Solar Eclipse

Solar Eclipse is a extremely powerful developer only boss.

Design
It features as a Black Circle with a Xyv guardian turret on top and a barrel which looks like a incognito barrel which both shoot Permanent EMP effects that stun forever.

Technical
Solar Eclipse is immensely durable and is very powerful, The guardian auto-turret shoots extremely high penetration health and damage crashers with high reload high initial launch speed and medium speed which deal infinite EMP. The front cannon shoots EMP upon Right click and doesn't have any left click ammunition but the EMP is infinite though it doesn't have as much range as Surges EMP shot does. And it has a lot of health, MUCH MORE THAN ANY OTHER BOSS IN THE GAME

Countering
Take a group of ideally 4-5 surges since it can deflect the EMP and a İcicle to kill it But you will need 2-4 tanks ideally smashers for distraction since it can kill you all before you even get close. İf you can do this, just melt its health without letting it escape from the EMP, If you can do this before it obliterates you all, congrats, you killed one of the strongest things in the game.

Trivia

 * This boss doesn't have a AI since the dev are very determined of not making one.
