This guide will let you know how to beat GEO HYPOSTASIS World Boss in Genshin Impact.
First, you need to equip Noelle or any other character who can damage the pillars and break them because the pillars always protect the boss.
When he attacks you and forms the shape of a large hammer, you have to run away. Then right after the attack, you have to come back and attack the boss because he will be in the unprotected form now.
And when he is in his protected form, you have to break the pillars with Noelle because she is the best hero in the game to break the pillars fast compared to others.
Now you have to destroy all of the pillars around the arena and watch the boss and dodge his attacks. When you see a circle shape around your character, it means the boss will attack you, so you have to run and move from that position. After that, you have to go and hit the boss because he is not under the protection of the pillars, and it is the best time to attack and damage him.
When the boss shoots and attacks you, you have to get behind their pillar and let him complete the attack, which will damage their pillar, as shown in the image below.
When the boss starts to do a shock wave to the pillar, you have to go away from the pillar and stand where you have destroyed the pillar to be safe from his attack.
When the boss is in low health, he will summon three last pillars, and you have only 15 seconds to destroy these pillars. So you need to use Noelle and do the full combo by pressing the left click, and you will easily break all the three pillars and kill the boss.
