Sentient Cloud

A rare species of lifeform featured in Kern that straetofolk sometimes transform into after dying of natural causes. Sentient clouds are written about in mythology and heavily inspire art, music, and folklore in Straetos.

They generally simply observe the world as they float around it, though they sometimes may intervene with humanoid affairs.

False Appearance. The sentient cloud is indistinguishable from an ordinary cloud.

Lightning and Radiant Absorption. Each time the sentient cloud takes Lightning or Radiant damage, it instead gains hit points equal to the amount of damage done by the move.

Wind Vulnerability. The sentient cloud is especially vulnerable to powerful gusts of wind that can threaten to disperse it through the atmosphere.

Unusual Nature. The sentient cloud does not require food, drink, or sleep.

Siege Monster. The sentient cloud deals double damage to structures and objects.

Unusual Composition. If a sentient cloud is reduced to 0 hit points or scattered, such as by a powerful gust of wind, it assimilates back into the earth’s atmosphere and into other clouds elsewhere. The sentient cloud may choose to re-form itself and become active again after 1d10 days.

Innate Spellcasting. The sentient cloud’s innate spellcasting ability is Wisdom (spell save DC 19, +11 to hit with spell attacks). Each sentient cloud is different, but they may have access to the following spells:

At will: Call Lightning (9th level, 10d10). The cloud formed by the spell is the sentient cloud itself. Chain Lightning (9th level, 13d8), Lightning Bolt (9th level, 14d6)

1/day each: Control Weather, Whirlwind, Wind Walk

1/month: Storm of Vengeance. The cloud formed by the spell is the sentient cloud itself.

Actions

Thunderstorm. The sentient cloud uses an action to cast Lightning Bolt at 9th level.

Bonus Actions

Call Lightning. If the sentient cloud is concentrating on the Call Lightning spell, it can call a lightning bolt with a bonus action during its turn.
