A lightning storm, commonly referred to most players as an "E-Storm", is a rare occurrence that takes place during night; an E-Storm in previous versions of the game used to be identifiable by the purplish-whitish lightning bolts that would appear across the sky, as well as many lightning flashes across the entire map.
The purple lightning was removed about 2020.
To identify an Electric Storm now, there are 2 conditions that must be met:
- It’s night
- It’s storming
During an "E-Storm," gem ores become more common and you have the chance to get a very rare ore called Electrosteel, which has the appearance of a neon white. To gain Electrosteel during an E-Storm, you must have an Angelic Sapphire Pickaxe (a pick made of Angelwood and Sapphire) on a non-spawn island. These are Perth, Fenwick, Freeport, Salem, Cannoneer's Key, and The Nameless Isles. Please note that Harrisburg resources act like if they were as spawn island so you can’t get electrosteel here.
The chance of an E-Storm to happen are very slim, coming in at an 8% chance every night.
During winter, E-Storms are replaced with Snowstorms (also referred to as Ice Storms). During a Snowstorm you obtain ice instead of electrosteel.
