Consider using an Elixir of Fire Resistance

Staff Swing  Astaroth will swing his staff around to strike you and can drain your life in one hit D2R ladder items. Fire breathing  Astaroth will breathe out flames which scorch and damage you over time.

Fire balls  These searing meteors rain from above with little warning.

The key to beating Astaroth is to dodge into him and attack his rear as often as you can. This will help you avoid several attacks, such as the flames the hellhound can breathe out and the fiery scythe Astaroth can swing. So long as you stick relatively close to his rear, Astaroth’s attacks won’t land. He can also quickly turn around and pounce, so be sure to dodge to the side to avoid taking damage. Consider using an Elixir of Fire Resistance to mitigate as much of his fire damage as possible.

Another thing to keep an eye on is where the projectiles land. Occasionally, Astaroth will summon fiery meteors to strike the ground, leaving behind a crater filled with flames. These craters do significant damage over time, so you may wish to back off for a while and lead Astaroth to a safer space to fight him in. Eventually, after each phase, Astaroth will run away, so you can chase him down.

After the first phase, he’ll begin summoning smaller hellhounds to bite you. They’re relatively weak but serve to prolong the fight as much as possible. He soon begins to add Werewolves to the mix, which are more challenging than the regular wolves. His meteor strike attack also has more of them strike the ground, setting more of the battlefield on fire. Keep at it, though d2r items for sale, and eventually, after a total of four life phases, you’ll bring down the demon and seal him once more. You should receive at least one Legendary item as a reward for beating him.
