Special Traits

• Darkness. The dark swirling clouds that surround the Grindlwere should be treated as magical darkness in a 30 foot radius around the creature.
• Windblast. A storm surrounds the creature at all times. Creatures within 60 ft. of the creature are at disadvantage to all Strength and Dexterity ability checks as well as all concentration checks. Any creature of Small or smaller size must make a Strength save (DC 10) at the end of each turn it is within the cloud. On a failed save, the creature is knocked prone.
• Cloudform. The creature is almost entirely a cloud and is surrounded by clouds. It has advantage on all stealth checks while in an area of clouds or fog. The creature can pass through any crack that normal fog could get through

Actions

• Lightning Burst (Recharge 5-6). The Grindlwere infuses itself with electricity and hurls itself as a bolt of lightning. The creature travels in a straight line up to 90 feet. This creates a bolt 10 feet wide and as long as the creature’s move. Each creature in this area must make a Dexterity Save (DC 14). On a failed save, they take 35 (10d6) lightning damage, or half on a successful save.
• Lightning Fists. Melee Weapon Attack: +6 to hit, reach 10 ft., one target. Hit: 13 (2d8+4) lightning damage.

About

The grindlwere is a fiend that comes to life in the bosom of giant storms. Born of the chaos embodied in the violent conflicts of the elements, the creature manifests as a living entity without discernable shape or form. They appear only as a darker mass in the deep dark clouds, for this is where the creature comes to life, drawing the power of the storm within it. They express themselves through the forked tongues of their lightning, which they hurl constantly. This is the most visible form the creature takes; a rush of thick cloud that follows the arc of its own energy as it strikes those around it. The cloud assumes an almost tangible shape as it follows the arcing electricity.

Clouds Within Clouds. The grindlwere possess no physical form beyond that of the storm which gives them life. They do not eat or need any sustenance; they draw their energy from the storms itself. Their life ends when the storm passes and the magic that gave birth to it fades. These creatures are almost impossible to detect until the storm itself brews, at such times those experienced enough may detect the creature as a ball of lightning or strange undulating darkness in the clouds.

Mindless Destroyers. These creatures thrive on violence and attack by thundering down upon their victims with a massive bolt of lightning. This is often the first hint that someone has they are being attacked. They are unreasoning creatures without the ability to speak or understand for they hardly recognize that they are alive. On rare occasions, encounters with more than one occur, but these happen only in the midst of massive storms.

At such times the grindlwere never act in concert or for that matter, even recognize that another grindlwere is present.
