Hyper-Volt

Hyper-Volt takes a ball lightning and gives it a Mythic price tag. Created by xcvbwer123 for Era 2, it rolls at 1 in 7,500,000 with no biome tied to it, meaning about 7.5 million rolls at 1x luck or 750,000 at 10x. It has a rarer mutation named Hyper-Volt : Ever-Storm, which is exactly 30 times rarer.

The Sol's RNG Wiki says it is very similar in design to Sol itself. Six purple electricity orbs rotate around the player in two layers, three inner orbs linked by thick light purple beams forming a counter-clockwise triangle, and three outer orbs turning clockwise. A purple sigil with a fixed lightning bolt in the center spins behind the back, and the player hovers in a unique pose above an aura on the ground.

The in-game description frames it as a phenomenon science still doubts: clusters of low-temperature plasma forming sudden flashes mid-air, powerful enough to be mistaken for a natural disaster, with chaotic currents circling unpredictably.
