  • Crystal Clarity (recharge 5-6). When the mistlurker makes an ability check or saving throw, it can cause a magical wave of calm to wash over it that allows it to access and approach the task at hand as if time were slowed. It rolls 1d6 and adds the result to the roll.
  • Heart of Ice. The mistlurker can channel its elemental legacy at will, allowing it to coat itself in ice. It ignores difficult terrain, has advantage on ability checks and saving throws made to deal with freezing terrains and environments, and when taking the Dodge action it gains a bonus to its armor class equal to its proficiency bonus (+3). Additionally, the Mistlurker can see normally within the range of its own fog cloud spell.
  • Innate Spellcasting. The mistlurker’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):
  • Mist Flourish. When the mistlurker casts the misty step spell, it creates a temporary misty haze and can attempt to take the Hide action as part of the same bonus action as if it had total cover. If successful, it remains unseen until the end of its turn even if it is in plain sight.
  • Sneak Attack (1/turn). When the mistlurker hits a creature with a weapon attack using a light weapon and has advantage on the attack roll (or their target is engaged with another creature within 5 feet of them who isn’t incapacitated), the mistlurker deals an extra 14 (4d6) damage on that attack.


  • Multiattack. The mistlurker makes two weapon attacks, choosing between its freezing scimitar and frost knife for either. When it uses its frost knife, the mistlurker magically creates a knife of ice and throws it at a target, only to have it shatter after it strikes or misses.
  • Freezing Scimitar. Melee Weapon Attack: +7 to hit, reach 5 ft., 1 target. Hit: 8 (1d6+4) slashing damage plus 6 (1d10) cold damage.
  • Frost Knife. Ranged Weapon Attack: + 7 to hit, range 20/60 ft., 1 target. Hit: 7 (1d4+4) magic piercing damage and 6 (1d10) cold damage


  • Ice Deflection. As a reaction to being hit with a weapon attack, the mistlurker can thicken ice on its skin to reduce the damage it takes by 10 (1d6 + 6) points. If the damage was cold damage, it takes none instead.


The mistlurker is a kyanite crystal tiefling who has tapped into their innate powers over ice to strike at enemies in a manner that disorients them. They are assassin-like, trying to exploit weaknesses in their targets’ defenses and subject them to icy conditions the tiefling would have an advantage in. Usually working as bodyguards or spies, they are like ghosts in the fog who strike then flee from their targets.
