Traits

Chilling Acidic Body

A creature that touches the frostveil or hits it with a melee attack while within 5 feet of it takes 4 (1d8) acid damage.

Damage Transfer

While engulfing a creature, the frostveil takes only half the damage dealt to it (rounded down), and the engulfed creature takes the other half.

False Appearance

While the frostveil remains motionless, it is indistinguishable from a formation of frost and ice.

Windborne

In windy conditions, the frostveil’s flying speed increases to 30 feet. In a wind of moderate or greater speed (at least 10 miles per hour), its flying speed increases to 60 feet.

Actions

Frozen Tendril

+7 to hit, reach 10 ft (3 m). Hit: 1d8+5 plus 1d6 cold damage.

Melee Weapon Attack: +7 to hit, reach 10 ft., one target. Hit: 9 (1d8 + 5) bludgeoning damage plus 3 (1d6) cold damage.

Multiattack

The frostveil makes two Frozen Tendril attacks. If both attacks hit a Medium or smaller target, the target is grappled (escape DC 15), and the frostveil uses Snowy Engulf on it.

Snowy Engulf

The frostveil engulfs a Medium or smaller creature grappled by it. The engulfed target is blinded and restrained, and it must succeed on a DC 15 Constitution saving throw at the start of each of the frostveil's turns or take 4 (1d8) acid damage and 3 (1d6) cold damage. If the frostveil moves, the engulfed target moves with it. The frostveil can have only one creature engulfed at a time.

Spirit Spores

Recharge 6

The frostveil releases a puff of psychotropic spores around itself. Each creature within 10 feet of the frostveil must make a DC 15 Constitution saving throw. On a failure, a creature takes 21 (6d6) cold damage and is incapacitated for 1 minute. On a success, a creature takes half the damage and isn't incapacitated. When an incapacitated creature moves, it moves in a random direction. An incapacitated creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.

GM Tips: Using Frostveil

2 tips available

When using Frostveil in your D&D 5e campaign, consider these tactical approaches:

Flight Control Strategy: Target flying creatures with spells like 'Hold Person', 'Web', or 'Grease' to ground them. Without flight restriction, they can escape melee range easily. Consider area denial spells below their flight altitude to force them into disadvantageous positions.
Cold Damage Strategy: Cold-based attacks can slow or freeze. Prepare 'Heat Metal' or fire spells as countermeasures. Ice terrain can be used to create difficult terrain for melee characters.

When your party encounters this creature, keep these strategies in mind:

Counter Flight Advantage: This creature can fly! Use ranged attacks, reach weapons, or spells like 'Thunderwave' to push it away. Consider 'Gust of Wind' or 'Earthbind' to ground it. Melee characters need fly speed or flight magic to engage.
Cold Damage Protection: This creature deals cold damage! Get cold resistance or use fire spells. Avoid water surfaces - they can freeze and create difficult terrain. 'Heat Metal' can counter cold.
