Traits

Elemental Nature

The slow storm doesn’t require air, food, drink, or sleep.

Eye of the Storm

The slow storm is surrounded by a 15-foot-radius wind storm. The storm imposes disadvantage on ranged weapon attack rolls and Wisdom (Perception) checks based on sight or hearing within the area. The winds extinguish open flames and disperse fog. A flying creature in the storm must land at the end of its turn or fall. Each creature that starts its turn in the area must succeed on a DC 18 Dexterity saving throw or take 9 (2d8) lightning damage. The storm’s area is difficult terrain for any creature other than the slow storm.

Actions

Lightning Bolt

+9 to hit, range 120 ft (36.6 m). Hit: 4d8+4 lightning damage.

Ranged Spell Attack: +9 to hit, range 120 ft., one target. Hit: 22 (4d8 + 4) lightning damage.

Multiattack

The slow storm makes three Slam attacks or four Lightning Bolt attacks. If two Slam attacks hit one creature, the target must succeed on a DC 18 Constitution saving throw or be wracked with pain for 1 minute. While the target is wracked with pain, minute bits of electricity dance within its body, and the target takes 4 (1d8) lightning damage for every 5 feet it moves. The target can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.

Slam

+10 to hit, reach 5 ft (1.5 m). Hit: 3d10+5 plus 2d8 lightning damage.

Melee Weapon Attack: +10 to hit, reach 5 ft., one target. Hit: 21 (3d10 + 5) bludgeoning damage plus 9 (2d8) lightning damage.

Static Shock

Recharge 5–6

The slow storm releases built-up electricity in a 60-foot cone. Each creature in the area must make a DC 18 Constitution saving throw, taking 54 (12d8) lightning damage on a failed save, or half as much damage on a successful one. A creature that fails this saving throw by 5 or more is also stunned for 1 minute. A stunned 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 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.

2 strategies available

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.
