  • Edge of Perception. An obsidian tiefling possesses an aura that makes them hard to concentrate on. Their movement does not provoke opportunity attacks.
  • Innate Spellcasting. An obsidian tiefling’s spellcasting ability is Charisma (Spell Attack +6, Spell Save DC 14). It can innately cast the following spells, requiring no material components (these spells are cast as if by a 3rd level spell slot):
    • 2/Day each: chaos bolt
    • 1/Day each: darkness
  • Shroud of Emptiness. The obsidian tiefling is not considered to be any specific alignment or creature type. Spells that target it and require specific creature types or alignments fail to affect them.
  • Superior Critical. Due to others finding it hard to keep track of their movements, the obsidian tiefling can exploit openings easily. They score a critical hit on attack rolls of 18, 19 or 20.


  • Multiattack. The obsidian tiefling makes two greataxe attacks.
  • Greataxe. Melee Weapon Attack: + 6 to hit, reach 5 ft., 1 target. Hit: 10 (1d12 + 3) slashing damage plus 5 (1d8) necrotic damage


  • Clouded Mind. As a reaction to being hit by a weapon attack, the obsidian tiefling may force its attacker to make a DC 15 Wisdom saving throw. If they fail they briefly forget that the obsidian tiefling exists, just long enough for the attack to harmlessly miss them.
  • Inverse Rejuvenation. When a creature would regain hit points within 60 feet of the obsidian tiefling by a magic item or spell, they can use their reaction to force the creature to regain no hit points, and instead take necrotic damage equal to half the amount of hit points they would have regained. Alternatively, if a creature within that range takes necrotic damage, this feature causes them to take no damage and gain temporary hit points equal to half the necrotic damage instead.


Obsidian tieflings are entrenched in the corrupting influence of the Plane of Negative Energy, able to deceive the senses of others simply by standing before them. Their ties to the Material Plane are fleeting, and the world is ever so gently trying to remove the negative energy they harbor at any given time. They take advantage of this, using this strange quality to vanish from the perception of others when it is convenient for them.
