Lightning Elemental

Summary
The Lightning Elemental is a tier II boss. Its design is simple, yet sweet. It's a rocky figure connected by beams of electricity. It is also the first boss to have healing orbs that you must destroy to prevent it from healing. They rest upon 4 pillars in the arena, and you must shoot them to deactivate them. The Lightning Elemental resides far up in an arena above a volcano.

Background Story
A substantial gravitational anomaly was detected in an obscure mountain valley. Team ██████ were transmitted to the mountains to investigate the situation. It took weeks of preparation due to a severe storm that was headed to the valley. However, they were finally prepared to take on the grueling hike.

It was cold and desolate on the mountain peaks. It was so quiet, that it almost seemed as if the men were the last people on the planet. The eerie silence was shattered by the roaring of the incoming storm. They decided to seek shelter inside of a nearby cave, planning to wait out the storm. Yet, things didn't go as expected.

It didn't take long for a string of terribly unfortunate events to occur. The storm was so harsh that it caused an avalanche to occur. Rocks tumbled down the mountain, putting the men's lives at stake.

The storm had carried an unknown sort of cosmic energy, as it imbued some of the rocks with incredibly strong otherworldly power. It spawned a devastatingly strong elemental made of rocks, inoculated with lightning and electricity. It was the last thing the team saw before they died.

The entrance to the cave was sealed off by the tumbling rocks, leaving the men to slowly rot inside of the cave.

Months later, a rescue team, █████ came to save the investigators, but it was too late. They had already rotted away, but the creature had not fled. It was stronger than before, and slaughtered most of the rescue team. A few members had gone missing; presumed to have gotten lost in the depths of the caverns.

The beast hid away at the summit of the mountain, to safely construct smaller incarnations of itself. It was increasingly becoming more powerful, to the point where it could cause devastating, irreversible damage.

Tips

 * The Lightning Elemental electrifies the arena as it walks over it.
 * Watch out for gaps in the arena, you can easily fall off if you aren't aware of your position.
 * When it performs its Electric Tremor attack, get on top of one of the clouds. They cannot be electrified.
 * Deactivate the healing orbs as soon as possible. They can heal the elemental very fast.
 * Keep in mind that the orbs WILL regenerate.
 * Stay off of the yellow tiles. They are electrified and you will take damage when you stand on them.

Trivia

 * This boss used to be as hard as the amethyst elemental until it's major nerf.
 * Currently the only boss that has had its arena changed 3 times.
