Some content about the Black Star boss in Path of Exile from clairerr's blog

Need to fight the new Black Star boss in Path Of Exile? The Siege Of The Atlas expansion pack has arrived, bringing four new endgame bosses to Path of Exile. Players can travel through Atlas and enter these new battles with a new story progression, each with some deadly new mechanics. The Black Star is especially unique in that it can easily overwhelm the unsuspecting. So players need to prepare enough POE Archnemesis Currency to compete with the boss easily.

The Black Star Arena Mechanics: The Polaric Void. The entire Black Star battle revolves around the center of the arena. When players load into the Polaric Void, they immediately notice the center globe. That globe emits two flames that divide the arena into a fiery red half and an ice blue half. The Earth will rotate throughout the fight and move halfway with it. Each side inflicts stacking debuffs on the player, making them more vulnerable to this type of damage and its associated ailments. However, they also Buy POE Currency of the opposite type. This is the key to surviving the Black Star’s most dangerous attack.

The Black Star has two extremely powerful abilities: Astral Avalanche and Solar Storm. These attacks will kill the player almost instantly if they have a matching debuff. However, with the opposite debuff, they don’t do any damage at all. Players can buy POE Orbs to strengthen themselves and take less damage. The Black Star’s other attacks, including those used by its clone, also deal with massive fire and cold damage.

Thankfully, players can also reduce this by sticking to the right part of the arena. Or they can buy Path of Exile Currency to get some useful gear to reduce damage. The Black Star seems to switch elements after Astral Avalanche and Solar Storm, so skip to the other half at the end. Players should also make sure they are immune to Freeze or have a way to remove it before starting combat. Otherwise, a cold attack on the wrong side of the arena will get them into trouble.
