How to Defeat a Ruin Grader in Genshin Impact

Last Updated: July 6, 2021

A ruin grader is an enemy in Genshin Impact that can potentially cause severe damage to your character's health and/or block your path for a good while. Defeating a ruin grader is not impossible, though; with the right strategy, you will be able to avoid serious health damage, while at the same time progressing towards defeating the enemy.

Steps

1
Know which characters you will need. You will mostly need characters that can participate in melee combat. Your Traveler is okay for melee combat, but Claymore characters like Beidou and Xinyan are probably going to do the job more easily. You can use an archer, but it will probably not be as useful as a Claymore.

Part 1 of 2:
Avoiding Damage

1
Dodge the Ruin Grader's clap. In this attack, the ruin grader moves towards you and then uses its hands to smash you. Immediately after, it will fire a laser in your direction. Move away from the clap and the laser to dodge.
2
Avoid the spinning attack. Like the ruin guard, the ruin grader can spin to hit you with its arms. When this happens, move outside of the area of effect (AoE) to avoid heavy damage.
3
Stay away from the glowing orbs. The ruin grader will launch honing orbs at you to try to deal more damage. These orbs persist on the ground and deal damage if you are too close to them.
4
Avoid the charged attack. In this attack, the ruin grader will charge towards you. Move to the side to avoid getting massive damage.
5
Dodge the lasers. The ruin grader will fire targeted lasers towards you to deal even more damage. Run to avoid the concentrated lasers.

Part 2 of 2:
Dealing Damage

1
Attack the cores in its feet twice. Using Claymore, you can hit both cores in the ruin grader's feet when exposed. You can also use elemental skill to your advantage.
- After attacking for the first time, the cores will lock, and you will be unable to attack it. After the second attack, the ruin grader will be unable to move. It will continue to be able to fire lasers at you.
2
Fire at the ruin grader's eye twice when it is firing lasers or launching orbs. This will fully disable the ruin grader, allowing you to deal more damage to the enemy.
3
Continue using melee weapons after the ruin grader is disabled. The ruin grader will remain crouching for 15-30 seconds and then reactivate. Use this window to deal additional damage.
- If you only disable the laser, the Ruin Grader will still be able to stomp on you, and if you only disable the feet, the Ruin Grader will still be able to fire lasers.
4
Repeat to defeat the ruin grader. If done correctly, the ruin grader will effectively be defeated, dropping a chaos device. You may also get a chest unlocked that can drop valuable materials and/or result in you leveling up.

Question

I'm preparing to fight this for the In The Mountain's Quest. How can I conserve HP?

Zhongli, Archon of Liyue (Aasim)

Community Answer

The best way to conserve HP is to bring healers with you in your party. Choose someone like Barbara or Qiqi as they are dedicated healers and will always regenerate HP for your party, regardless of build. Diona, Noelle, Xinyan, and Zhongli are also good as they can generate shields to help prevent you taking damage.

Warnings

If it is obvious that your characters are losing a lot of health, teleport to a Statue of the Seven to regenerate health and consider fighting when your party and/or adventure level is higher.

Thanks!
