Here's the Dall-E prompt I used for the image

Create an image in the style of AD&D cover art of a group of adventurers fighting against a hooded figure wielding a glowing blue katana and using elemental powers, with an ancient altar to the elemental gods in the background.


The party is traveling through a dense forest when they come across an ancient altar nestled among the trees. The altar is adorned with symbols of the four elements - fire, water, air, and earth - and seems to radiate a powerful energy.

As the party approaches the altar, they are confronted by a hooded figure clad in black robes and carrying a katana at their side. The figure charges at the party, unleashing a barrage of elemental attacks as they approach. The party realizes that they are facing a ninja elementalist, a member of a secretive clan who wield the power of the elements to accomplish their missions.

The party fights back, using their skills and powers to defend themselves against the ninja elementalist's elemental attacks and swift sword strikes. As the battle rages on, the party realizes that the energy of the altar is affecting their ability to use their own elemental powers. They must use their wits and skills to outmaneuver the ninja elementalist and emerge victorious.

With the ninja elementalist defeated, the party has the opportunity to explore the altar and uncover its secrets. According to legend, the altar was built by a group of powerful elementalists who sought to harness the primal energy of the elements. They believed that by channeling this energy through the altar, they could gain immense power and control over the natural world.

The party discovers that the altar is still connected to the elemental planes, and that it holds a great deal of untapped power. They must decide whether to leave the altar untouched, or to risk unleashing its power and potentially attracting the attention of other elementalists or even the elemental gods themselves.

Elemental Affinity. The ninja elementalist has a connection to the elements, allowing them to harness the power of fire, water, air, or earth in combat. They can use their action to cast the following spells:

  • Fireball (3rd level, once per day). The ninja elementalist hurls a ball of fire at a target within 120 feet, dealing 8d6 fire damage to all creatures in a 20-foot radius.
  • Control Water (2nd level, once per day). The ninja elementalist can manipulate the water within a 30-foot radius, raising or lowering the level of water or moving it in any direction.
  • Gust of Wind (2nd level, once per day). The ninja elementalist creates a gust of wind in a 60-foot line, pushing creatures back 10 feet and knocking them prone if they fail a Strength saving throw.
  • Stone Shape (2nd level, once per day). The ninja elementalist can reshape stone in a 5-foot radius, creating a passageway or blocking an area.

Unarmored Defense. While the ninja elementalist is not wearing armor, their AC equals 10 + their Dexterity modifier + their Wisdom modifier.

Keen Senses. The ninja elementalist has proficiency in the Perception skill.

Evasion. When the ninja elementalist is subjected to an effect that allows them to make a Dexterity saving throw to take only half damage, they take no damage on a successful save, and only half damage on a failed save.

Elemental Katana

Very Rare, requires attunement

This sleek, curved katana is made of a shimmering blue metal that seems to pulsate with a faint, otherworldly energy. It is said to have been crafted by a group of powerful elementalists who imbued it with the essence of the elements themselves.

The katana has the following properties:

  • You gain a +1 bonus to attack and damage rolls made with this weapon.
  • When you hit a creature with this weapon, you can choose to deal an additional 1d6 elemental damage of your choice - fire, cold, lightning, or poison.
  • As an action, you can channel the power of the elements through the katana, creating a blast of energy that radiates out in a 15-foot cone. Each creature in the cone must make a Dexterity saving throw, taking 3d6 elemental damage of your choice on a failed save, or half as much damage on a successful one. You can use this ability once per day.
