasteland Survivor

At 3rd level, you gain the ability to find ways to survive the mournlands, and gain profiency in the survival skills in the mournlands, if you already have survival as a skill you have expertise in this landscape. 

 

Living Spell Warrior

At 3rd level, you learn to draw on the energy of the living spells that roam the mournlands and infuse your attacks with it. 

As a bonus action, choose one creature you can see within 30 feet of you. The next time you hit that creature on this turn with a weapon attack, all damage dealt by the attack becomes elemental,  and the creature takes an extra 1d8 damage from the attack. The number on the D8 determines it's element. When you reach 11th level in this class, the extra damage increases to 2d8, chosing one for it's elemental damage.

Mirage of the Mourning

At 7th level, you learn to augments your surroundings . As an action, you can cast the mirage arcane spell with this feature, without expending a spell slot, but the spell ends at the end of your next long rest. 

Once you use this feature, you can’t use it again until you finish a long rest.

Living Spell Soul

When you take the Attack action, you may roll upon the wild magic surge table from wild magic barbarian, as living spells surge aground you, with any durations lasting a minute or until you are incapacitated. You may only do this once per short rest. 

Dead-gray form

At 15th level, your bond with the Mournlands increases, giving you a almost misty visage and grey pallor. When you take damage from an attack, you can use your reaction to give yourself resistance to all of that attack’s damage on this turn, as you become slightly intangible.
