Emperor of Fire and Iron in Genshin Impact: How to Find and Defeat

In Genshin Impact The Emperor of Fire and Iron is a giant crab and elite boss, added to the game With You with the release of update 4.0. It drops Emperor’s Resolution, which is required to exalt certain characters. In this guide, you will be able to find out where you can find this enemy, which team should be prepared to fight him, and how to defeat him the fastest.

Where to find the Emperor of Fire and Iron

This boss does not require any additional conditions to be unlocked, so you can essentially access it immediately after completing the Archon quest "Song of the Dragon and Freedom". However, we still advise you to start with Fontaine's quest chain.

So first of all get to Fontaine by choosing one of the two possible ways. Then head to the southern part of the Bello area. Go to the beach and then dive into the water. In the place shown in the screenshots below, find the entrance to the underwater tunnel and start diving down.

Along the way, you will be able to collect a Hydroculus. Then emerge from the water and get out on land. You will enter an underground cave. Run forward and activate the teleport on the left. In the distance, you will notice an arena with a boss waiting for you.

Respawn Emperor of Fire and Iron

After you deal with this boss, it will respawn in about 3-5 minutes - you need to teleport to another area or restart the game for the giant crab to spawn again. Remember also that in order to collect rewards, you will have to spend 40 units from it primordial resin.

Characteristics of the Emperor of Fire and Iron

Even in the normal state, this opponent has 60% Pyro resistant, but to other types of damage (including physical), its resistance is only 10%. When he puts a Noelle: Protector on himself with a horn, the resistance to all elements of the crab increases by 60%. All this imposes certain restrictions on the selection of characters to fight this boss.

If we talk about the combat parameters of this sea creature, then it has average health indicators, but its attack power significantly exceeds similar values. Monstrous Baptist or Setekh Wenut. For example, at level 90, his base HP is 445 thousand units (the baptist has 371 thousand), and ATK is 17.1 thousand units (the baptist has 15.2 thousand). You can see all the characteristics of the enemy in the image below (2P, 3P and 4P show the parameters when playing in co-op).

Hero Selection Tips

Considering the boss's average health bar and huge attack power, we advise you to pay as much attention to the survivability of the squad as to its damage. If you see that your shielder cannot cope with the incoming damage, then you can safely take a healer into the pack as well. It will help to heal after powerful attacks of the enemy in the area.

Primary and secondary damage can be Electro, Hydro, Cryo, Dendro, Anemo and/or Geo elements, however we recommend sticking with the first three elements as they combine best with Pyro to create the reactions needed to destroy the boss's shield (more more on this below).

You can also try to collect a pack for physical damage, which often consists of main-DD and sub-DD, related to Cryo and Electro elements. Thus, you can not only apply a large physical. damage, but also destroy the Noelle: Protector of the crab.

As for supports, they can be of any element, since their main task will be to increase the elemental damage of damage dealers, that is, they will still attack the enemy infrequently. This also applies to shieldmen and healers.

How to defeat the Emperor of Fire and Iron

Preparing for battle

Before the start of the battle, you can eat dishes that increase attack power, critical damage and critical hit chance. It will be useful to drink potions that increase certain elemental damage in order to strengthen your damage dealers. In this case, it will be useful:

• Streaming Essential Oil - Increases Hydro damage by 25% for 5 minutes.
• Forest Essential Oil - Increases Dendro's damage by 25% for 5 minutes.
• Frosting Essential Oil - Increases Cryo damage by 25% for 5 minutes.
• Shocking Essential Oil - Increases Electro damage by 25% for 5 minutes.
• Unmoving Essential Oil - Increases Geo damage by 25% for 5 minutes.

The boss also mainly deals Pyro damage, so we recommend you take a Heatshield Potion, which increases resistance to Pyro damage by 25% for 300 seconds.

Combat strategy

Everything is pretty simple here. At the very beginning of the battle, the Emperor of Fire and Iron will already have a double horn, so your main task will be to destroy him. To do this, attack him with elements that interact with Pyro - Hydro (1st place) and Electro (2nd place) attacks work best in this case.

When the double horn is destroyed, the enemy will fall to the ground and you can hit him with impunity for a few seconds. It will then use basic hits, and after a while it will burrow underground and crawl out with new horns - repeat the above process.

Note that in close combat, it is possible to hit the horns of a crab if the enemy lowers his head a little down. For this reason, if you want to constantly deal damage to the horns, then take an archer or a catalyst into the squad.
