Traits

Bone Wrack

When hit by the slow storm's slam or breath weapon attack, the storm absorbs moisture from the living creatures' joints, causing stiffness and pain. In addition to 1d4 Dexterity drain, any creature caught within the slow storm's breath weapon that fails another DC 18 Constitution save suffers crushing pain in bones and joints. Any round in which the pained creature moves, it takes 1d4 necrotic damage per 5 feet moved. Bone wracking pain lasts until the affected creature regains at least 1 point of lost Dexterity.

Innate Spellcasting

the slow storm's innate spellcasting ability is Wisdom (spell save DC 16). It can innately cast the following spells, requiring no material components:

at will: lightning bolt

3/day: chain lightning

Storm Form

A creature that enters or starts its turn inside the slow storm's whirlwind takes 9 (2d8) force damage. A creature can take this damage just once per round. In addition, ranged missile weapon attacks against the slow storm have disadvantage because of the high-speed wind.

Actions

Slam

+10 to hit, reach 15 ft (4.6 m). Hit: 4d12 piercing damage.

Melee Weapon Attack: +10 to hit, reach 15 ft., one target. Hit: 31 (4d12 + 5) bludgeoning damage plus 9 (2d8) piercing damage.

Static Shock

Recharge 5–6

The slow storm exhales its electrical power in a 30-foot cone. Targets in the area of effect take 54 (12d8) lightning damage, 1d4 Dexterity loss, and suffer bone wrack. A successful DC 18 Constitution saving throw halves the Dexterity loss and prevents the bone wrack.

GM Tips: Using Slow Storm

2 tips available

When using Slow Storm 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.
Lightning Damage Awareness: Lightning attacks often have long range and high speed. Advise players to use cover and avoid metal armor/weapons. Water surfaces amplify lightning damage - avoid fighting near water.

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.
Lightning Damage Protection: This creature deals lightning damage! Avoid metal armor and weapons. Use cover and avoid water surfaces. 'Iron Skin' or 'Protection from Energy' can help.
