From D&D Wiki
|This material is published under the OGL 1.0a.
Medium undead (vampire), chaotic evil
Saving Throws Dex +5, Wis +4
False Visage. A thuull that has recently fed on a living being can use its action to cast disguise self, transforming into a form resembling its unburnt self for up to 1 hour. Attacking spoils the disguise and the thuull must feed again to resume it.
Regeneration. The thuull regains 10 hit points at the start of its turn if it has at least 1 hit point and isn’t in sunlight or running water. If the thuull takes radiant damage or damage from holy water, this trait doesn’t function at the start of it’s next turn.
Spider Climb. The thuull can climb difficult surfaces, including upside down on ceilings, without needing to make an ability check.
Vampire Weaknesses. The thuull has the following flaws:
Shapechanger. If the thuull isn’t in sun light or running water, it can use its action to polymorph into a cloud of burning ash. While in ash cloud form, the thuull can’t take any actions, speak, or manipulate objects. It is weightless, has a flying speed of 20 feet, can hover, and can enter a hostile creature’s space and stop there. In addition, if air can pass through a space, the cloud can do so without squeezing, and it can’t pass through water. It has advantage on Strength, Dexterity, and Constitution saving throws, and it is immune to all non-magical damage, except the damage it takes from sunlight. A creature in the thuull’s ash cloud takes 5 (1d8) fire damage must make a Constitution saving throw DC 13 or be blinded for 1 turn. A creature that fails this save on two or more consecutive turns becomes blinded for 1 turn and gains a level of exhaustion.
Multiattack. The thuull makes two attacks, only one of which can be a bite attack.
Slam. Melee Weapon Attack: +6 to hit, reach 5 ft., one willing creature, or a creature that is grappled by the thuull, incapacitated, or restrained. Hit: 6 (1d6 + 3) piercing damage plus 7 (2d6) necrotic damage. The target’s hit point maximum is reduced by an amount equal to the necrotic damage taken, and the thuull regains hit points equal to that amount. The reduction lasts until the target finishes a long rest. The target dies if this effect reduces its hit point maximum to 0.
Slam. Melee Weapon Attack: +6 to hit, reach 5 ft., one creature. Hit: 8 (2d4+3) slashing damage. Instead of dealing damage, the thuull can grapple the target.
Some vampires are driven by a bloodlust so powerful, even the pyre cannot keep them from seeking to satiate it. A thuull is one such vampire, their undead body destroyed by fire or sunlight but somehow capable of reanimating their burnt remains to terrorize the living yet again. While not as cunning or powerful as a full-fledged vampire, the thuull often makes up for this with their unbridled savagery and insatiable need to consume every scrap of life that falls into their grasp. Although sunlight still burns a thuull, it cannot destroy them. During the day, a thuull collapses into a pile of ash and remains in its resting place, but if holy water is poured on these remains, it is utterly destroyed.
