  • Desecrated Nest. The tasmtás builds its nest on high, inaccessible spires, as it fears the blessings of priests and shamans. Pouring holy water on its nest deals 7 (2d6) radiant damage to the tasmtás, as does casting a bless spell at its nest. This damage can be dealt only once per round, no matter how much holy water or how many bless spells are used. Dispel evil and good cast upon the nest deals 35 (10d6) radiant damage to the tasmtás, or half as much on a successful DC 15 Constitution saving throw. In addition, if it fails this saving throw the tasmtás gains one level of exhaustion.
  • Hallow permanently ruins the nest and causes the tasmtás to become poisoned until it can construct a new nest, which takes it 1d6 + 1 days. Each day that passes, the maximum hit points of the tasmtás are reduced by 20 (6d6), and it cannot regain these hit points until its new nest is complete.
  • Drought Aura. The tasmtás radiates an oppressive heat within 60 feet, causing creatures to take 7 (2d6) fire damage each round at the beginning of their turn. In addition, any living creatures in this area that are at fewer than half of their maximum hit points (and any aquatic creature not currently in the water, regardless of hit points) must succeed on a DC 16 Constitution saving throw each round or gain one level of exhaustion. A creature cannot gain more than one level of exhaustion in this fashion.
  • Mastery Against Flyers. The tasmtás gains a +1 bonus on attack rolls against flying creatures as well as on saving throws against spells and magical abilities used by flying creatures (including those using magical spells or similar effects to gain the power of flight).


  • Multiattack. The tsamtás makes three bite attacks.
  • Bite. Melee Weapon Attack: +11 to hit, reach 15 ft., one target. Hit: 18 (2d10 + 7) piercing damage plus 7 (2d6) fire and 7 (2d6) necrotic damage on a successful hit.
  • Wing Ripper. If the tsamtás hits a creature that uses wings to fly with two bites in the same round, the target takes an additional 11 (2d10) piercing damage and must succeed on a DC 19 Strength saving throw or its wings are damaged, reducing its fly speed by half until it completes a short rest or receives a regenerate spell. If the tsamtás hits such a creature with all three bites in the same round, the extra damage is increased to 16 (3d10) and the save DC is increased to 21.


The region containing a tsamtás’ lair becomes hotter and drier as it is tainted by the creature’s presence.

  • Weather conditions within a 5-mile radius become one step hotter, winds are calmed by one step, and precipitation is reduced by one step (see the control weather spell). Each additional tasmtás that is present in the same area can choose to increase the radius of this effect by 5 miles or to increase each effect by one step.
  • Surface water sources within 1 mile of its lair become warm, bitter, and sulfurous, with shallow ponds and streams drying up within 1 week (GM’s discretion).
  • If control weather is cast within 5 miles of the tsamtás’ nest, it can spend 10 minutes focusing its drought aura to dispel it, as if it had cast dispel magic using Wisdom as its spellcasting ability.


A tsamtás (plural tsamtáx) is a bizarre, vaguely serpentine creature that lives suspended in the upper reaches of the air as the endless blistering it radiates scorches the land below into a sere wasteland. Each end of its serpentine body ends in a huge set of jaws, while the heaving belly in the center of its body bears a third massive gaping orifice. The tsamtás stretches nearly 40 feet long and weighs several tons, though gas bladders within it bear it aloft.

Sky Hunter. The tsamtás seeks to devour all avian creatures, but its favorite prey are the thunderbirds that soar across the highland plateaus. It is not known whether this is due to the save of the thunderbirds’ flesh or if it is a deeper enmity rooted in their feathered rivals’ control of the weather. After all, how can the tsamtás bring ruin and waste to the lands below and the skies above if the thunderbird is allowed to bring rain to the land? Father Devourer. While the ordinary tsamtás are a terrible menace, the elder abominations that spawned them are even worse. Larger and far deadlier than their common kin, the tosetáx can bring ruin to entire nations if its foul influence is left unchecked. Aside from its greater size, the tosetáx bears the same red and green scales and ivory underbelly of the tsamtás, though its hateful eyes glow a lambent green.
