Storm needs an iron block or End Crystal and consumes the item. After 1.5 seconds of prep it lasts 30 seconds, cooldown 150 seconds. Strikes start at 2 damage and grow by 2 + Intelligence × 0.05; search radius 6 blocks.
The Soul Sceptre creates a storm beast: if you take 30 or more damage in 3 seconds, lightning lines fire after 1.5 seconds (30 second cooldown).
