Thuellai
Airborne creatures have disadvantage on attack rolls against the thuellai.
The thuellai see perfectly well in snowy conditions. It does not suffer Wisdom (Perception) penalties from snow, whiteout, or snow blindness.
Actions
All creatures within 10 feet of a thuellai take 7 (2d6) cold damage at the beginning of the thuellai’s turn. Spells or magical effects that protect against cold are affected as if by a dispel magic spell (the theullai’s effective spellcasting bonus is +5) if a thuellai is within 20 feet of the target at the start of the theullai’s turn, and nonmagical flames within 20 feet of the thuellai are extinguished at the start of its turn.
The thuellai creates an icy blizzard in the area around it. A 50-foot radius sphere surrounding the theullai fills with icy fog, whirling snow, and driving ice crystals. Vision is lightly obscured, and creatures have disadvantage on Wisdom (Perception) checks that rely on vision or hearing. The ground in the affected area becomes difficult terrain. The effect lasts for 10 minutes and moves with the theullai.
The thuellai exhales an icy blast in a 40-foot cone. Each target in the area takes 39 (6d12) cold damage, or half damage with a successful DC 17 Constitution saving throw.
a thuellai’s howl can cause creatures to temporarily lose their minds and even to attack themselves or their companions. Each target within 100 feet of the theullai and able to hear the howl must make a successful DC 14 Wisdom saving throw or roll 1d8 and consult the table below at the start of its next turn. An affected creature repeats the saving throw at the end of each of its turns; a success ends the effect on itself, but a failure means it must roll again on the table below at the start of its next turn.
