The tasmt\xc3\xa1s 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 tasmt\xc3\xa1s, 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 tasmt\xc3\xa1s, or half as much on a successful DC 15  Constitution  saving throw. In addition, if it fails this saving throw the tasmt\xc3\xa1s gains one level of  exhaustion . \n'b' Hallow permanently ruins the nest and causes the tasmt\xc3\xa1s 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 tasmt\xc3\xa1s are reduced by 20 (6d6), and it cannot regain these  hit points  until its new nest is complete. \n'b'  Drought Aura . The tasmt\xc3\xa1s 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. \n'b'  Mastery Against Flyers . The tasmt\xc3\xa1s 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). \n'b'\n'b' ACTIONS \n'b'\n'b'  Multiattack . The tsamt\xc3\xa1s makes three bite attacks. \n'b'  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. \n'b'  Wing Ripper . If the tsamt\xc3\xa1s 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 tsamt\xc3\xa1s 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. \n'b'\n'b' REGIONAL EFFECTS \n'b' The region containing a tsamt\xc3\xa1s\xe2\x80\x99 lair becomes hotter and drier as it is tainted by the creature\xe2\x80\x99s presence. \n'b'\n'b' 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 tasmt\xc3\xa1s 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. \n'b' 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\xe2\x80\x99s discretion). \n'b' If  control weather  is cast within 5 miles of the tsamt\xc3\xa1s\xe2\x80\x99 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. \n'b'\n'b' ABOUT \n'b' A tsamt\xc3\xa1s (plural tsamt\xc3\xa1x) 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 tsamt\xc3\xa1s stretches nearly 40 feet long and weighs several tons, though gas bladders within it bear it aloft. \n'b'  Sky Hunter . The tsamt\xc3\xa1s 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\xe2\x80\x99 flesh or if it is a deeper enmity rooted in their feathered rivals\xe2\x80\x99 control of the weather. After all, how can the tsamt\xc3\xa1s 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 tsamt\xc3\xa1s are a terrible menace, the elder abominations that spawned them are even worse. Larger and far deadlier than their common kin, the toset\xc3\xa1x can bring ruin to entire nations if its foul influence is left unchecked. Aside from its greater size, the toset\xc3\xa1x bears the same red and green scales and ivory underbelly of the tsamt\xc3\xa1s, though its hateful eyes glow a lambent green.'
